JCL: Sysin DD* and SYSIN DD DATA

Here is JCL SYSIN card with DD* and DD DATA. in DD*, you can’t pass special characters, but in DD DATA you can pass. How this is possible, I have explained here.

How to Write SYSIN in JCL

In Jcl Sysin card is very popular. We can pass data from jcl to COBOL program using SYSIN.

//sysin dd *
 abc
 /*

In the COBOL program, you can accept the data as below:

ACCEPT ABCD-1 from SYSIN. 

So the data in SYSIN is pulled into ABCD-1.

How to Pass Special Characters in SYSIN DD DATA

But in DD* you can not give special chars like /*

//SYSIN DD DATA, ddl="ABC'
 /*
 ABC

We can give special chars in DD DATA. Here ‘/*’ is input.
