Hello,

	I am doing some computations which I want to be written to a file.  The
usual (>> or >>) is not sufficient as Mathematica waits for the entire
computation to be over before writing to the file. Is there any way I
can  make Mathematica write to a file dynamically?

The computation I attempted was the following:

<<combinatorica.m

e={{-1, -1, 0, 0, 2}, {-1, -1, 0, 2, 0}, {-1, -1, 2, 0, 0}, {-1, 0, -1,
0, 2}, 
  {-1, 0, -1, 2, 0}, {-1, 0, 0, -1, 2}, {-1, 0, 0, 2, -1}, {-1, 0, 2,
-1, 0}, 
  {-1, 0, 2, 0, -1}, {-1, 2, -1, 0, 0}, {-1, 2, 0, -1, 0}, {-1, 2, 0, 0,
-1}, 
  {0, -1, -1, 0, 2}, {0, -1, -1, 2, 0}, {0, -1, 0, -1, 2}, {0, -1, 0, 2,
-1}, 
  {0, -1, 2, -1, 0}, {0, -1, 2, 0, -1}, {0, 0, -1, -1, 2}, {0, 0, -1, 2,
-1}, 
  {0, 0, 2, -1, -1}, {0, 2, -1, -1, 0}, {0, 2, -1, 0, -1}, {0, 2, 0, -1,
-1}, 
  {2, -1, -1, 0, 0}, {2, -1, 0, -1, 0}, {2, -1, 0, 0, -1}, {2, 0, -1,
-1, 0}, 
  {2, 0, -1, 0, -1}, {2, 0, 0, -1, -1}, {-1, -1, 0, 1, 1}, {-1, -1, 1,

  {-1, 1, 0, -1, 1}, {-1, 1, 0, 1, -1}, {-1, 1, 1, -1, 0}, {-1, 1, 1, 0,

  {1, -1, 0, -1, 1}, {1, -1, 0, 1, -1}, {1, -1, 1, -1, 0}, {1, -1, 1, 0,

  {1, 0, -1, -1, 1}, {1, 0, -1, 1, -1}, {1, 0, 1, -1, -1}, {1, 1, -1,

  {1, 1, -1, 0, -1}, {1, 1, 0, -1, -1}, {-1, 0, 0, 0, 1}, {-1, 0, 0, 1,

  {1, -1, 0, 0, 0}, {1, 0, -1, 0, 0}, {1, 0, 0, -1, 0}, {1, 0, 0, 0,
-1}}; KSubsets[e,4] >> result.out

	I am running Mathematica 3.0 for Digital Alpha workstation
(Alpha@433MHz,  with 128MB RAM and oodles of hard disk space. But
Mathematica exits on the  above saying "Out of Memory".
