APPC (LUTYPE6.2) single session terminal

A single TYPE=SYSTEM macro is used:
DFHTCT TYPE=SYSTEM,SYSIDNT=ssss,ACCMETH=VTAM,TRMTYPE=LUTYPE62,
       FEATURE=SINGLE,MODENAM=mmmmmmmm
DFHCSDUP MIGRATE produces a CONNECTION definition and a SESSIONS definition:
DEFINE CONNECTION(ssss) ACCESSMETHOD(VTAM) PROTOCOL(APPC)
       SINGLESESS(YES)
 
DEFINE SESSIONS(xxxxxxx)  CONNECTION(ssss) PROTOCOL(APPC)
       MODENAME(mmmmmmmm) MAXIMUM(1,0)
The SESSIONS name xxxxxxxx is derived from the old SYSIDNT value concatenated with a 3-character identifier generated using a similar algorithm to the old macro. For example, for SYSIDNT=SYS1:
1st definition: gives SESSIONS(SYS1AAC) (starting count)
2nd definition: gives SESSIONS(SYS1AAF) ...

The MODENAME name mmmmmmmm is the macro MODENAM value.

You cannot autoinstall these CONNECTION and SESSIONS definitions. If you want to use autoinstall for your APPC single session terminals, you must redefine them as TERMINALs referencing a TYPETERM with DEVICE(APPC) (see APPC (LUTYPE6.2) single session terminal).
