Lovelady's API Samples

RTVJOBINF

// Demonstrates use of QUSRJOBI to retrieve long library list.  Format JOBI0750 is used.



      * Retrieves the current job's library list, then prints each library name, along

      * with an identification of placement within the library list (System, Product,

      * Current, User)

This page is devoted to examples that demonstrate how to call certain IBM APIs from ILE-RPG on iSeries (System i, AS/400 or whatever its name is this week). Generally, any programs and/or snippets placed here are not intended to be plug-in solutions for whatever current problem, but are rather intended as a how-to by example. My hope is that some will benefit from these and will be able to roll their own improvements.

List of examples:

crtusrspc Create a user space, make it extendable, and return pointer
RTVJOBINF Demonstrates use of QUSRJOBI to retrieve long library list. Format JOBI0750 is used.
qjob Demonstrates use of QUSLJOB with the JOBL0200 format (to return select list of fields)
