Marcus, try
*function ValidStr
lparameters str2check
local validchars,testchars
validchars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 "
testchars = space(len(validchars))
return len(alltrim(chrtran(str2check,validchars,testchars))) = 0
Using validchars as above ValidStr("Silvio") will return .F. while ValidStr(upper("Silvio")) will return .T:
Just adjust validchars to your needs
