RE: How do I use QWCRSVAL API to retrieve QUSRLIBL?

[qsrvbas@xxxxxxxxxxxx (Tom Liotta)]

Tom:

I'm including a simple CL program that retrieves both QSYSLIBL and QUSRLIBL in 
a single call to QWCRSVAL. Although not written in RPG, it will actually 
translate easily; and in the meantime, it'll execute and provide a dump to give 
you something to compare against the documentation so you can see what the API 
is doing, particularly how to interpret the returned variable content.

Note that CL doesn't directly support binary integer variables, so those are 
declared as *char(4). You'll likely define them as 10U 0 instead. Also note 
that there is no error handling. I have no idea how you'll choose, so I'm just 
going the default route.

Hope it helps.

Test QWCRSVAL:

pgm

   dcl              &rcvvar      *char    999
   dcl              &lenrcvvar   *char      4
   dcl              &nbrsysval   *char      4
   dcl              &sysvalnam   *char     80
   dcl              &errcod      *char      8

   chgvar     %bin( &lenrcvvar )   ( 999 )
   chgvar     %bin( &nbrsysval )   ( 2 )
   chgvar           &sysvalnam     ( +
                                     'QSYSLIBL  '  *cat  +
                                     'QUSRLIBL  '        +
                                   )

   call       QWCRSVAL    ( +
                            &rcvvar     +
                            &lenrcvvar  +
                            &nbrsysval  +
                            &sysvalnam  +
                            &errcod     +
                          )
