<P>
The <CODE>WRITE</CODE> command is a general purpose writing
command for vectors, scalars, matrices, or character strings. The variable type that will
be written depends on the qualifier appended to the command. The parameters that are
expected also depend on this qualifier.</p>
<p>
<font size="+1" color="green">Write vectors</font></p>
<p>
By default, the <CODE>WRITE</CODE> command writes vectors to a
file. If the <CODE>\APPEND</CODE> qualifier is used, and if the
output file already exists, the data will be appended onto the end of the file. Columns of
data will be written to the file, where the <CODE>I</CODE><sup>th</sup> column will be
vector <CODE>xI</CODE>. The number of lines that are written to the file will
be the minimum length of the vectors. A maximum of <CODE>29</CODE> vectors can be written
with one <CODE>WRITE</CODE> command.</p>
<p>
<font size="+1" color="green">Example 1</font></p>
<p>
If you have a vector, for example, <CODE>X</CODE>, and enter
<CODE><font color="blue">WRITE FILE.DAT X X X</font></CODE>
then the following values will be written to the file:</p>
<p>
<pre>
X(1) X(2) X(3)
X(4) X(5) X(6)
...
</pre></p>
<p>
<font size="+1" color="green">Example 2</font></p>
<p>
To write the vectors <CODE>X</CODE>, <CODE>Y</CODE> and <CODE>Z</CODE> to the file
<CODE>DUM.DAT</CODE> so that there will be three columns of numbers in the file, enter:
<CODE><font color="blue">WRITE DUM.DAT X Y Z</font></CODE></p>
<p>
If you enter:
<CODE><font color="blue">WRITE DUM.DAT X X Y Y Z Z</font></CODE>
then the following will be written to the file:</p>
<p>
<pre>
X(1) X(2) Y(1) Y(2) Z(1) Z(2)
X(3) X(4) Y(3) Y(4) Z(3) Z(4)
X(5) X(6) Y(5) Y(6) Z(5) Z(6)
... ... ... ... ... ...
