In Jcl Sysin card is very popular. We can pass data from jcl to program.
//sysin dd *
In the program we can accept data as follows:
ACCEPT ABCD-1 from sysin.===> so the data in sysin is pulled into ABCD-1.
But in DD* we can not give special chars like /*
//SYSIN DD DATA, ddl=”ABC’
We can give special chars in DD DATA. Here ‘/*’ is input.
