Hi,

I sometimes have the same problem. I wrote myself a tiny function
"is_debug" and add a debug keyword to the functions I'm testing. My code
then reads somewhat like this:

PRO procedure_to_be_tested, param1, param2, debug=debug

this_debugvalue = 8
if not keyword_set(debug) then debug=0

for i=0,10000 do begin
for j=0,10000 do begin
for k=0,10000 do begin
do something
endfor
endfor
if is_debug(this_debugvalue,debug) then stop
endfor

FUNCTION is_debug, debug, value

RETURN, (debug AND value) eq value

END

If you set this_debugvalue to the n-th power of 2, you have a check
whether the n-th bit is set within the debug variable. Then, if the n-th
bit of debug is set, your procedure will stop. It will run normally
without stop, if you don't call it with the debug keyword.

I'm pretty sure there's a more elegant solution, but it works for me;

Best regards,
Ingo
