I agree with Francois, using LOOKUP% as alternative for EXISTS.
I use it a lot. It returns the place in the name table which can also be
used to test for conflicting keywords if found out of place.

Lookup% can not distinguish between
SCR_XLIM and SCRXLIM
http://www.dilwyn.me.uk/tk/scrxlim.zip
if SCRXLIM_cde is loaded
print Lookup% ("SCR_XLIM") gives 160
print Lookup% ("SCRXLIM") gives 162
conclusion
QDOS -> EXISTS_bin
SMSQE -> Function_code
