It's actually the assembler that deals with the CPU registers.

This is from CODESOURCERY\SOURCE\BINUTILS-2.17\GAS\config\tc-m68k.c(3029):

	    case FLASHBAR:
	    case RAMBAR0:
	      tmpreg = 0xC04;
	      break;
	    case RAMBAR:
	    case RAMBAR1:
	      tmpreg = 0xC05;
	      break;

So you can see that RAMBAR0 is also known as FLASHBAR (at least in this version of the source) :)

Paul.

Thanks for your answerer. What about RAMBAR0 :-). I must say I am a bit surprised to finde these built into the compiler. I expected to find such things defined in some header file. I'll try your suggestions.
