I havn't used the linea stuff but use Megamax AL often.
You can access C variables 3 ways:

int extint;
func()
{
	register int regint;
	int intint;
asm {
	MOVE regint,...		/* access registers by name */
	MOVE intint(A6),...	/* local vars: name is offset from A6 */
	MOVE extint(A4),...	/* external vars: name is offset from A4 */
	DC.W 0xA001		/* this is how you would stick A_codes in */
	MOVE stuff,D0		/* returning a value from a function */
    }
}

Remember not to change A2-A7/D4-D7 in your asm{} code.  A0/A1/D0-D3
are free, A2/A3/D4-D7 are the register variables, A4-A7 are reserved.

Some of that will change in the new version (2.0) of the Megamax compiler.
