You are encouraged to solve this task according to the task description, using any language you may know.
Three dogs (Are there three dogs or one dog?) is a code snippet used to illustrate the lettercase sensitivity of the programming language. For a case-sensitive language, the identifiers dog, Dog and DOG are all different and we should get the output:
The three dogs are named Benjamin, Samba and Bernie.
For a language that is lettercase insensitive, we get the following output:
There is just one dog named Bernie.

ALGOL 68
A joke code entry... :-) ¢ but the code does actually work! File: Case-sensitivity_of_identifiers.a68<lang algol68>#!/usr/bin/a68g --script #
- -*- coding: utf-8 -*- #
STRING dog = "Benjamin"; OP D = (INT og)STRING: "Samba"; OP DOG = (INT gy)STRING: "Bernie"; INT og=~, gy=~;
main:(
printf(($"The three dogs are named "g", "g" and "g"."l$, dog, Dog, DOGgy)); 0
)</lang>Output:
The three dogs are named Benjamin, Samba and Bernie.
Alternative version.
Most recent implementations of Algol 68 use "upper stropping", the "keywords" are in upper case and the identifiers are an lower case. This precludes use of e.g. Dog or DOG as the name of a variable or constant.
However, depending on the "stropping" convention used and the implementation, Algol 68 can be case-sensitive. Rutgers ALGOL 68 uses quote stropping and allows both upper and lower case in identifiers and bold words. The standard bold words must be in lower-case.
<lang algol68>'begin'
'string' dog = "Benjamin"; 'begin' 'string' Dog = "Samba"; 'begin' 'string' DOG = "Bernie"; 'if' DOG /= Dog 'or' DOG /= dog 'then' print( ( "The three dogs are named: ", dog, ", ", Dog, " and ", DOG ) ) 'else' print( ( "There is just one dog named: ", DOG ) ) 'fi' 'end' 'end'
'end'</lang>
- Output:
The three dogs are named: Benjamin, Samba and Bernie
ALGOL W
Algol W identifiers are not case-sensitive but variable names in inner blocks can be the same as those in outer blocks... <lang algolw>begin
string(8) dog; dog := "Benjamin"; begin string(8) Dog; Dog := "Samba"; begin string(8) DOG; DOG := "Bernie"; if DOG not = Dog or DOG not = dog then write( "The three dogs are named: ", dog, ", ", Dog, " and ", DOG ) else write( "There is just one dog named: ", DOG ) end end
end.</lang>
- Output:
There is just one dog named: Bernie

bc
The only variables are 'a' through 'z'. They can only hold numbers, not strings. Some implementations allow longer names like 'dog', but only with lowercase letters. A name like 'Dog' or 'DOG' is a syntax error.
<lang bc>obase = 16 ibase = 16
/*
* Store the hexadecimal number 'BE27A312' * in the variable 'd'. */
d = BE27A312 "There is just one dog named "; d quit</lang>

He is a New Foundland echo The three dogs are named Benjamin, Samba and Bernie</lang>
C
C is case sensitive; if it would be case insensitive, an error about redefinition of a variable would be raised.
<lang c>#include <stdio.h>

These are the style warnings from SBCL. Other implementations of Common Lisp might give different warnings.
Crystal
<lang crystal>dog = "Benjamin" Dog = "Samba" DOG = "Bernie"
puts "The three dogs are named #{dog}, #{Dog} and #{DOG}."</lang>
Note that in Crystal, variables with all-caps identifiers (like DOG
) are always constants.
- Output:
The three dogs are named Benjamin, Samba and Bernie.
D
<lang d>import std.stdio;
void main() {
string dog = "Benjamin"; // identifiers that start with capital letters are type names string Dog = "Samba"; string DOG = "Bernie"; writefln("There are three dogs named ", dog, ", ", Dog, ", and ", DOG, "'");
}</lang> Output:

dc
A register name has only one character, so this example uses 'd' and 'D'.
<lang dc>[Benjamin]sd [Samba]sD [The two dogs are named ]P ldP [ and ]P lDP [. ]P</lang>
- Output:
The two dogs are named Benjamin and Samba.
Delphi
Delphi is case insensitive.
<lang Delphi>program CaseSensitiveIdentifiers;
{$APPTYPE CONSOLE}
var
dog: string;
begin
dog := 'Benjamin'; Dog := 'Samba'; DOG := 'Bernie'; Writeln('There is just one dog named ' + dog);

