Number of items in $list
Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $ListCnt function is Count.
This function returns an integer that, if positive, contains the number of items in the specified $list and if negative indicates an error.
The $ListCnt function accepts one argument and returns a numeric result.
The first argument is a $list identifier. This is a required argument.
Syntax
%result = $ListCnt(list_identifier)
%result is set either to the number of items in the indicated $list, or to a negative number if an error has occurred.
Error codes
-5 - Required argument not specified -6 - $List identifier invalid
