i assume the OP is referring to osq-debug.  I used it once upon a many
moons ago.  basically, it will print each block of code as it
executes, and print the values of selected variables at that time.  It
works by generating a temporary file with each block of code
duplicated inside a message box.  It was also, IIRC, somewhat fragile,
in that is was easy to get it generate code that would compile and
die....
