Re: MCH3402 Can it be avoided ?

[Reeve <rfritchman@xxxxxxxxx>]

I think there’s another explanation and perhaps a Big Brain on the list can
help us out.

I think this error is posted when the system goes looking for additional
pages of the program.  My guess is that the system saves the address of the
object when loaded and uses that address to fetch additional pages.  When a
new object replaces the old one, the old addresses are marked as free or
overlaid.  In either case, the attempt to fetch additional pages fails and
we get MCH3402.

I’ve been struggling with this annoyance for decades.  My build procedure
archives old objects before the compile starts and I still get stung,
particularly on service programs.

Remember 1978’s “System/38 Technical Developments” publication?  Sure would
be interesting to see that content updated—I like knowing how things work
under the covers.  It’s a lot better than guessing.
