Subject   st: simple data input question- expanding macros

Hi, I apologize for such a simple question. I hope to eventually participate in statalist on a much higher level.

I would like to input data that I have in strings manually in a .do file.
That is, say I have a for loop going through a list of a bunch of strings, how can I use those strings to input data?

Say, I have a macro called color.
and, I have an existing dataset with blue and green as observations (there is only one variable, COL).
Why doesn't the following work:

local color = "red"
input
`color'
end

I tried the above code using a global variable as well, to no avail:

global color = "red"
input
${color}
end


Is there a better way to do this? How do I expand my macro before anything else happens?

Thank you!

PS. is there any good forum online that might be better for beginner questions?
