How do I validate a strong login password in Power Builder?

Question

I need to validate the below rules for my login password: Passwords should be a minimum of eight (8) characters and max 15 chars and it should contain the below in it:

• English upper case letters (e.g., A, B, C, ...Z)
• English lower case letters (e.g., a, b, c, ...z)
• Westernized Arabic numerals (e.g., 1, 1, 2, ...9)
• Non-alphanumeric ("special characters") (e.g., ?,!,%,$,#, etc)
• Enforces at least a minimum of four (4) changed characters when new passwords are changed.
• Prohibits password reuse for six (6) iterations prior to reuse.

Its challenging to address all these rules in a single regex. Please suggest a efficient working option.

I am using Appeon PowerBuilder 2022 R2.
