In the case of a user program which is passed to DOLIST, you can't. It is being run repeatedly within the confines of the single DOLIST step, so when you SST through that command all of the invocations have already occurred.

Normally you can insert the RPL sequence "41 MENU HALT" to force a debugging interruption anywhere you like, but HALT isn't allowed within a user program that is passed to DOLIST.

Your best bet would simply be to create a "test program" that sets up the subroutine in question with suitable stack contents and just executes it once without using DOLIST. Then you should be able to SST through the various steps to follow its progress.
