Subject: 6502 coding request

Want a credit in the Host interface between BBC BASIC and the Commodore 
64 Kernal?

The C64 Kernal counts time in 1/60s of a second. I need to convert 
between that and counts of 1/100s of a second when read and set by TIME. 
Sub-second errors are acceptable, as long as multiples of 6 are 
converted to the same multiples of 10 (eg jiffy=60 becomes time=100) and 
vis versa.

\ Jiffy to Time
\ In,  &YYXXAA = Timer1 in 1/60s of a second
\ Out, Timer1 in 1/100s of a second
\      Will then be stored in (ptr),0-4

\ Time to Jiffy
\ In,  Timer1 in 1/100s of a second
\      Stored at (ptr),0-4
\ Out, &YYXXAA = Timer1 in 1/60s of a second