DWScript
<lang Delphi> var dog : String;
dog := 'Benjamin'; Dog := 'Samba'; DOG := 'Bernie';

EchoLisp
<lang scheme> (define dog "Benjamin") (define Dog "Samba") (define DOG "Bernie")
(printf "The three dogs are named %a, %a and %a. " dog Dog DOG)
The three dogs are named Benjamin, Samba and Bernie.
</lang>
Elena
In ELENA identifiers are case sensitive. ELENA 4.x: <lang elena>import extensions;
public program() {
var dog := "Benjamin"; var Dog := "Samba"; var DOG := "Bernie"; console.printLineFormatted("The three dogs are named {0}, {1} and {2}", dog, Dog, DOG)
}</lang>
- Output:
The three dogs are named Benjamin, Samba and Bernie
Elixir
While Elixir's identifiers are case-sensitive, they generally must start with a lowercase letter. Capitalized identifiers are reserved for modules. <lang elixir>dog = "Benjamin" doG = "Samba" dOG = "Bernie" IO.puts "The three dogs are named #{dog}, #{doG} and #{dOG}."</lang>
- Output:
The three dogs are named Benjamin, Samba and Bernie.
Erlang
Erlang variables are case sensitive but must start with an uppercase letter. <lang Erlang> -module( case_sensitivity_of_identifiers ).
-export( [task/0] ).
task() -> catch dog = "Benjamin", % Function will crash without catch Dog = "Samba", DOG = "Bernie", io:fwrite( "The three dogs are named ~s, ~s and ~s~n", [dog, Dog, DOG] ). </lang>
- Output:

Euphoria
<lang Euphoria>-- These variables are all different sequence dog = "Benjamin" sequence Dog = "Samba" sequence DOG = "Bernie" printf( 1, "The three dogs are named %s, %s and %s\n", {dog, Dog, DOG} )</lang>
F#
F# is case-sensitive. <lang fsharp>let dog = "Benjamin" let Dog = "Samba" let DOG = "Bernie" printfn "There are three dogs named %s, %s and %s" dog Dog DOG</lang>
Factor
Factor identifiers are case-sensitive. <lang factor>USING: formatting locals ; IN: scratchpad [let
"Benjamin" :> dog "Samba" :> Dog "Bernie" :> DOG { dog Dog DOG } "There are three dogs named %s, %s, and %s." vprintf
]</lang>
- Output:

Forth
<lang forth>: DOG ." Benjamin" ;
- Dog ." Samba" ;
- dog ." Bernie" ;
- HOWMANYDOGS ." There is just one dog named " DOG ;
HOWMANYDOGS</lang>
- Output:
There is just one dog named Bernie
Fortran
Fortran is case insensitive, and so the three "dog" variants name the same variable - which therefore is multiply declared and will likely evoke a compiler complaint. <lang fortran>program Example
implicit none
character(8) :: dog, Dog, DOG
dog = "Benjamin" Dog = "Samba" DOG = "Bernie"
if (dog == DOG) then write(*,*) "There is just one dog named ", dog else write(*,*) "The three dogs are named ", dog, Dog, " and ", DOG end if
end program Example</lang> Output:
There is just one dog named Bernie

