Answer Posted / anjaneyulu javisetty
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.

I want to JCL sort for Non-COMP and COMP-3 fields SORT FIELDS=(1,5,A,6,11,A,12,11,A,19,1,A,20,1,A),FORMAT=BI,EQUALS Length of comp bytes is 11 bytes which start at 6byte and 12 byte considering 11 bytes in comp-3 is 6 bytes. Can anyone tell if the above sort work SORT FIELDS=(1,5,A,6,6,A,12,6,A,19,1,A,20,1,A),FORMAT=BI,EQUALS does not works OK
