Subject: UNARC and location 3EH

Subject: UNARC revisited
My thanks were slightly premature! ON my return home I have discovered that
my eyesight is not failing, nor is my brain, and UNARC will not extract!
A good dose of Z8E has solved the problem, but not explained it. UNARC is
sensitive to the value of location 3E. If that is zero (it is on my machines)
then the help info and the action of the program is adjusted to stop
file extraction! UNARC will now work OK if I precede it (in an alias) by a
swift poke of this location. NOW - why is UNARC checking this location?
My CP/M documentation says 'NOt currently used, reserved'. Is this another
form of 'wheel' byte used by BYE or some such program?