Go
Go is case sensitive. Further, visibility depends on case. See the Go entry under the Scope modifiers task. <lang go>package dogs
import "fmt"
// Three variables, three different names. // (It wouldn't compile if the compiler saw the variable names as the same.) var dog = "Salt" var Dog = "Pepper" var DOG = "Mustard"
func PackageSees() map[*string]int {
// Print dogs visible from here. fmt.Println("Package sees:", dog, Dog, DOG) // Return addresses of the variables visible from here. // The point of putting them in a map is that maps store only // unique keys, so it will end up with three items only if // the variables really represent different places in memory. return map[*string]int{&dog: 1, &Dog: 1, &DOG: 1}
}</lang> <lang go>package main
import (
. "dogs" "fmt"
)
func main() {
// with the dogs package imported, there are three dogs. d := PackageSees() fmt.Println("There are", len(d), "dogs.\n")
// Declaration of new variable dog. It lives in this package, main. dog := "Benjamin" d = PackageSees() fmt.Println("Main sees: ", dog, Dog, DOG) // Four dogs now. two of the three visible from here are the // the same as ones in the dogs package. d[&dog] = 1 d[&Dog] = 1 d[&DOG] = 1 fmt.Println("There are", len(d), "dogs.\n")
// Not a declaration, just an assigment. This assigns a new value to // the variable Dog declared in the package. Dog is visible because // it begins with an upper case letter. Dog = "Samba" // same four dogs, same three visible, one just has a new name. d = PackageSees() fmt.Println("Main sees: ", dog, Dog, DOG) d[&dog] = 1 d[&Dog] = 1 d[&DOG] = 1 fmt.Println("There are", len(d), "dogs.\n")
// Of course you can still declare a variable if you want to. This // declares a new variable, shadowing DOG in the package and rendering // it inaccessable even though it begins with an upper case letter. var DOG = "Bernie" // five dogs now. three visible from here. d = PackageSees() fmt.Println("Main sees: ", dog, Dog, DOG) d[&dog] = 1 d[&Dog] = 1 d[&DOG] = 1 fmt.Println("There are", len(d), "dogs.")
}</lang>
- Output:
Package sees: Salt Pepper Mustard There are 3 dogs. Package sees: Salt Pepper Mustard Main sees: Benjamin Pepper Mustard There are 4 dogs. Package sees: Salt Samba Mustard Main sees: Benjamin Samba Mustard There are 4 dogs. Package sees: Salt Samba Mustard Main sees: Benjamin Samba Bernie There are 5 dogs.
Groovy
Solution: <lang groovy>def dog = "Benjamin", Dog = "Samba", DOG = "Bernie" println (dog == DOG ? "There is one dog named ${dog}" : "There are three dogs named ${dog}, ${Dog} and ${DOG}.")</lang>
Output:
There are three dogs named Benjamin, Samba and Bernie.
Haskell
Identifiers are case sensitive in Haskell, but must start with a lower case letter.
<lang Haskell>import Text.Printf
main = printf "The three dogs are named %s, %s and %s.\n" dog dOG dOg
where dog = "Benjamin" dOG = "Samba" dOg = "Bernie"</lang>
Icon and Unicon
The program below demonstrates the three dog task. All variants of Icon/Unicon have case sensitive variable names. But if one wasn't this would find it. <lang Icon>procedure main()
dog := "Benjamin" Dog := "Samba" DOG := "Bernie"
if dog == DOG then write("There is just one dog named ", dog,".") else write("The three dogs are named ", dog, ", ", Dog, " and ", DOG, ".")
