: Note...with this you get also get to return values via simple assignments.

Alternative syntax is to present these as out parameters. Here are two ideas:

Eg[1]:
void f (z) out (a,b) 
	float a;
	int b;
	int z;
{
	a = 3.14159;
	b = 0x5050;
}
main()
{
	int i,j;
	f(4) out (i,j);
}


Eg[2]:
void f (z, out a, out b) 
	float a;
	int b;
	int z;
{
	a = 3.14159;
	b = 0x5050;
}
main()
{
	int i,j;
	f(4, i, j);
}
