 +
 +======Technical:======
 +This function is used to determine the length, in characters, of a given

 +======Practical:======
 +This function is effectively the same as the $@var notation, except that

 +
 +======Returns:======
 +| >0  | number of characters in string |
 +|  0  | no string given                |
 +
 +======Examples:======

 +$strlen(epic is cool)          returns "12"
 +</file>
