Hi Art,
I think this is what you're looking for:
Code:
ArrayElement.0[5] = 0    ' 6th bit in the firts byte
ArrayElement.0[12] = 1   ' 5th bit in the second byte

'And indexing...
For i = 0 to 24
  ArrayElement.0[i] = 1
NEXT
For more details see Melanies post here. Also see section 7.6 in the PBP3 manual - if that's what you've got.

/Henrik.
