Actually, I don't think that's what I'm after having read the code more. I'm really after the ability of having the patterns as single lines, in your example MyVAR[0] would contain all the steps of the pattern, and not the first step.

eg:
MyVAR[0] = "129, 66, 36, 24, 36, 66,129" would send decimal 129 to PORTB, then 66, then 36 and so on, then repeat this pattern over and over again.

If I understand your suggestion correcly, it would be the same as having
MyVar[0] = "129"
MyVar[1] = "66"
etc

Any comments ?
