My apologies, apparently I was successfully using this feature without 
realising its correct syntax definition. Where is it documented? help 
comma does not seem relevant.

I was thinking the following two uses were the same thing. It seems the 
first is a separator, second is an operator:

gnuplot> plot a=1,b=2, sin(x)
fn(x)=( a=1,b=2, sin(x) )
