Chandra,
To determine the Operating System product number and version/release
level, under program control, you should use the Retrieve Product
Information (QSZRTVPR) API. The following sample when run on V4R3
returns (among other things) 5769SS1 and V4R3M0 for Product ID and
Release level respectively.
PGM
DCL &RCVVAR *CHAR 256
CALL QSZRTVPR (&RCVVAR x'00000100' 'PRDR0100' +
'*OPSYS *CUR 0000*CODE ' x'00000000')
ENDPGM
The API is documented in the Software Product APIs chapter of the
System API Reference.
