In that link I gave the answer. I was using ImportMatrix. Just change that to ImportVector.

I wrote:
restart;
A:=ImportMatrix("G:/MapleDiverse/MaplePrimes/archive.txt");
add(A[i,1],i=1..numelems(A));

Hi,first, thnx for your attention in all of my posts. I tried to reach my objetive by your way but I wasn't succeeded.At that post I was trying to create a file with "one term by line", I got sucess converting my expression to a vector than later using ExportVector to save to a .txt archive. Then I could ran my awk algorithm and everthing went ok. Now I have to transform this into an expression. I first have to "ImportVector" than convert to an expression again. Just don't know how to perform that.

I didn't forget your examples, unfortunately I couldn't get the things right yet.

I got now:

[> Error, unable to execute add

Your hints are helping me a lot, now I converted my vector into a list and did:

add(i, i = Z),  this command sums every term of my list. Sucess. Thnx a lot =]
