hi all,
some questions
1.Diff bwtween JCL Lib and Proc lib?
2.Is there a way in JCL to identify the oldest GDG version assuming we don't know how many generations will exist at any given time?

JCLLIB is user defined catalog library
PROCLIB is predefined system library

Yes, yiou can refer as A.B.C(-1) to get the previous generation. |

| JCLLIB is a JCL stmt that allows the user to specify his own proclibs and/or specify the order in which they're searched to find the PROC(s) or INCLUDE libraries invoked in the JCL. You can use the ORDER clause to do this. You can specify private (user) or system libraries. |

hi dear
JCLlib is a library which is having catloged procedures which are defined by the users.
So bfor calling any catloged procedure u have to define JCLLIB path.
syntax is
//NAME JCLLIB ORDER='PATH'
CORRECT M IF I M WRONG

Hello,
For my $.02, i'd describe proclib and jcllib as follows:
PROCLIBs are Procedure Libraries. These may be system or user PROCLIBs. Typically, a site's PROCs are stored in one or more user-defined PROCLIB(s) - not a system PROCLIB.
In addition to the JCLLIB statement that allows library specification, "jcllib"s are one or more places to store execution jcl (production, test, someone's "own" personal library, etc). Many sites also have some jcllib(s) that are where scheduling software retrieves members for running schedlued jobs.
Also, to identify the oldest version in a gdg via jcl, you could run an IDCAMS step with a LISTCAT. Specifying -1 will get the previoius version (if one exists) but that may not be the oldest version. |

JCLLIB is a JCl keyword used for defining the Catalogued procedure
There is no such reserved word PROCLIB. Generally PROCLIB is used as label in the JCLLIB statement
//PROCLIB JCLLIB ORDER=DATASET NAME
Regarding getting the versions of GDG use IDCAMS LISTCAT command |

In JCLLIB we can define order stmt where u can define no of libraries which are seperated by comma.
so that system will search for that particular procedure in the sequence as specified in the order stmt.
