Save Coeffs

Like the Save Coeffs in Rotate, this will write out the coefficients,
as viewed on the variable bars, into an ascii file as a two column
matrix.  The first column contains the X coefficients of all the
variables and the second contains the Y coefficients. If XGobi is
running from within S these coefficients will be written out as a
vector.

Behavior of the "Solicit File Name" window:

 The editing behavior in this window follows emacs conventions.
 These instructions may help you if you aren't familiar with emacs:
   Use the cursor to position the caret between two letters;
   as you type, characters are entered at that position.
   You can use your customary backspace character.
   Use "Control-k" to delete all characters from the caret
   to the end of the line.
