The LeapYear

[Andy Dee]

For testing the speed of the routines, I wrote a little benchmark programm, calculating the given years in your code each 65535 times with my Basic- ans your Inline-Asm-code.

The Julian routine in PB is relatively fast, in contrast to the Gregorean, where Asm shows its power to BASIC!
