Re: Retrieving member names

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Loyd,

I would probably use chkobj to support everything but *last.   If *last is 
going to be used frequently, you could list the member to a user space using 
the list members API QUSLMBR.  That API is fairly strait forward and you will 
probably find it useful in other situations.  With RPGIV and pointers it would 
be very fast.  You could use the MBRD0100 format which only returns the member 
names.  The number of elements could be used from the heading area of the user 
space to calculate the location of the last member directly.  If you decide to 
support other formats, be aware that the MBRD0300 format is a little different 
than the most of the other list API's because you can't calculate the offset to 
the member information directly from the heading information.

One advantage of creating a wrapper around this API is that you can use it as a 
base for any of the other list APIs.

In CL, how do I retrieve a list of database member names? I'm creating a
command that uses members, and I'm trying to determine whether the
member exists. The hitch is I'm allowing *FIRST or *LAST for the member
name, but CHKOBJ doesn't allow *LAST as a member parameter. So, do I use
CHKOBJ or is there another way?

Thanks,
