<h2>
<tt>#control </tt><i>attribute</i><tt> </tt><i>value</i>
<hr></h2>
<h2>DESCRIPTION</h2>
Set various operational modes.<tt> </tt>
Note: This is part of the general script processing package and
has little use in the ploticus context.<tt> </tt>
<h2>ATTRIBUTES</h2>
<i>attribute</i> may be one of:
<p>
<b>evalvars</b>
<dl>
<dt><dd><p>
<i>value</i> should be <tt>no</tt> to turn off evaluation of variables
and <tt>yes</tt> to turn it on. Default is <tt>yes</tt>.<tt> </tt>
</dl>
<p>
<b>dot_in_varnames</b>
<dl>
<dt><dd><p>
If <i>value</i> is
<tt>yes</tt>, variable names may contain periods (.).
If <i>value</i> is <tt>no</tt>, period will be used as a delimiting
character when scanning variable names in the script, and variable
names cannot contain any periods.
The default is <tt>no</tt> unless sql database functionality is included
in which case the default is <tt>yes</tt> (since sql join result field names
contain periods).<tt> </tt>
</dl>
<p>
<b>suppressdll</b>
<dl>
<dt><dd><p>
<i>value</i> should be <tt>yes</tt> to suppress data-less lines, and <tt>no</tt>
to show data-less lines. Default is <tt>no</tt>.
A data-less line is a line
having one or more variables, all of which evaluate to a zero-length value.<tt> </tt>
Suppressing data-less lines is sometimes useful, for example, when displaying
multi-line entities such as postal addresses.<tt> </tt>
