Thanks for your help Two questions
Does BLDL or DESERV have anyway of differentiating between TASKLIB/STEPLIB/JOBLIB I think not. TCBJLIB represents the first library looked at be it TASK STEP or JOB Second is there anyway of getting the associated DSN name Thanks -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Peter Relson Sent: Sunday, December 01, 2013 1:36 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: DESERV function get DCB address >unfortunately DESERV >FUNC=GET needs a real DCB address as opposed to the zero used invoking BLDL You need to supply a DCB address that represents a concatenation in which the member for which you are seeking the directory entry exists. BLDL happens to support 0 as asking to search tasklib(s) steplib/joblib lnklst DESERV does not. TCBJLB of the jobstep program task is either joblib or steplib. TCBJLB of subtasks of that task, when different, is a tasklib. So where is the member? If it's in the lnklst, then use the DCB pointed to by CVTLINK. If you don't know where it is, then you may need to do what the system does to locate a module: search every tasklib up to/through the ASCBXTCB TCB using its DCB search the LNKLST using its DCB And if that's not where your member is, then you need to search where it is. In some situations, for example, ISPLLIB is used not as a tasklib. Of course it was not even stated why BLDL was being used. In some scenarios, it is necessary first to eliminate the possibility that the module is in LPA and not the LNKLST (perhaps by CSVQUERY).
