Re: escaping in syntax strings

Yes --- the insns reference the regular hardeware for r13 directly (i.e. 
(reg h-gr 13) ). Probabloy what should have been done, and what you're 
expecting is that h-r13 should have a getter/setter pair that does this 
automatically.

FWIW, this is just an example of what Frank was pointing out. It's what 
I came up with at the time, probably because I hit the same $ problem as 
you did. I don't think that it's a better way than coding $ in the 
syntax string and handling it directly though.
