This list is just amazing, and I mean how great it is. So many different 
responses with such a variety. I thank each and everyone of you. 

To answer this reply, yes Buck,  I would be very grateful for your antique 
boilerplate. After all some antiques are priceless.

You won't need UIM, but you will need the list APIs.

Undoubtedly.  There are two approaches to writing your own WRKSPLF command
(for example.)  Wrap the IBM command in your own CL program or write all the
functionality yourself.

This is a silly example, but here is something to look at:

CMD  prompt('Our WRKSPLF shortcut')            
PARM kwd(USER) +                               
     type(*NAME) +                             
     len(10) +                                 
     dft(*RESTRICT) +                          
     choice('*RESTRICT, *CURRENT, user name') +
     spcval('*RESTRICT' '*CURRENT') +          
     prompt('User')                            

pgm &user                                                         
                                                                  
dcl &user    *char 10                                             
dcl &jobUser *char 10                                             
                                                                  
/* See if somebody should be restricted but slipped by */         
rtvjoba user(&jobUser)                                            
if (&jobUser *eq 'JOHNDOE') do                                    
  if (&user *ne '*RESTRICT') do                                   
    chgvar &user '*RESTRICT'                                      
  enddo                                                           
enddo                                                             
                                                                  
/* Restricted users can only see the splf's in their data area */ 
if (&user *eq '*RESTRICT') do                                     
  rtvjoba user(&jobUser)                                          
  rtvdtaara &jobUser &user                                        
enddo                                                             
                                                                  
QSYS/WRKSPLF select(&USER)                                        
       
endpgm 

Both sources are named WRKSPL.  When you compile the CMD, the defaults will
see to it that the command calls your CL program (prompt it to see what I
mean.)  If you exactly match the IBM command's parameter list, you can even
call your CL program WRKSPLF and have the IBM command call your CL...

This is not hard at all, and you can basically do anything you want in your
WRKSPL, whilst leaving the IBM functionality in place.  Just call WRKSPL
from your menu instead of WRKSPLF.  This is much easier than writing the
complete WRKSPLF functionality yourself.  If you're interested I can email
you an antique boilerplate for the QUSLSPL API.
