No rest for the wicked, John.

I always specify the size. Some assemblers can infer the size from
the operand, but it's usually better practice to specify it.
The L suffix is not supported on the H8/300 variant used
by the RCX.

I'm pretty sure that the way the assembler will look at the non-comment
lines of source is that the first word delimited by white space is the
opcode, and the next bits are the operand...
On the other hand, I'm not sure why you want to do this. Most folks I know
that are writeing assembler for the RCX use their own editors and IDEs.
