I am not suggesting that you use backquotes. They are for something else.
I am just trying to explain why it does not work to use @FILE or @ARG1
inside ordinary quotes.
Try splitting this into two stages.  First construct the string to be
executed.

   commandstring = "< paste" . ARG1 . "| awk '!/^\#/ { print $2 }' "

Confirm that this did what you wanted

   print commandstring

Then use it in a plot command.

   plot commandstring
