Need Clarification

[breentha_d]

Dear All,

Based on the example below which i saw in the tutorial session,

EXAMPLE JCL

Code: Select all

//MYJOB  JOB   (R345),'KRISHNA REDDY'
//STEP1  EXEC  PGM=COBPROG
//INFILE DD    DSN=TEST.GLOB.TEST.LIB,
// UNIT=SYSDA

It says:
In above example, COBPROG is executed, and a file INFILE which may reside on any of the devices which are grouped under the symbolic name SYSDA will be accessed.

I thought, the INFILE is the ddname, and the COBPROG should be in the LIB file and not in the INFILE, i am confused because i am very new to this. Pls explain to me this statement.

load libraries can be denoted as JOBLIB or STEPLIB in the reference name. otherwise, the reference name of a dd statement refers to a SELECTed file (in COBOL). any file that is referenced by the executing program (COBOL, ASM, PL1....) needs to have a dd statement in the job to allow for allocation by jes upon execution of the job.
