Rick, What you are missing is that the code generated by the C part make certain assumptions about register usage, and expect certain registers to contain, for example, pointers to data hunks. The assembly is required because the routine will be called from somewhere external to the program. Now if indeed you could code it with the asm in two separate modules, and the C part in its own module, that's fine, and my only argument for the necessity of inline asm will disappear. ie. you could call the function(s) by calling the asm, which would 'fall through' to the C, and then to the other asm module. I invited Ben to show me a better way, and his only comment was that it was obvious that the module should be entirely coded in asm, for 'obvious' reasons. -larry
