  Hi Sid,
  
  To my opinion (and that of the Stamp manual :-): yes, that should work that way!
  
  Regards and success,

  If I write:
  
  DIRH = 1
  OUTH = 0
  
  will that make pins 8-15 outputs and set them all low?

  No, that will only make P8 go low. What you want to do is this:
  
  OUTH = %00000000
  DIRH = %11111111
  
  Using binary values when working with multiple IO pins helps "visualize" what's going on. Your code is doing this:
  
  DIRH = %00000001
  OUTH = %00000000
  
  ... so now you can see why only P8 is being made an output.
