Neither the J nor the Cs have any significance; jccccccc is just a variable name , as is nn. I probably would have used the name ddname, but that's only six characters.

PROCnn or Jccccccc names a concatenation that can be selected as the procedure library concatenation for a job, as specified by JOBCLASS(v), JOBCLASS(STC), JOBCLASS(TSU) or /*JOBPARM PROCLIB=ddname. You need to look at the JES2 JCL, any PROCLIB(foo) statement in the initialization member and any subsequent commands, e.g., $ADD PROCLIB, to see what is in each concatenation. -- Shmuel (Seymour J.)

It allows you to specify procedure libraries for different job classes. In the JES2 procedure, one DD statement must be named PROC00. If you specify additional procedure libraries (jccccccc or 01-99), then you might associate these libraries to a job class by replacing the jccccccc or nn of this parameter with the appropriate procedure library name or number. All cataloged procedure libraries to be used by jobs, time-sharing users, or system tasks must be defined in the JES2 procedure. z/OS 2.5 ________________________________ From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on behalf of Seymour J Metz <sme...@gmu.edu> Sent: Monday, February 28, 2022 5:09 PM To: IBM-MAIN@LISTSERV.UA.EDU <IBM-MAIN@LISTSERV.UA.EDU> Subject: Re: JES2, meaning of parameter value codes Please post example and release level. -- Shmuel (Seymour J.)

There are examples job parameters with codes such as "jxxxxxxx" and "jccccccc". I can't seem to find a table of their meanings. Can someone point me in the right direction?
