[James Murray]

Sean,
Thanks for reviewing my submission. Good to have someone else who
is familar with the XGATE reviewing it. It does indeed appear that I
have omitted some of the alias instructions (com, cpc, ldw, mov, neg,
tst) and will add them. (In my application code I've used the base
opcodes these alias to.)

I could do with seeing your source code for bhs and blo as they work for
me. I'll contact you offlist to continue the discussion.

label1:

    bhs label1
    blo label1

003fc028 <label1>:
  3fc034:	21 f9       	bcc 0x3fc028 <label1>
  3fc036:	23 f8       	bcs 0x3fc028 <label1>

The datasheet says:
BHS (Same as BCC)
BLO (Same as BCS)

regards

James
