JCLLIB - Gives the library for cataloged procedures
STEPLIB - Coded in the individual steps. It gives the
library where the program specified in the EXEC statement
for that particular step should be searched for.
JOBLIB - Coded after the JOB statement. It specifies the
library where all programs specified in the EXEC statements
of the entire JCL should be searched for.
Having both JOBLIB and STEPLIB, the STEPLIB will override
JOBLIB for that particular step where STEPLIB is given.
Having both JCLLIB and STEPLIB shouldnt have any co-
relation as one is concerned with cataloged procedures and
the other with the programs.
Please verify answer

Answer / vinay sonar

STEPLIB will take precidence over JOBLIB

Answer / ranbeer

If you code both a JOBLIB DD and STEPLIB DD statement in
the same job, the STEPLIB DD statement overrides the JOBLIB
statement only for that step. For that step only, the
system ignores JOBLIB and first searches the private
libraries specified on the STEPLIB DD statement. If the
system does not find the program in the private libraries,
it then searches the system libraries. Then, if z/OS still
has not found the program, the system abnormally ends the
job step.

I 've faced such situation where in the Load module is not in Steplib(private lib) but it was there in Joblib (system lib ) but still the job abends with load module not found issue S806 .

Answer / sreedhar naidu dhekodna

First STEPLIB will override the JCLLIB. If the required
module is found then the JOBLIB won't be considered or if
the required module is not found in STEPLIB librarie(s)
then again the job will search for module in JOBLIB as well.
