[comp.sys.xerox] Need method of determining whether unsaved changes exist

BRAND%KEGGER@CIRCUS.LLNL.GOV (Hal R Brand) (12/07/87)

With Lyric and the "problem of packages" I have found it quite convenient
to add a number of "commands". Two of these are LOGIN and LOGOUT. I would
now like to improve on my LOGOUT command to flag any attempt to (LOGOUT T)
with unsaved changes. IL:FILES? does this, but returns no values and I
would like to avoid calling IL:FILE? if unnecessary. However, I have been
unable to find any programmatic method of inquiring of the file package
if there are any unsaved changes (either functions/variables/etc. to be
assigned OR files with changes yet to be written). Can anybody help?
