Excellent demo file, Dave. I think you've illustrated just about
everything a first-time user of relocatable code needs to see in a
very comprehensible form. I knew somebody had created such a file; I
just couldn't remember who it was. :=)

The only thing that isn't obvious is why you would use 'lgoto' for the
jump back to the label 'begin' in the main file. (Obviously, since
you've just returned from an external routine, you need to get PCLATH
pointed back to the current page but a beginner wouldn't necessarily
realize that.) Using lgoto there could confuse a beginner into
thinking that call's and goto's always need to be done using lcall and
lgoto.

You might want to consider putting a 'pagesel $+1' line after the
subroutine calls. Adding that line would allow the jump back to
'begin' to be coded with a regular goto rather than the lgoto.
