Ok. I will go in that direction, but there is still one problem. My shop's default setting is STD. I still need to be able to switch them out of STD, then back when I am finished...

go to ISPF option 0 scroll down one page and use 1 as per my previous posts

whenever an option is customizable by each user it is not a standard any longer
the issue might be, on the other side to be able to logon, using a model5 logon mode table
unless vtam is setup to diiscover automatically the terminal model, and setup correctly the alternate screen size

Sorry, when I say 'I need to be able to switch them out of STD' I mean do it programmatically, not manually.

why do You want to deprive people of the added facilities of using DATA
when editing browsing lrecl 80 <things> nothing will change

I would not worry about the issue for more than a couple of seconds
worry about the application, and switching back and forth between data and std will be a last minute secondary detail

I dug through the PDS member (ISPSPROF) and I noticed that it looks like the format is <VARIABLE NAME> <VARIABLE VALUE>:

Code:
ZDEL    ..;.ZDEVNAM ...ZDTVOPT ..1.ZDTVWARN..0.ZENBLDMP..OFF.ZFAMPRT ..2.ZFMT
 ..D.ZFRAMIC ....ZGCOLORS.. 1234567.ZGGCOLRS..  01041302030600.ZGHCOLR ...ZGPCOL


I assumed the variable is ZFMT because I am in DATA mode. So then I tried this:

Code:
/* REXX */

ADDRESS ISPEXEC
'VGET ZFMT'

SAY ZFMT
ZFMT = 'S'

'VPUT ZFMT'


When I first ran it, it display 'D'. Then the next time it displayed 'S'. But it really did not change the 'Screen Format' field when I go back to Option 0. Is there something I need to do to actually make the change go into effect?

The application is complete. It works whenever I switch the Screen Format to DATA or MAX. It will display the CICS BMS map as a MOD2 or a MOD5.

I have never worked with stuff in ISPSPROF. I guess it is not supposed to be changed by the user. Also, ZFMT is not documented in Dialog Developer's Guide and Reference. You should realize that changing it from a program would not be supported by IBM. I recommend against it.

If you want to continue... ISPSPROF is a table. You should be able to get the row and modify it. By my observation, ZFMT is an extension variable in the first row. But there are a many extension variables that you probably need to preserve.

I do not have any experience with working with these tables. Can you use ISPF services like TBSCAN to read data? Also if you update a variable in the table, does it automatically take effect for the user?
