Release CCATEMP storage used for $list

Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $ListDel function, but stringlists can be emptied of content with the Empty (Stringlist subroutine).

This function releases CCATEMP storage containing $list items, which helps reduce CCATEMP usage and possibly reduce disk I/O. The information contained in the $list is lost after a $ListDel.

Note that while it is not strictly necessary to $ListDel any $list since they are cleaned up at the termination of the current procedure, the processing for $ListDel is considerably more efficient than end of evaluation cleanup and can actually reduce CCATEMP I/O.

The $ListDel function accepts one argument and returns a numeric result. It is a callable $function (see Calling Sirius Mods $functions).

The only argument is the identifier of the $list that is to be deleted.

Syntax

<section begin="syntax" />[%RESULT =] $ListDel(list_identifier) <section end="syntax" />
