16-bit Unsigned AND on Commodore 64

I have a project that requires something beyond the default BASIC that’s available on the Commodore 8-bit computers. Actually, it’s several things.

• 16-bit AND for unsigned integers
• XOR
• Decimal to Hex
• Hex to Decimal

I can get two of these by utilizing Simon’s BASIC Cart: XOR and Hex to Decimal.

Today, we’re going to implement a 16-bit unsigned AND .

In Commodore 64 BASIC V2, the AND operator works with 16-bit signed integers (-32768 to +32767).
