[quote="Jon Williams (Parallax)"]When defining subs that could have multiple parameters, you need to do it like this (note the comma):

GO_FORWARD      SUB    0, 1

Then check and pick-up any parameters before doing anything else in your 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[/quote]

Thanks Jon. This helps a lot. I am on the road in NJ with just my PowerBook. But to my recollection the example code shows some subroutines fpr DELAY and DELAYUS that shows   
[code]
DELAY SUB 1 2
[/code]

without the comma. (or I misread it! ... mea culpa!)

Also thanks for the routines you posted I am going to add them to the serial string handling routines as part of a 'standard include' file I am building.

When I get back early next week (my #1 son is gettin married tomorrow) look for some SX48 Robot code coming forth with IR sensing collison avoidance.
