I have been using these programs sporadically for the last month on an
IBM-PC w/one DSDD and one Seagate 20 mb HD and 2mb JRAM3 card.  Mapmem
runs with no problem.  Does it cause the same kind of intermittent
errors if you run it off a floppy vs your HD?  Unless the HD is meant
for portable use, moving the computer around could disturb the write-
head/track dimensional alignment.  Suggest you copy mapmem to another
HD subdirectory and to a floppy and see if running it from them causes
the same error.  It sounds like some write/read problem is occuring
where mapmem is on your HD.
