Syntax

GET_FILTER( [ cAlias ] )

Purpose

Get the filter currently in effect in a given work area, if any.

Arguments

     cAlias -- if passed, alias of work area to search for filter;
                   defaults to current work area

Setup

cAlias must be a valid work area. Conditional index filters must be
held in the public array aafilter[]. Thus, if not being called from
THE_USUAL(), INIT_QUERY() must be called first.

Example

     USE CUSTOMER
     SET FILTER TO ACCOUNT_NO > "10010"
     ? GET_FILTER() && --> 'ACCOUNT_NO > "10010"'

Returns

If a filter is in effect, it is returned, otherwise, "" is returned.

Side Effects

Crash on bad setup.

Artful Calls

None.
