Drew,
What about "Currency", which is what I am using in this program.  That can
have minus and plus(es)?

VB/VBA shouldn't have this problem.  A long Integer is 'signed', but there
is no -0.  Here's the def of a Long Integer from the MSDN:

Long (long integer) variables are stored as signed 32-bit (4-byte) numbers
ranging in value from -2,147,483,648 to 2,147,483,647.

Note that the absolute value of the negative number is 1 more then the
positive number?  If it was -2,147,483,647 to 2,147,483,647, then there
could be a negative zero.

Wow!  Is this a candidate for your subtle bugs or what?

I never knew that and I bet not many other people did either.

Thinking about it, I actually have this problem on our Daily Cash Book entry
system - I will revisit it with this in mind.

Gosh, I learno soooo much from this list.

Actually that was one of my first columns. It had this message box that said
"The balance is not zero. The balance is 0.00". It all came about because if
you put in a credit (minus) value first, the result would be minus zero.
Simple enough to fix with ABS(), but until then I didn't realize that there
were two values for zero.
