Using Macros and Functions Together

The existing mechanism for invoking a macro using $M continues to be available alongside the new PML functions. Most PML code in existing macros should continue to work unmodified.

To call a macro, even from within a PML function, use the $M command. Variables used as arguments to a macro must be STRING values. PML variables must be converted to a STRING with a preceding $:

$M filename $!X $!Y $!Z

Note:
To gain the full benefits of using PML functions, it is best not to mix macros and functions extensively. Many of the advantages of PML functions depend on using variables without $ which is not possible with arguments to macros.
