Yep.

It's hard to describe the behavior I'm getting because it's so odd,
and doesn't seem totally consistent.  But at first, Step and Go both
do basically nothing other than displaying the .ENTRY line of code.
If I CANCEL BREAK/ALL and then set a breakpoint at the first
executable line "MOVL 12(AP),R6"  and then type go, it runs through
the program without stopping at the breakpoint.

If I clear all breaks and then SET BREAK/LINE and then type GO or STEP
it will run through the program without hitting the breakpoint  BUT
then each succeeding call of the program will cause it to stop at the
next line of code.  I just did this several times until it hit an
unknown architected break instruction fault.  I'm completely
confused.  I've debugged Macro programs before - even these shareable
images - and have never run into this behavior before.
