Hi all.
First of all - I'm a TOTAL newbie to this whole "z/os" thing, so my sincere apologies, in advance. (Like, srsly. day 3. at best.)
Second - If its already answered, I've missed it, and not on account of lack-of-trying, so again - sorry

I'm looking for the most efficient way to get a list of all members,
in a pds, thats NAME starts with wxyz.

Basically, I'm looking for the best way to "REXX serch wxyz* members".

Please and thank you,
RazVorox.

You can use IEBCOPY CP with Wildcards to get what's needed. Besides that, TSO command LISTDS <pds> MEMBERS will give a list of all Members in a PDS[E]. Apply some filters and that's it.
There are certainly more options than these samples.

What are you planning to do with the list of members?

Create an Index.
Basically, they are cbl progs listed by user prefix.
so, for example, mine would be rzvx0001, rzvx0002 etc.
I'm gonna parse them, then grab the "description" section from each,
and than create a basic index.
i.e.
rzvn0001 - Hello world
rzvn0002 - call time subroutine
..
etc.
its meant as an exercise in REXX to better familiarize myself with it.

Have a look at ISRSUPC using REXX (there was a discussion recently here). This makes it much easier as you get Member Name and Search String as result. Good luck.

Quick-and-dirty, if you only have a few members:
ISPF 3.2, enter dsname like LIB.CNTL(A*)
Then cut the list.

Thanks a lot Joerg!
Seems like I've got my starting point.
Gonna do some research/homework on the
IEBCOPY ; LISTDS ; ISRSUPC

Will(y) also try to rexx the 3.2 with the (*) member.

you can also use wildcard in ISPF 3.4, i.e. to browse you enter
b /(*list*)
in the line command

For the desired purpose, I would go with ISRSUPC. The only thing left is to apply some kind of filter for the member name.

Well, if you are going to use some kind of programming, then the ISPF library services can do he trick. Here is a small demo REXX:
Code:
/* rexx */                                                           
 mslmbr=''                                                           
 address ispexec                                                     
 "lminit dataid(did1) dataset('xxxx.lib.data') enq(shrw)"             
 if rc<>0 then say 'lminit rc' rc                                   
 else do                                                             
   "lmopen dataid("did1") option(input)"                             
   if rc<>0 then say 'lmopen rc' rc 'did' did1                       
   else do forever                                                   
     "lmmlist dataid("did1") member(mslmbr) option(list) stats(no)" 
     if rc<>0 then leave                                             
     if left(mslmbr,4)='TEST' then say  ' 'strip(mslmbr)             
   end                                                               
   "lmmlist dataid("did1") option(free)"                             
   "lmclose dataid("did1")"                                         
 end                                                                 
 "lmfree  dataid("did1")"

You can skip over earlier member names by starting with the name you want.
Code:

mslmbr = 'TEST"
. . .
    "lmmlist dataid("did1") member(mslmbr) option(list) stats(no)"
. . .


This works for RazVorox because the search is for the prefix of the name.

From the ISPF services guide:

When you invoke LMMLIST for the first time, member-var is used for selecting a starting position within the member list
