Synopsis:
$strlen(<string>)
Technical:
This function is used to determine the length, in characters, of a given
string.
Practical:
This function is effectively the same as the $@var notation, except that
$@var only works for variables, not functions or automatic expandos.
Returns:
>0 number of characters in string
0 no string given
Examples:
$strlen($1-3) returns length of args $1 to $3
$strlen(epic is cool) returns "12"
