there are two ways to send data to the application prog.
1)parm (for small amount of data)
2)sysin(for large amount of data)

1)parm: is used to send the data to application prog
(eg;.cobol)

upto 100 characters.

2)sysin:is used to send the data to application prog
(eg;.cobol)

large amounts.
examples:

1) using JCL with sysin. //sysin dd *here u code the parameters(value) to pass in to cobol program /* and in program
you use accept variable name(one accept will read one row)/.another way.
2) in jcl using parm statement ex: in exec statement parm='whatever' in cobol pgm u have to code linkage section in that for first value you code length variable and variable name say, abc pic x(4).it will take john inside to read next value u have to code another variable in the same way above mentioned.
