Description
The FILTER() function returns the current filter condition as a string.  If no filter is set, the FILTER() function returns a null string.  If the optional <workarea | alias> is specified, then the function will return the active filter condition for the specified <workarea | alias>.  Filters are set for a workarea using the SET FILTER command.  The FILTER() has no effect on the SET FILTER command.
