Phil:
One system I worked on *ASSUMED* all positive numbers (it was a bank
savings system) so the assumption (reasonable) was positive. Not sure
about other systems.

Suppose you have values that you're converting between character

middleman, so you don't know what the application is going to be
using the values for.
For a non-negative value, packed decimal could be either positive
or unsigned.
What do folks usually do? Is it normal for code to actually care?
That is, if we say "Heck with it, we can't tell, so we'll just mark
it positive", is that likely to cause problems? Or is use of
unsigned rare enough that this is essentially a non-issue? (Hint:
I'd like that last to be the case!) Obviously a "sign=" value could
be passed around with the value, but that kind of metadata isn't in
the stream now, so I'd rather not add it.
Any and all ideas gratefully accepted...
