Case-sensitivity of identifiers
Case-sensitivity of identifiers is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Three dogs (Are there three dogs or one dog?) is a code snipped 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.
Perl
<lang perl>
# These variables are all different $dog='Benjamin'; $Dog='Samba'; $DOG='Bernie'; print "The three dogs are named $dog, $Dog, and $DOG \n"
</lang>
PureBasic
<lang PureBasic>dog$="Benjamin" Dog$="Samba" DOG$="Bernie" Debug "There is just one dog named "+dog$</lang>
