RE: Save file exclusively locked when displaying?

A save file has the same format as a tape file, (a file with no member) so
you could write a program to read it if so inclined. I've done it in the
past (although it's been a while and I used Linux) to figure out why saves
did not work properly. Now it's just easier to let IBM support figure it
out.

You cannot read and update individual "records" in a save file; it can

sort of "atomic" operation. If you have ever canceled a SAVOBJ
command and tried to display an "incomplete" save file, you will get
errors.

Actually, if I remember right, that's not *entirely* true: digging into a
save file, record-by-record, is part of how Dave McKenzie's UNDEL2 (a
customized version of which has been incorporated into our QuestView
product) does its magic.

It would, however, take me the better part of the day to refamiliarize
myself with the details.