end</lang>
J
<lang j> NB. These variables are all different
dog=: 'Benjamin' Dog=: 'Samba' DOG=: 'Bernie' 'The three dogs are named ',dog,', ',Dog,', and ',DOG
The three dogs are named Benjamin, Samba, and Bernie </lang>
Java
<lang java>String dog = "Benjamin"; String Dog = "Samba"; //in general, identifiers that start with capital letters are class names String DOG = "Bernie"; //in general, identifiers in all caps are constants //the conventions listed in comments here are not enforced by the language System.out.println("There are three dogs named " + dog + ", " + Dog + ", and " + DOG + "'");</lang>
JavaScript
Javascript is case sensitive. <lang javascript>var dog = "Benjamin"; var Dog = "Samba"; var DOG = "Bernie"; document.write("The three dogs are named " + dog + ", " + Dog + ", and " + DOG + ".");</lang>
jq
jq identifiers are case-sensitive.
Function parameters: <lang jq>def task(dog; Dog; DOG):
"The three dogs are named \(dog), \(Dog), and \(DOG)." ;
task("Benjamin"; "Samba"; "Bernie")</lang>
- Output:
$ jq -n -f Case-sensitivity.jq "The three dogs are named Benjamin, Samba, and Bernie."
Variable names: <lang jq>"Benjamin" as $dog | "Samba" as $Dog | "Bernie" as $DOG
| "The three dogs are named \($dog), \($Dog), and \($DOG)."</lang>
- Output:
As above.
Julia
Variable names are case sensitive. <lang julia>dog, Dog, DOG = "Benjamin", "Samba", "Bernie"
if dog === Dog
println("There is only one dog, ", DOG)
else
println("The three dogs are: ", dog, ", ", Dog, " and ", DOG)
end</lang>
- Output:
The three dogs are: Benjamin, Samba and Bernie
Conventionally, variable names should be all lower case. Type and Macro names should be capitalized.
K
<lang k>
dog: "Benjamin" Dog: "Samba" DOG: "Bernie" "There are three dogs named ",dog,", ",Dog," and ",DOG
"There are three dogs named Benjamin, Samba and Bernie" </lang>
Kotlin
Kotlin is case-sensitive though (as in Java) the convention is for local variable names to begin with a lower case letter. The second and third identifiers would therefore be unlikely to be used in practice. <lang scala>fun main(args: Array<String>) {
val dog = "Benjamin" val Dog = "Samba" val DOG = "Bernie" println("The three dogs are named $dog, $Dog and $DOG")
}</lang>
- Output:
The three dogs are named Benjamin, Samba and Bernie
Lasso
Lasso is not case sensitive for names <lang Lasso> local(dog = 'Benjamin') local(Dog = 'Samba') local(DOG = 'Bernie')
stdoutnl('There is just one dog named ' + #dog) </lang> Output:
There is just one dog named Bernie
Same with string comparisons. (Lasso maps can only contain unique keys) <lang Lasso> local(dogs = map( 'dog' = 'Benjamin', 'Dog' = 'Samba', 'DOG' = 'Bernie' )) stdoutnl(#dogs -> size)</lang> Output:
1
To get case sensitivity we need to use bytes <lang Lasso> local(dogs = map( bytes('dog') = 'Benjamin', bytes('Dog') = 'Samba', bytes('DOG') = 'Bernie' ))
stdoutnl(#dogs -> size)
stdoutnl(#dogs -> find(bytes('Dog')))</lang> Output:
3 Samba
Liberty BASIC
NB the IDE warns you that there are similar variables named dog$, Dog$ & DOG$ <lang lb> dog$ = "Benjamin" Dog$ = "Samba" DOG$ = "Bernie" print "The three dogs are "; dog$; ", "; Dog$; " and "; DOG$; "."
end </lang> The three dogs are Benjamin, Samba and Bernie.
Lua
<lang lua>dog = "Benjamin" Dog = "Samba" DOG = "Bernie"

