I think maybe people (including me) really don't understand what you want.

I don't know what "need to join points" means. Just plot a line?

Anyhoo, when I do what you did I get:

IDL> PLOT, A(*), B(*)
PLOT, A(*), B(*)
^
% Syntax error.

Is this the problem you are having? If so, try

IDL> PLOT, A, B
IDL> OPLOT, A, C

or, for FG,

IDL> p = PLOT(A,B)
IDL> p2 = PLOT(A,C,/overplot)

cheers,
