RE: Library List question...

You are correct. It is just we use addlible as we run some CL and ovrdbf
to mbrs as well inside a CGI that also exist on the same lib. So for use
to run:

Addlible X
Open
Chain
Call CL1 parm(A B C)
Ovrdbf (x) (y) mbr(date0305)
write
Close 
Rmvlible x

Works for us better as we use some things back from CL call to submit
jobs to batch to run reports and email reports.
If that works for you it is just the same.  We just got in the habit of
having a subroutine that does the add and the rmv and we just call it as
needed.

Hi again,

Okay. You're suggesting doing the following, right?

      FCUSTMAS   IF   E           K DISK    USROPN

      D QCMDEXC         PR                  ExtPgm('QCMDEXC')
      D   command                  32702A   const options(*varsize)
      D   length                      15P 5 const
      D   igc                          3A   const options(*nopass)

      D cmd             s             30A   varying

      c     *Entry        plist
      c                   parm                    Library          10

      c                   eval      cmd = 'ADDLIBLE ' + Library
      c                   callp     QCMDEXC(cmd: %len(cmd))

      c                   open      CUSTMAS

      c                   eval      cmd = 'RMVLIBLE ' + Library
      c                   callp     QCMDEXC(cmd: %len(cmd))


My question is, why would you do that?  The following code works just as
well. It gives you all of the same advantages (and disadvantages) as
your library list solution, but is simpler code, performs better, and
doesn't need to muck with the library list at all?


      FCUSTMAS   IF   E           K DISK    USROPN
      F                                     EXTFILE(FileName)

      D FileName        s             21A

      c     *Entry        plist
      c                   parm                    Library          10

      c                   eval      FileName = %trimr(Library) +
'/CUSTMAS'
      c                   open      CUSTMAS

I'm trying to understand what the advantage of using a library list is?
If the program has to be aware of the library (regardless of whether it
gets this info from a constant in the program or whether it reads it
from a file, data area, parameter, etc) then why not just specify the
libraries explictly when opening the file?  What good is the library
list?
