So it's not a matter of allocating the memory; that's already being done in the calling program. The issue is accessing it. Somebody mentioned pointers; can anybody point me to some information on how that's done from RPG?
Some of the IBM APIs work similarly. An example: QUSLJOBS (list jobs) loads up a userspace with variably configured date. The first x bytes are header data, which contain the information used to access the detail data. The data is all in a user space, but there really isn't any difference between data in a user space and data in a contiguous stretch of heap storage; both can be accessed using pointer based variables. A *very* simple example of processing information returned by the QUSLJOBS API can be found at: http://pando.org/downloads/cp0300r.txt HTH, Chris -- chris@xxxxxxxxx www.brilligware.com Home of MineSweeper5250
