Not a very courteous thing to do, but since you asked: >For example, a user is connect and i would watch your screen in ANY MOMENT. >Something exist in Assembler370 or REXX???.... You'd have to perform real I/O to the terminal in question and issue a "Read Buffer" command. Aside from the expected "God mode" privs, you'd have to get around the fact that CP sees the device as "in use". It would probably be more complicated for LDEVs, although they CAN BE ENABLED/DISABLED and ATTACHED/DETACHED. I don't see how to do it without zapping the RDEVBLOK, which will quickly bring down your system if the user tries to do I/O to the terminal while you're snooping. >Rodolfo. Gee... not much help.