Nim
Nim has peculiar rules regarding case and style sensitivity:
- – it is mainly a case insensitive language;
- – but keywords are all in lowercase;
- – and the first letter of an identifier is case sensitive;
- – moreover, underline is ignored in identifiers (style insensitivity).
With these rules, we don’t get one dog or three dogs: we get two dogs!
<lang Nim>var dog, Dog: string (dog, Dog, DOG) = ("Benjamin", "Samba", "Bernie")
if dog == Dog:
if dog == DOG: echo "There is only one dog, ", DOG) else: echo "There are two dogs: ", dog, " and ", DOG
elif Dog == DOG :
echo "There are two dogs: ", dog, " and ", DOG

Prolog
In Prolog, the initial of a variable must be a uppercase letter. So the task can't be completed but we can write this code : <lang Prolog>three_dogs :- DoG = 'Benjamin', Dog = 'Samba', DOG = 'Bernie', format('The three dogs are named ~w, ~w and ~w.~n', [DoG, Dog, DOG]). </lang> The output is :
?- three_dogs. The three dogs are named Benjamin, Samba and Bernie. true.
PureBasic
<lang PureBasic>dog$="Benjamin" Dog$="Samba" DOG$="Bernie" Debug "There is just one dog named "+dog$</lang>
Python
Python names are case sensitive: <lang python>>>> dog = 'Benjamin'; Dog = 'Samba'; DOG = 'Bernie' >>> print ('The three dogs are named ',dog,', ',Dog,', and ',DOG) The three dogs are named Benjamin , Samba , and Bernie >>> </lang>

- Having fun with cats and dogs
cat('The three dogs are named ') cat(dog) cat(', ') cat(Dog) cat(' and ') cat(DOG) cat('.\n')
- In one line it would be:

Output:
The three dogs are named Benjamin, Samba and Bernie.
Racket
The default setting for the Racket reader is to be case sensitive: <lang Racket>
- lang racket
(define dog "Benjamin") (define Dog "Samba") (define DOG "Bernie")
(if (equal? dog DOG)
(displayln (~a "There is one dog named " DOG ".")) (displayln (~a "The three dogs are named " dog ", " Dog ", and, " DOG ".")))
</lang> Output:
The three dogs are named Benjamin, Samba, and, Bernie.
If you need case insensitive identifiers, then use #ci to turn on case insensitivity: <lang Racket>
- lang racket
- ci(module dogs racket
(define dog "Benjamin") (set! Dog "Samba") (set! DOG "Bernie") (if (equal? dog DOG) (displayln (~a "There is one dog named " DOG ".")) (displayln (~a "The three dogs are named " dog ", " Dog ", and, " DOG "."))))
(require 'dogs) </lang> Output:
There is one dog named Bernie.
Raku
(formerly Perl 6) <lang perl6>my $dog = 'Benjamin'; my $Dog = 'Samba'; my $DOG = 'Bernie'; say "The three dogs are named $dog, $Dog, and $DOG."</lang> The only place that Raku pays any attention to the case of identifiers is that, for certain error messages, it will guess that an identifier starting lowercase is probably a function name, while one starting uppercase is probably a type or constant name. But this case distinction is merely a convention in Raku, not mandatory: <lang perl6>constant dog = 'Benjamin'; sub Dog() { 'Samba' } my &DOG = { 'Bernie' } say "The three dogs are named {dog}, {Dog}, and {DOG}."</lang>
Retro
Retro is case sensitive.

REXX
simple variables
The REXX language is case insensitive (with respect to simple variables). <lang rexx>/*REXX program demonstrate case insensitivity for simple REXX variable names. */
/* ┌──◄── all 3 left─hand side REXX variables are identical (as far as assignments). */ /* │ */ /* ↓ */ dog= 'Benjamin' /*assign a lowercase variable (dog)*/ Dog= 'Samba' /* " " capitalized " Dog */ DOG= 'Bernie' /* " an uppercase " DOG */
say center('using simple variables', 35, "─") /*title.*/ say
if dog\==Dog | DOG\==dog then say 'The three dogs are named:' dog"," Dog 'and' DOG"."
else say 'There is just one dog named:' dog"."
/*stick a fork in it, we're all done. */</lang>
output
──────using simple variables─────── There is just one dog named: Bernie.
compound variables
However, the REXX language is case sensitive (with respect to compound variables, or indices). <lang rexx>/*REXX program demonstrate case sensitive REXX index names (for compound variables). */
/* ┌──◄── all 3 indices (for an array variable) are unique (as far as array index). */ /* │ */ /* ↓ */
x= 'dog'; dogname.x= "Gunner" /*assign an array index, lowercase dog*/ x= 'Dog'; dogname.x= "Thor" /* " " " " capitalized Dog*/ x= 'DOG'; dogname.x= "Jax" /* " " " " uppercase DOG*/ x= 'doG'; dogname.x= "Rex" /* " " " " mixed doG*/
say center('using compound variables', 35, "═") /*title.*/ say
_= 'dog'; say "dogname.dog=" dogname._ /*display an array index, lowercase dog*/ _= 'Dog'; say "dogname.Dog=" dogname._ /* " " " " capitalized Dog*/ _= 'DOG'; say "dogname.DOG=" dogname._ /* " " " " uppercase DOG*/ _= 'doG'; say "dogname.doG=" dogname._ /* " " " " mixed doG*/

