[Coco] Does DEF FNX for Basic only take one parameter?

[John Guin]

Hello all,

I was working on a basic program to do something like:
DEF FNX(A,B)= some function of A and B

Basic gives a syntax error for this, but my Coco3 book says I can pass a
parameter list to it.

I'm assuming the book is wrong, and DEF FNx can only take one paramater, but
does anyone know if that's right?

Thanks,
John
