What is the difference between SYSIN and SYSTSIN. I checked a post where it is described as
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.
So, is it correct or is there anything else which is missing here... I was checking IBM manual where SYSTSIN was described as
The SYSTSIN DD statement is used to specify that the data to follow consists of executable commands and/or subcommands. For example, to indicate to the system that all data following this statement is to be used as input, until the system encounters an input delimiter, such as the characters /* or the DLM operand,
but we put commands in SYSIN as well..
Can anyone please clarify me..
