Hi all.  I have a PowerBuilder 10 application where I need to add some security edits for passwords that users create.  I need to verify that the passwords have X number of alpha characters and Y number of numeric characters. Right now the only validation I have is that the password must be more than 4 characters long.   I am thinking I will need to get the length of the password and then loop through to count the characters.  Does anyone out there have any examples I could use?
Any help would be apprecieated.
