We can pass data from JCL to Cobol in 3 ways.
1. SYSIN: Normally and using files
2. Parm Parameter in Exec stmt


1. Sysin: Using this we can pass large amount of data. The
data passed using sysin will be accepted in cobol using
accept statement in procedure division.

//sysin dd *
adbcde
/*

or

//sysind dd dsn=<filename>,disp=shr

2. Parm: The parm parameter in Exec is used to send 100
char's of data from jcl step to cobol. This is accepted in
cobol usign linkage section. LInkage section should be
coded with Lenght and data fields.

//Stepname exec pgm=<PGManme>,parm='100 chars max'

Hope this will give you a clear picture than the other 2
answers.
