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,
paulv

NO.WHEN I SAY "JOIN THE DOTS" I WANT TO CREATE LINES VERTICAL, JOINING POINTS EQUIVALENT, WHICH ARE ANOTHER BELOW. I HAVE TO DO AFTER PLOT, A, C AND OPLOT, A, B

My guess is this is what you are asking for:
plot,a,b
oplot,a,c
for i=0,9 do oplot,[a[i],a[i]],[b[i],c[i]]
