Ken:

Here is a synopsis of some research that I did last summer, with a link to
IBM's documentation.

By the way, the number of libraries in the library list was increased to 250
in V5R1.

Programs that use any of the following may need to be reviewed and revised
to handle the enhanced library list (250 libraries).



Objects affected:



·        The CL command RTVJOBA USRLIBL( )



·        OS/400 APIs affected:

·        QUSRJOBI (Retrieve Job Information)

·        QWCRTVCA (Retrieve Current Attributes)

·        QUSRSPLA (Retrieve Spool File Attributes)

·        QWDRJOBD (Retrieve Job Description)



See the following IBM link describing the library list changes:



http://www-919.ibm.com/servers/eserver/iseries/developer/os400/lib_list.html



Please note that IBM has allowed the option to artificially limit the user
library list to 25 libraries system-wide if the data area QUSRSYS/QLILMTLIBL
(which is shipped with the system) exists, but this will be ignored after
V5R2.  This means that eventually you will need to make the program changes
necessary to handle the user library list containing 250 libraries.
