Pointer to array of two floats. Just use the arithmetic combination rules
as if "," was an operator. Since you're now passing an array to a function
he whole thing would be converted to a pointer. In this case it might be more
appropriate to make them doubles... so you cast (I didn't see the original
message, but I'm assuming you're using:

typedef struct { double real, imag; } COMPLEX;

or something morally equivalent).

I implemented this in small-C for the 8080. Was a snap. I also implemented
a bunch of other BCPLoid stuff.

For example, you could do:


	A = {
		int i;
		for(i = 0; i < ac; i++)
			if(av[i]=="all")
				break;
		return i;
	};

Well, the rest will have to wait. My baby has just done something
unspeakable and I have to go clean it up.
