$ListChk

Validate a $list identifier

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $ListChk function.

This function returns either a 0 if a value is not a valid $list identifier and a 1 otherwise.

The $ListChk function accepts one argument and returns a numeric result.

The first argument is a potential $list identifier. This is a required argument.

Syntax

<section begin="syntax" />%result = $ListChk(list_identifier) <section end="syntax" />

$ListChk Function

%result is set either to 1, if the passed value is indeed a valid $list identifier, or to 0 otherwise.
