How does one access a variable from the asm command.  This example does 
not want to link.

	asm ( " .. code ..
		cmpw _cvariable, %%ax
		jz not_set
                .. mode code ..
	      "
	      : /* No Outputs */
	      : "a" (x) ...
	    );

I have used us all the registers available, and needed to compare the 
contents of '_cvariable' to ax.

Thanks

Vince
