This may be like the off-label usage of drugs in the US (using an anti-cancer drug to treat arthritis for example). A branch of IBM other than the component owning division may well have recommended use for non-load modules because they did testing and found it worked and did good things. Unfortunately, IBM like many other organizations (including families) does not always talk to IBM so the expanded usage has not been formally recognized. I suspect the alternative uses need to formalized. >CC > >On Tue, Sep 8, 2009 at 8:45 PM, Ron Hawkins ><ron.hawkins1...@sbcglobal.net>wrote: > >> Chris, >> >> I believe you are right.
