Carets are also used in computer programming languages for various reasons. For example, in Perl, a user may use the below regular expression to replace the first character in the variable "myvariable" with an uppercase character. Many programs that support regular expressions (Regex) will use ^ to match the first character in a line or string.
$myvariable =~ s/^(\w)/\U$1/g;
In C-style programming languages, the caret is used for a bitwise XOR.
