The function is almost ready

strRegKey returns a 12 chars string, which is the registration code of my ebooks

The problem is that the last 3 chars are different form the asp string result

Each char of the string is composed by a loop in the for command

I cant not imagine what can be wrong, because it works almost fine

Maybe a VFP equivalent function do not work the same as the asp funcion ?

I would be glad if some one could take a look at the VFP code, now that it is almost ready
