There is no way to clear the screen using REXX only.
You can, however, code a tiny Assembler program, something like this (taken from Google Groups):
| Code: |
CLS CSECT
CLS RMODE ANY
STLINENO LINE=1,CLEAR=YES
BR 14
END

There are many flavours of calling load modules from within REXX. Please refer to the fine manuals.

Please clarify what do you mean by "not able to use the assembler program"... As far as I know, Assembler is available in all Z/os versions...

Hi,
I am using the code CLRSCRN in my REXX script here. It does clear the screen before displaying any messages from the script. I don't think this code is shop specific also.
Can you please try tthe same and let us know?
Regards,
Manikant |

CLRSCRN used (many, many years ago) to be for REXX under VM only.
If it's now supported under TSO I am one happy camper!
(Makes note to su** it and see next time he gets hold of a TSO session!)
Cheers! |

Thanks,

not working on all/for all.
was wondering - since its a pgm,
any chance to find it in any IBM db or get the member or ..
source code or something?
legally of-course,
where would one look for this magic of a pgm? |

Doug Nadel wrote this one, which is ISPF aware:
| Code: |
ISPCLEAR CSECT , ISPF aware clear screen module
ISPCLEAR AMODE 31
ISPCLEAR RMODE 24
STM 14,12,12(13)
LR 12,15
USING ISPCLEAR,12
LA 15,SAVEAREA
ST 15,8(13)
ST 13,4(15)
LR 13,15
STFSMODE INITIAL=YES Initialize full screen mode
TPUT CLR,L'CLR,FULLSCR,,HOLD Clear the screen
STLINENO LINE=1 Clear screen & set cursor to line 1
STFSMODE OFF Go back to line mode
STTMPMD OFF Let session manager play with us
TCLEARQ INPUT Clear input queue
L 15,=V(ISPQRY) Load ISPF environment test address
BALR 14,15 See if ISPF is available
LTR 15,15
BNZ NOISPF If not, go to exit
L 15,=V(ISPLINK) Load ISPLINK interface address
LA 1,ISPPARMS ISPLINK CONTROL DISPLAY REFRESH
BALR 14,15 To force screen refresh on return
NOISPF L 13,4(13)
LM 14,12,12(13)
XR 15,15 Always return a zero return code
BR 14
SAVEAREA DS 9D
ISPPARMS DC A(CONTROL),A(DISPLAY),A(REFRESH+X'80000000')

DISPLAY DC CL8'DISPLAY '
REFRESH DC CL8'REFRESH '
CLR DC X'401140403C40400013'

END ISPCLEAR |
Rename it to whatever you fancy, or create a bunch of ALIAS'es |

| When ISPF aware clear screen module invoked via REXX from ISPF it show '***' and waiting for <Enter> before cleanup the screen... Is it possible just to cleanup without extra actions? |

CONTROL DISPLAY REFRESH
Specifies that the entire screen image is to be rewritten when the next ISPF-generated full-screen write is issued to the terminal. This facility should be used before or after invoking any program that uses non-ISPF services for generating full-screen output. |
