Looking at the code for CallorGo, I found this interesting snippet: XPLeNCODE v2.0 b-gin [UNTITLED] {<}SX50,"File """+@UPR({<}IS50{>})+""" not found"{>} -nd XPLeNCODEI figured that it was supposed to put a literal quote into part of s/g 50. When I tried to run it, however, I got an error message:SX command requires a number. "File """+@UPR(«IS50»)+""" not found"Interestingly, using RUNCODE on the defined block in the U2 didn't give an error.Harry Binswanger hb@xxxxxxxx
