I have implemented a clock synchronization algorithm on the
transputer network in Logical C. To set the timer, I need to insert
two transputer instructions in my C code:

	#pragma asm
	ldl time
	sttimer
	#pragma endasm

where "time" is the C variable which contains the desired value of the
clock. However, the tcx compiler will not compile "time" to its address
as in the C code, and thus tasm will not be able to recognize it. The 
way I get round this problem is really a big hack. I go pp and tcx,
and then I edit the .tal file and change "time" in the above 
instruction to its address manually before I assemble and link to
get the executable. I would like to know if there is a more elegant
way to do that in Logical C as what can be done by the Occam compiler.
