Suspending a Running PML Macro

If you cannot find out what is going wrong by means of PML trace output or writing out the values of PML variables, you may suspend a running PML file at a particular point by including the command:

$M-

You can then query the values of any PML variables of interest and even change the values of some PML variables. To resume processing of the suspended PML file, type into the command line:

$M+

Use these facilities only for debugging and do not leave these commands in a finished PML file.

Note:
These facilities do not apply to PML functions or methods.
