The commands you need can be found in the run menu, the last option in 
the prg menu. Put the input data and the program on the stack and press 
DBUG. You can then single step through the program using SST or SST
(down arrow). The latter will also single step through any program 
called by the first. For a long program an alternative is to insert a 
HALT in the program where you think the problem might be. Having 
examined the stack at this point you can then KILL of CONT (rightshift 
on).

Hope this is helful
