Apologies. The 'history' program that I just posted (and which is
probably now uneconomical to cancel) has a small problem in the source
that makes the .com file (when recompiled) about 4K larger than it
needs to be. The following fixes make it use the 7.7K that I
advertised.
The reason I made this mistake is because I:
(1) Updated the archive.
(2) Made some changes.
(3) Compiled.
(4) Made some more changes which I didn't like.
(5) Reverted to the copy of the source from (1).
I was then in the situation of having a newer object file that WASN'T
compiled from the existing source. Let this be a lesson to me!
