;" This code module will allow tracing through code.
;" It is used as follows:
;"
;" set $ZSTEP="do STEPTRAP^TMGTRSTP($ZPOS) zstep into zcontinue"
;" zstep into
;" do ^MyFunction ;"<--- put the function you want to trace here
;"
;" set $ZSTEP="" ;"<---turn off step capture
;" quit
;"
;"
;" Dependencies:
;" Uses TMGTERM
;"
;"Notes:
;" This function will be called inbetween lines of the main
;" program that is being traced. Thus is function can't do
;" anything that might change the environment of the main
;" program. This includes accessing global variables --
;" because it will mess up the "naked reference".

STEPTRAP(Pos)
;"Purpose: This is the line that is called by GT.M for each zstep event.
;" It will be used to display the current code execution point, and
;" query user as to plans for future execution: run/step/ etc.
