[GAP Forum] Changing line when printing to a text file

[William DeMeo]

Dear Herbert,

You might try

    outfile:= OutputTextFile(filename, false) ;
    SetPrintFormattingStatus(outfile, false);

Then a line like yours,

    Print(outfile, " ", out[i][2], "\n");

might do what you expect. It seems to work for me.

You could also read Section 10.4-8 of the manual.  I believe the
following link will take you directly there::

Hope that helps.  Good luck!

Sincerely,

William
