>Sorry, here is the problem revised. It is to be a random character string, and it is based on the 35 characters 1-9, A-Z Uppercase only. So, can VFP do a random string generation?

lcString = ''
for lnI = 1 to 20
	lnNumber = int(rand() * 36)
	lcString = lcString + iif(lnNumber < 10, tran(lnNumber), chr(lnNumber + 55))
endfor
?lcString
