I can see why you might need a reminder:)

"CP/AM (C) 1985 Applied Engineering LOADER & BIOS by Steven Malechek in 
1985. CCP & BDOS "RP/M" by Jack Dennon. Update to Ver R5.1.1S
by Steven 
Hirsch in 1986"

That is promising.

Sounds like an "Open As..." option to me:( A little messy but with a [x] 
checkbox for readonly even if and when editing is supported there is minimal 
risk. The other thing I was thinking is that maybe some kind of logic can be 
applied to determine the difference once the difference is understood...

Idle thoughts... thanks Steven.
