Eu doesn't have this ability, but there are some work arounds you can use.
(You might ask Kat--she seems to do this in mIrc.)

What I would do in this case, is use a sequence:
-- Begin Pseudocode
sequence Price = {}
for i = 1 to 10 do
Price &= val(CLOSE) -- or however you'd get the value in Eu
end for
-- End Pseudocode
Then, you could access it like:
for i= 1 to 10 do
? Price[i]
end for
It seems (from your example), that this would accomplish everything you'd
need for it to do, and might even make life simpler down the road (you don't
have to rebuild the var name when you want to use it). Sequences seem to be
one of Eu's greatest assets IMHO, but it takes a bit of practice to figure
how to use them effectively, especially when you've come from another
language.
