What ever libraries you need for the program to run you have supply in JOBLIB. If you want datasets to be used in a particular step supply them in STEPLIB . STEPLIB takes precedence over JOBLIB. JCLLIB is used to change the default proc lib to some other proc lib. as in the below given statement.
//PROCLIST JCLLIB ORDER=(xxxx.xxxx.xxx) This is useful when you are changing a proc in production and want to test it.

The joblib and steplib dd statements are used to specify alternate libraries where programs can be loaded from.
Joblib is used at the start of the jcl to specify an override library to use for the entire job it is placed immediately after the job statement and applies to the whole job.
Steplib is used in an individual step in the job it is placed immediately after the exec statement to which it applies and is used only for that step.
Jcllib and Proclib are used to specify where jcl is to be loaded from rather than programs.
Jcllib is used with the INCLUDE MEMBER statement to specify the library where pieces of jcl are held that can be included into a number of jobs. I have not seen this actually used, more often rather than separating out parts of job steps and including them it is more usual to extract out complete job steps into separate procedures stored in a proc library.
Proclib is the dd statement to override where to get procedures from. |

| Vijaya Baskar, there is no standard DD statement called PROCLIB. There is no standard JCL construct called PROCLIB. |
