waitpeq(%0100, %1100, 0) 'Wait for P3 & P2 to be low & high

I just wanted to know the proper syntax. Are the parentheses the only difference?

    I found a file on my computer named "pasm pulse measure". The first line is what I was looking for.
    ..  waitpeq pinA,pinA   'delta between 2 pulses
  mov temp1,cnt       '___-_______A
  waitpeq pinB,pinB   '______-____B
  mov temp2,cnt
  sub temp2,temp1

    The third argument in Spin was meant to cover a second bank of 32 pins in a device that never made it to production. In PASM, since there's no room in the instruction for a third argument, the plan was to signify which bank by the state of the carry flag, a really bad idea that I'm glad never saw the light of day.

    I really never fully understood what programmers meant by the term "arguments". Thanks for clearing that up.