Ring
<lang ring> dog = "Benjamin" doG = "Smokey" Dog = "Samba" DOG = "Bernie" see "The 4 dogs are : " + dog + ", " + doG + ", " + Dog + " and " + DOG + "." </lang>
Ruby
Ruby gives a special meaning to the first letter of a name. A lowercase letter starts a local variable. An uppercase letter starts a constant. So dog is a local variable, but Dog and DOG are constants. To adapt this task to Ruby, I added dOg and doG so that I have more than one local variable.
<lang ruby>module FiveDogs
dog = "Benjamin" dOg = "Dogley" doG = "Fido" Dog = "Samba" # this constant is FiveDogs::Dog DOG = "Bernie" # this constant is FiveDogs::DOG
names = [dog, dOg, doG, Dog, DOG] names.uniq! puts "There are %d dogs named %s." % [names.length, names.join(", ")] puts puts "The local variables are %s." % local_variables.join(", ") puts "The constants are %s." % constants.join(", ")
end</lang>
Output:
There are 5 dogs named Benjamin, Dogley, Fido, Samba, Bernie. The local variables are dog, dOg, doG, names. The constants are Dog, DOG.
Run BASIC
<lang runbasic> dog$ = "Benjamin" doG$ = "Smokey" Dog$ = "Samba" DOG$ = "Bernie" print "The 4 dogs are "; dog$; ", "; doG$; ", "; Dog$; " and "; DOG$; "." </lang>
Rust
Rust style dictates that identifiers should be written in snake case, e.g. big_dog, small_dog; whereas types (structs and enums) should be written in camel case, e.g. BigDog, SmallDog. Failing to comply with this standard does not cause a compiler error, but it will trigger a compiler warning, and the culture is very strongly towards compliance with this standard.
<lang rust>fn main() {
let dog = "Benjamin"; let Dog = "Samba"; let DOG = "Bernie"; println!("The three dogs are named {}, {} and {}.", dog, Dog, DOG);
}</lang>
This triggers two warnings at compilation:
<lang><anon>:3:9: 3:12 warning: variable `Dog` should have a snake case name such as `dog`, #[warn(non_snake_case)] on by default <anon>:3 let Dog = "Samba";
^~~
<anon>:4:9: 4:12 warning: variable `DOG` should have a snake case name such as `dog`, #[warn(non_snake_case)] on by default <anon>:4 let DOG = "Bernie";
^~~</lang>
The resulting program will compile and run just fine, producing the output:
<lang>The three dogs are named Benjamin, Samba and Bernie.</lang>
Sather
Though by convention Sather uses all uppercase letters for class names, a variable can be all uppercase.
<lang sather>class MAIN is
main is dog ::= "Benjamin"; Dog ::= "Samba"; DOG ::= "Bernie"; #OUT + #FMT("The three dogs are %s, %s and %s\n", dog, Dog, DOG); end;
end;</lang>
Outputs:
The three dogs are Benjamin, Samba and Bernie
Scala
<lang scala>val dog = "Benjamin" val Dog = "Samba" val DOG = "Bernie" println("There are three dogs named " + dog + ", " + Dog + ", and " + DOG + ".")</lang> Output:
There are three dogs named Benjamin, Samba, and Bernie.
Scheme
Output may differ depending on implementation. <lang scheme>(define dog "Benjamin") (define Dog "Samba") (define DOG "Bernie")
(if (eq? dog DOG)
(begin (display "There is one dog named ") (display DOG) (display ".") (newline)) (begin (display "The three dogs are named ") (display dog) (display ", ") (display Dog) (display " and ") (display DOG) (display ".") (newline)))</lang>
Seed7
<lang seed7>$ include "seed7_05.s7i";

