SYSTSIN DD DSN=IMSP.SYSINLIB(DSNTEP2),DISP=SHR
SYSIN DD DSN=SSCHD.PMSTN.SYSIN(CFROWLOC),DISP=SHR

Hi,

SYSTSIN is the standard input DD (i.e. Terminal Input) for either the TSO program (IJKEFT**) or the REXX interpreter (IRXJCL).

SYSIN is a standard input DD, usually used to supply run-time parameters to the associated program.

Anuj,

From your reply I grasped that SYSTSIN gets the input from the terminal i.e. during the online process, is my understanding correct, please clarify.
Thanx in advance..

Not quite. . . SYSTSIN provides the "terminal input" to a batch process, not an online process.
