JOBLIB DD DSN=LIB1,DISP=SHR
JOBLIB1 DD DSN=LIB2,DISP=SHR
EXEC PGM=COMPARE
JOBCAT2 DD DSN=LIB3,DISP=SHR
JOBSRC4 DD DSN=LIB4,DISP=SHR
JOBPGM3 DD DSN=LIB5,DISP=SHR

Refering to the sample code above, in which dataset will the system first look for
the program COMPARE?

1.LIB1
2.LIB2
3.LIB3
4.LIB4
5.LIB5

Plz help with answer?

Hi,

What do you think?

[Anuj Dhawan]

Hi,

This is from Manuals, now think what should be the answer:

Program Search Order: The program search order for MVS uses the following program libraries in the order given:
1) JOB Pack Area (already loaded programs)
2) Private task library, if specified.
3) STEPLIB library, if specified.
4) JOBLIB library, if specified, AND no STEPLIB is specified
5) Link Pack Area (PLPA)
6) System Link List (i.e., SYS1.LINKLIB and the data sets concatenated to it).

LIB1 is the answer? correct?

[Anuj Dhawan]

No, that's not correct. Answer is LIB3.

JOBLIB is searched only if STEPLIB(s) is(are) not defined. If STEPLIBs are defined, first library in the concatenation will be searched first.

Thanks Anuj,

It would be more useful, if u could provide more justification for that answer.

Thanks.

Hi Ghilli,

You are welcome . . . .

I'm not sure, what are you looking for when you say:

It would be more useful, if u could provide more justification for that answer.

What part of this, from m y previous reply

JOBLIB is searched only if STEPLIB(s) is(are) not defined. If STEPLIBs are defined, first library in the concatenation will be searched first.

is not clear to you?

[Anuj Dhawan]

Hi,

Manual says (the other one . . . ):

The system searches for a program in the private library you identify. If a job contains a JOBLIB DD statement and a step contains a STEPLIB DD statement, the system searches for the step's program first in the STEPLIB library and then in the system libraries. The system ignores the JOBLIB library for that step.

Hi again,

Try this:

1. Allocate a dataset to be used as JOBLIB.
2. Aallocate a dataset to be used as STEPLIB.

Assemble and link into the JOBLIB dataset and not in STEPLIB and SUBmit the JCL -- you'll get abend S806 which means load module not found . . .. This should calrify your doubt(s).
