The <CODE>RCHAR</CODE> function accepts a numeric scalar as first
argument and returns a string. It converts the numeric value to a string using
the default format <CODE>%g</CODE>. You can
specify a C style format string by including it as the optional second string argument.</p>

Strings may be appended together using the <a href="../Operators/append.htm">append operator</a>,
<CODE>//</CODE>. Scalar values can also be
appended to strings using the <CODE>RCHAR</CODE> function. For example,
suppose <CODE>A = -1.234</CODE>, and <CODE>T</CODE> is a
string variable with <CODE>T = ' units'</CODE>.</p>
