<P>
An element of a array character variable is a character string, for example,
<CODE>T</CODE> is an array character variable with <code>3</code> elements:</P>
<font color="blue"><PRE>
T[1] = 'This is line one'
T[2] = 'This is line two'
T[3] = 'This is line three'
</PRE></font>
<P>
Array character variables can be defined with the
<CODE><a href="../Commands/Read.htm">READ</a></CODE>
command by entering more than one line number to read. For example:
<font color="blue"><PRE>
READ\TEXT FILE.DAT/[1:5] T
</PRE></font></p>
<P>
creates array character variable <CODE>T</CODE> with
<code>5</code> elements. Array character variables can also be defined with a
character assignment, as above.</p>
<p>
To specify the character elements of an array element of a array character
variable, use another set of brackets. For example, if
<CODE>T[3]='abcdefghijkl'</CODE> then
<CODE>T[3][1:10:2]</CODE> specifies characters
<code>1, 3, 5, 7, 9</code> of array element <code>3</code> of the array
character variable <CODE>T</CODE>, which is
'<CODE>acegi</CODE>'. There is no maximum number of array elements for a
character variable. There is no maximum character length for an
array element.</P>
