{$?PARMS} - Query: How many parameters were passed?

The subject of macros is reasonably complex (but well worth learning) please ensure you have at least read the macro introduction before reading this section.

This query ("{$?PARMS}") can be used in a macro for a quick and simple test to tell if the "caller" of the macro passed any parameters or to find out how many (0 returned if none).
