Xy4 cloberring to EOF after series of changes

["Russ W. Urquhart" Russ.Urquhart@xxxxxxxx]

This may have already been resolved here, but i was wondering if anyone
could kind of explain what might have happended in my situation.

I am editing a 90K text file. Going thru and adding bold attributes to
selected pieces of text via a cva type command.

At one point, after having ok'd a replacement, the screen sort of flashed,
momentarily showing some garbage characters, but then returned to the point
that i started by changes. I assumed that it had found all it could, so i
then saved my document. Bad move. In paging forward, i found that it had put
a bunch of garbage from that point to the end of my file.

(Not all is lost and i think i can recover the original text) but i was just
curious as to what might have caused this, and what i might do to be more
cautious.

I was using a '486 machine running DOS and had loaded the U2 library (an
older version, not the latest.)


Thanks for any info!
