Interrupt now OK with one time adjustable Hz.

Is their a way to change a Hz variable before each interrupt on?
wFREQ_Hz var word

Something like:

;--- Change these to match the desired interrupt frequency -------------------
;--- See http://DarrelTaylor.com/DT_INTS-14/TimerTemplate.html for more Info.
;@Freq = 10 ; Frequency of Interrupts in Hz
@Freq = wFREQ_Hz ; in assembly
