[Logic] How to create exprsn to flag a new grid square?

[Bill VanAlstyne]

One ought to be able to write an expression that would check to see if a
grid square number in the "GRID" field of the MAIN log entry screen is
"new" -- i.e., either hasn't been worked before or hasn't been confirmed. I
have my map to do this, of course, but it would be cool to get LOGic to do
it for me, especially in the "heat of battle".  :-)  I've had success in
researching FoxPro commands to write various other kinds of expressions, and
I know LOGic possesses the information I want, but I can't seem to gain a
mental foothold on this to get started. Could somebody give me an idea or
two?
