Something is weird here.  Are you saying that pressing the / key while
in ALG entry mode in the command line actually echoes the characters
"/()" to the command line?  If so, it sounds like an internal flag
used by the EquationWriter has been set by mysterious means.  Try
turning the EquationWriter on then off and see if the parentheses
go away.  Your description of various user flags being set makes it
sound like some trauma has turned on some random bits in RAM, in which
case other things (like global variables) might be suspect.
If you can archive to a PC or RAM card, do so.  Then poke around
and look at your variables to make sure they're OK (if you can
EDIT them, they're fine).  You can also do an ON-A-F reset and choose
YES to recover RAM.

Tell us what you find!
