Memory:<br>
<br>
Maximum lines of code is 10000.<br>
Maximum operands in an expression is 200.<br>
Maximum variables is 500.<br>
Maximum arrays is 500 with 1000 maximum elements each.<br>
Maximum declared functions is 100.<br>
<br>
Expressions:<br>
<br>
Operator precedence is !, *, /, %, +, -, <, >, <=, >=, =, <>, XOR, AND, OR, ^<br>
AND may be written as &.<br>
OR may be written as |.<br>
XOR may be written as ~.<br>
! is the not operator.<br>
% is the mod operator.<br>
^ is the power operator.<br>
Functions have no precedence over any operators.<br>
Floating point numbers are supported.<br>
The negative operator is supported.<br>
Parentheses may be used to override order of operations.<br>
White space is optional.<br>
<br>
Variables:<br>
<br>
Variables and arrays are double precision.<br>
<br>
Variable names a-z are pre defined.<br>
All other variable names may consist of numbers and letters only.<br>
Define variables by using let varname=0 with 0 as any value.<br>
The define command may be used to bulk let commands together.<br>
Omit the let and Use commas to separate the definitions.<br>
<br>
Define arrays by using dim arrayname[arraysize].<br>
The arraysize can be a variable or value.<br>
Arrays are zero indexed and may only be one dimension.<br>
<br>
Custom Defined Functions:<br>
<br>
Define functions with the define command.<br>
Function definitions may be mixed in with variable definitions.<br>
All definitions are separated by commas.<br>
Functions are a customizable array of expression strings.<br>
Functions may be named similarly to variables.<br>
Function names must be written in parenthesis without space between.<br>
Functions are artery, but may use global variables.<br>
<br>
The functions may be used anywhere in expressions.<br>
The return value is the evaluation of the function string.<br>
<br>
There's no precedence for custom functions.<br>
Functions may only be defined once. More than once wastes memory.<br>
<br>
Pre Defined Functions:<br>
<br>
There are artery and unary pre defined functions.<br>
<br>
Artery functions must be written in parenthesis without space between.<br>
<br>
Unary functions must have a colon in front of it without space between.<br>
Unary functions pass whatever comes in front of it as a parameter.<br>
<br>
Pre defined functions have no precedence.<br>
Precedence must be established with parenthesis for unary functions.<br>
Wrap the unary function and it's parameter in parenthesis when needed.<br>
This way, full expressions may be used as parameters for the function.<br>
<br>
For example, let x=int:10/3 works fine, but not if int:(rnd)*3 = 1 then.<br>
It must be written as if (int:(rnd)*3)=1 then.<br>
<br>
Syntax:<br>
<br>
Input may optionally have a prompt with double quotes, comma, variable.<br>
Arrays and functions may be used wherever expressions are used.<br>
Arrays may by used with the input and button commands.<br>
<br>
Output may be combined in print, alert, and title using commas.<br>
Output may include numbers, expressions, and double quoted text.<br>
Output may also include the word comma to display a comma.<br>
<br>
Distribution:<br>
<br>
Craft Basic may be used as a scripting language by associating .bas files.<br>
If you prefer to distribute the program as an .exe, follow these steps.<br>
First, copy and paste Craft Basic.exe to the distribution directory.<br>
Then copy your programs .bas file to the same directory.<br>
Rename Craft Basic.exe to match the .bas file.<br>
Change the .bas file extension to a .run file.<br>
The result should look like myprogram.exe and myprogram.run.<br>
When you run the resulting exe, your program will execute automatically.<br>
Now you may include a readme and zip it up.<br>
<br>
Known issues:<br>
<br>
For some reason, -2^2 doesn't evaluate correctly.<br>
If you hold down ctrl R for a long time, the program will crash.<br>
