- When I first read this, I wondered why Peggy would want to do this,
- but then I thought a bit and remembered that if you really want to
- lock terminals into opac, you have to mess with the TCT anyway
- (to set the TRANSID so that the terminal will come up in OPAC
- initially), so using the OPERID=#$# to disable the stop command
- still makes sense. Although we use NSYS terminal control to do it,
- here's how you could do it using the opac user exit, LPC900P, as
- someone already mentioned:
-
- 013496 PROCCLR DS 0H
- 013497 ST R14,DSR14LV1 SAVE RETURN REGISTER
- 013498 EXEC CICS ASSIGN OPID(DSOPID)
- 013499 CLC DSOPID,=CL3'#$#' LOCKED?
- 013500 BNE PCLREX NO, CONTINUE
- 013516 MVC OPACUTRN,OPACUOTR YES, SET FOR OPAC RESTART
- 013520 PCLREX DS 0H EXIT POINT
- 013521 L R14,DSR14LV1 RESTORE RETURN REGISTER
- 013522 BR R14 RETURN
- Lines 13498-13516 are added. Also, in the dynamic storage area you need:
-
- 008700 ***********************************************************************
- 008800 * *
- 008900 * USER DYNAMIC STORAGE AREA *
- 009000 * *
- 009100 ***********************************************************************
- 009200 SPACE 1
- 009210 DSOPID DS CL3 OPERATOR ID FROM EXEC ASSIGN
- 009300 * SUB-ROUTINE LINKAGE STACK.
- Line 9210 is added.
-
- Hope this helps.
