Hi James

Why ridiculous ?

TODAY exists LCD with 38XX pixels, if you use two of this monitors you can
have more of 7500 pixel.

For me, of ridicule alone if it is made that VFP returns a value that could have sense, in order to indicate a value that it does not have sense.
They could not use NULL or MAXINT ?
