Hi,
Your array code seems OK to me, like:
Code:
myArray VAR Word[3]  'Create an array of 3 words.
i VAR byte

For i = 0 to 2
  myArray[i] = 12345  'Store the value 12345 in array locations 0, 1, and 2
NEXT
The absolute easiest way to get started with interrupts is to use Darrels Instant Interrupt routines, they're available on his website. Have a look at the "timer template" - that might be a good starting point for your application.
