a) you may not have a clear screen utility
b) look at the manual for Rexx - does it mention anywhere positioning the cursor at a certain point on the screen?
c) Yes, you can do it on the PC but the mainframe is NOT a PC.
d) Why do you want to do this?
e) Use ISPF panels if you want to do full screen work with Rexx
