How about putting your variables in a matrix and using load and save
with Octave's ASCII format?

  v1 = rand (5, 1);
  v2 = rand (5, 1);
  tmp = [v1, v2];
  save -ascii file tmp

should produce a file with contents that look something like this:

  # Created by Octave 2.1.33, Mon Jan 29 08:42:35 2001 CST <address@hidden>
  # name: tmp
  # type: matrix
  # rows: 5
  # columns: 2

Octave's load command should have no trouble reading that file.
