{$?PARMS} - Query: How many parameters were passed? |
The subject of macros is reasonably complex (but well worth learning) please ensure you have at least read the macro introduction before reading this section.
This query ("{$?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).
