  It's a macro. IFGT = if greater than = if greater than zero: true. It is
conditional assembly (probably). Otherwise it expands to the appropriate
run time instructions.

  bhs = bhis = bcc = branch if higher or same, unsigned, or branch if 
carry clear.

I've used Lattice asm, Devpac-2, CAPE, and Adapt. I don't have Macro68,
but it does support the new Motorola Standard syntax, which may lend
to confusion.
