<h1 class="topictitle1">Arithmetic expressions</h1>
<div><p>The operands in an arithmetic expression must be decimal constants
or decimal or integer CL variables. </p>
<div class="section"><p>An arithmetic operator (only in symbolic form) must be between
the operands. The results of all arithmetic expressions are decimal values,
which may be stored in a CL variable.</p>
<div class="note"><span class="notetitle">Note:</span> The division operator (/) must
be preceded by a blank if the operand that precedes it is a variable name.
(For example, <samp class="codeph">&amp;A /2</samp>, <em>not</em> <samp class="codeph">&amp;A/2</samp>.)
All other arithmetic operators may optionally be preceded or followed by a
blank.</div>
<p>Arithmetic operands can be signed or unsigned;
that is, each operand (whether it is a numeric constant or a decimal or integer
CL variable) can be immediately preceded by a plus (+) or minus (-) sign,
but a sign is not required. When used as a sign, no blanks can occur between
the + or - and its value. For example, a decimal constant of 23.7 can be expressed
as +23.7 or -23.7 (signed) or as 23.7 (unsigned).</p>
<p>The following are
examples of arithmetic expressions:</p>
<pre>(&amp;A + 1) (&amp;A + &amp;B -15)
(&amp;A - &amp;F) (&amp;A+&amp;B-15)
(&amp;A + (-&amp;B))</pre>
<p>If the last non-blank character on a line
is a + or -, it is treated as a continuation character and not as an arithmetic
operator.</p>
