Activity parameters:-

a) PGM :- this is a positional parameter which must be coded after Exec with one blank. This parameter indicates the name of the program/utility of IBM

b)PARM :-

there are two ways to pass data

method I : using PARM:- this is a keyword parameter at activity level must be coded with Exec operand after PGM parameter. This parameter allows max (100) characters . they consists of predefined text/system defined commands.

The PARM parameter can be used to pass data to user/system defined programs

To receive PARM parameter data, Cobol peg, must be coded with “PROCEDURE DIVISION USING PARAMETERS” option. These parameters must be declared in the linkage section.

JCL:

// step001 exec PGM=cob001, PARM=”2004-10-10 date”(max 100 characters, no separator is coded and size in cobol is only the separator)

Cobol:

DD

Linkage section

01 x pic x(10). 01 y pic x(10)

d division using x,y.

1001-para

display x,y -à date 2004-10-10

stop run

method II :-

SYSIN DD * :-

SYSIN is a system defined DD name and * is the positional parameter off DD. This is used to pass data to Cobol peg/ to pass system defied commands to system defied pegs.

SYSIN DD * INSTREAM data must always be terminated with   /*

Any number of records/data/character must be declared in W S S

One row in SYSIN DD * is equivoque to one accept statement

JCL :

//step001 Exec PGM=cob001

//sysin DD *

[2004-10-10

………….

………….]

/*

//(terminator/end if JCL)

cobol:-

W.S.S

01 ws=data1 pic x(10)

01 ws=data2 pic x(10)

P D

1000-para

            accept ws-data1

            accept ws=data2

 
(* if accept coded in cobol then SYSIN DD * must be coded in JCL

* if SYSIN DD * coded it is not mandatory to coded accept ).

CA 7:- (computer associates )

This tool/package can be used to schedule jobs or can be used to submitting/organizing the jobs or can be used to cancel the jobs.

This is again a setup consists of panels which in thus provides difficult options for submitting the jobs, for organizing the jobs and for cancellation of jobs also.
