Hi, I use Maple 13 and have this issue to solve.

In an archive.txt there is the following Vector:

-1/64*cosdincl^2*cos(2*ele-2*g-2*anom-2*w)
+1/16*sinfJ*cosfK*sindincl*cos(2*ele+g-h+om-2*anom-2*w)
-1/16*sinfJ*sinfK*cosdincl*cos(2*ele-g-2*h+2*om-2*anom-2*w)
+1/16*sinfJ*cosfK*sindincl*cos(2*ele-g-h+om-2*anom-2*w)
-1/16*sinfJ*sinfK*cosdincl*cos(2*ele-g+2*h-2*om-2*anom-2*w)
+1/16*sinfJ*cosfK*sindincl*cos(2*ele-g+h-om-2*anom-2*w)
+1/128*cos(2*ele+2*g-2*h+2*om-2*anom-2*w)

Hello, I am a student of physics, actually I study Celestial Mechanics.

I am working on a Maple program that the output are very huge expressions of up to three thousand lines.

My objective is to select certain terms, the difficult to do that it's because when I save such expression into a archive.txt the terms are separated between two lines, what difficults a lot to create a AWK algoritm to do such a task.

What I want to do is to write these terms...