SenseTalk
As a People Oriented Programming language, SenseTalk's variable names are case-insensitive. <lang sensetalk> set dog to "Benjamin" set Dog to "Samba" set DOG to "Bernie"
put !"There is just one dog named dog." </lang>

- Output:
The three dogs are named Benjamin, Samba, and Bernie.
Simula
Simula identifiers are case-insensitive, and the compiler will indignantly reject a program that tries to declare multiple variables with names differing only in case. (Same with key words: Case of a character in Simula code generally only matters in a simple string or a character constant.) <lang simula>begin
text dog; dog :- blanks( 8 ); dog := "Benjamin"; Dog := "Samba"; DOG := "Bernie"; outtext( "There is just one dog, named " ); outtext( dog ); outimage
end</lang>
- Output:
There is just one dog, named Bernie
Smalltalk
Smalltalk's symbols are case sensitive.
<lang smalltalk>|dog Dog DOG| dog := 'Benjamin'. Dog := 'Samba'. DOG := 'Bernie'. ( 'The three dogs are named %1, %2 and %3' %
{ dog . Dog . DOG } ) displayNl.</lang>
Outputs:
The three dogs are named Benjamin, Samba and Bernie
SNOBOL4
<lang snobol4> DOG = 'Benjamin'
Dog = 'Samba' dog = 'Bernie' OUTPUT = 'The three dogs are named ' DOG ', ' Dog ', and ' dog

in
print("The three dogs are named " ^ dog ^ ", " ^ Dog ^ ", and " ^ DOG ^ ".\n")

VBA
VBA is case sensitive case insensitive. The variable names 'dog', 'Dog' and 'DOG' can not co-exist. <lang vb>Public Sub case_sensitivity()
'VBA does not allow variables that only differ in case 'The VBA IDE vbe will rename variable 'dog' to 'DOG' 'when trying to define a second variable 'DOG' Dim DOG As String DOG = "Benjamin" DOG = "Samba" DOG = "Bernie" Debug.Print "There is just one dog named " & DOG

There is just one dog named Bernie
Wren
Identifiers in Wren are case sensitive. <lang ecmascript>var dog = "Benjamin" var Dog = "Samba" var DOG = "Bernie" System.print("The three dogs are named %(dog), %(Dog) and %(DOG).")</lang>

The three dogs are named Benjamin, Samba and Bernie.
XBS
In XBS variable names are case-sensitive. <lang xbs>set dog="Benjamin"; set DOG="Samba"; set Dog="Bernie"; log(`The three dogs are named {dog}, {DOG} and {Dog}.`);</lang>
- Output:
The three dogs are named Benjamin, Samba and Bernie.
XLISP
XLISP is entirely case-insensitive. The user can decide whether to have the system print symbols, etc., in capitals or in lower case, by assigning to the variable *PRINT-CASE*. <lang xlisp>(SETQ DOG 'BENJAMIN) (SETQ Dog 'SAMBA) (SETQ dog 'BERNIE) (DISPLAY `(THERE IS JUST ONE DOG NAMED ,DOG))</lang> There is, in any event, only one dog.
(THERE IS JUST ONE DOG NAMED BERNIE)
XPL0
XPL0 is normally case-insensitive, so there is really just one dog named Bernie. However, it has a command-line switch (/c) that turns case sensitivity on. All names must start with a capital letter (or an underline, so they can't clash with command words such as 'for'). Thus "dog" cannot be used as a name, but Dog, DOG and DoG (and For) can. The intent of the command-line switch (/c) is to detect inconsistent capitalizing of names such as Ascii and ASCII or CpuReg and CPUReg.
Yabasic
Yabasic names are case sensitive: <lang yabasic> dog$ = "Benjamin" Dog$ = "Samba" DOG$ = "Bernie" print "The three dogs are named ", dog$, ", ", Dog$, " and ", DOG$ end</lang>
zkl
<lang zkl>var dog = "Benjamin", Dog = "Samba", DOG = "Bernie";</lang>
- Output:
vars L(L("DOG","Bernie"),L("Dog","Samba"),L("dog","Benjamin"))
