No problem. Follow my suggestion earlier. Use a command exit program to
intercept CRTDEVDSP and change the parameter 3197 to something else. Even
the HMC session that is limited to 24x80 uses a 3179-2 and not a 3197.
If you create a "new" 24x80 session on your development machine using
autocreate does it make a 3179 or a 3197? If it makes a 3179 then delete
all existing 3197's on both your source and target and that should work.
The problem is that you're coming from a 3197 so it uses a 3197 and cannot
do PCO type stuff. Last time I made 3197 sessions was when I really had
3197's and autocreate off and wanted STRPASTHR to be able to match. IOW,
a BAMF long time ago.
