Hello

Not trying to be rude, but I don't need a example, because I also have a "ignored letters" i.e. "B,C" box and "ignored sets of letters" i.e. "FAG", "PMS"

I have all the code in thought, but I am worrying about the number / lenght of the processes, running out of memory ya know stuff like that

Thanks for the reply

>>Hello all

>>I am working on a letter incrementing utility AKA A,B,C but with a 7 character field AKA AAAAAAA, AAAAAAB, AAAAAAC. So this procedure could have to loop up to 8,031,810,176 times, yea thats 8 billion times

>>a. I should use a table to store the results, right?

>>b. I think I will have problems displaying the results, does anyone know if a object (Grid / Listbox / whatever) that can handle 8 billion records without a increased chance of my program or the PC bombing?
>>
>>c. Would a for/endfor statement bomb having to loop 8 billion times?

>>If anyone can think of any other issues they would be greatly appreciated
