When definining subs that could have multiple parameters, you need to do it like this:

GO_FORWARD      SUB    0, 1

Then check and pick-up any paramters before doing anything else in you sub -- otherwise the internal variables that carry parameters (__PARAMx) could get clobbered.

GO_FORWARD:
  IF __PARAMCNT = 1 THEN
    temp1 = __PARAM1
  ELSE
    temp1 = 1
  ENDIF
  servo1 = 75
  servo2 = 200
  IF temp1 > 0 THEN
    PAUSE temp1 * 250
  ENDIF
  RETURN
