Stein Vidar's response spawned a thought. Why aren't you using SPAWN?
One point of any programming language is to proceduralize mundane
tasks so you don't have to keep doing the tasks yourself.

You could start with something like this:

pro dofortran, array
;; Call fortran program
spawn, 'runfortran', output

;; Determine number of elements in array - assume it's a 3xN array
n = n_elements(output)
array = fltarr(3,n)

for i = 0L, n-1 do begin
v0 = [0., 0., 0.]
reads, output(i), v0
array(*,i) = v0
endfor

return
end

Obviously you will have to customize for your program name and the
number of variables, etc.
