Reply with quote

Hello all,

I'm trying to get a report about actual storage groups on the system. I'm using rexx and a simple table to access into ismf. Works fine for volume listing but not for sg's. When I start the rexx in batch it's looping and printing out thousands of
"ISPF screen input error - code = 22"

I already tried to put trace i to my rexx but it doesn't tell me too much. Do somebody knows how to get the ISPF trace working?
I'm trying it with

Code:
ISPSTART CMD(VAOMISG2 SGXXXL SGXXXX) TRACEX NEWAPPL(DGT) +
BATSCRW(132) BATSCRD(27) BREDIMAX(3) BDISPMAX(999)


and

Code:
//ISPLOG  DD SYSOUT=*,DCB=(LRECL=125,BLKSIZE=129,RECFM=VA)


but it doesn't print out anything.


Thanks all

terminal I/O error codes 22 means Input stream size is greater than input buffer size or 0.

You do not have an ISPF screen in batch. Your rexx program can call many ISPF services, but cannot actually do a DISPLAY or similar because there is no screen.

Actually it can call ISPEXEC DISPLAY in batch but the display is simulated and acts as if the ENTER key was pressed. That is the reason for most ISPF problems in batch and why increasing BDISPMAX() does not help ... an error occurs, ISPF throws up a virtual error panel and press the virtual ENTER key which then redisplays the same panel which gets a virtual enter key which displays the same ... and so on. You can use DISPLAY if you must count on panel logic, for example.

But are you running this in batch or is the ISPLOG you mentioned in your logon proc? There is a very extensive trace (command TSO ISPVCALL in foreground, ddname ISPTRACE to dummy in batch) but that is probably not what you want. A little more detail on what you are doing is needed.

update: actually ISPVCALL might be OK for you... TSO ISPVCALL, run your program, TSO ISPVCALL again and look for >MSG in column 1. That shows all the messages ISPF creates, both internal and external. ISPVCALL doc
