Our site has a TSO CLEAR command that "clears the 3270 display screen and places the cursor at row1, column 1". The site documentation says "The CLEAR TSO command processor is provided from the SHARE tape.".
CLEAR may be an alias for another program name. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Charles Mills Sent: Wednesday, June 17, 2026 5:16 PM To: [email protected] Subject: Two TSO terminal I/O from Rexx questions 1. If one were writing a Rexx exec to run in an interactive TSO environment, what would be the best way to clear the screen and make the next SAY write to the first line of the screen? Calling out to a user-written assembler routine that used the STLINENO macro? Or ... ? 2. From a Rexx exec running in interactive TSO, what would be the best way to determine the number of lines on the terminal? Basically the number of SAYs that one could do before the user received a *** prompt? Any related considerations?
