<h2>12. Style Variables
<a name="12. Style Variables"></a>
</h2>

There are
a number of global style variables in pic that can be
used to change its overall behavior. We&rsquo;ve mentioned
several of them in previous sections. They&rsquo;re all
described here. For each variable, the default is
given.

Any of these variables can be set
with a simple assignment statement. For example:

Figure
12-1: boxht=1; boxwid=0.3; movewid=0.2; box; move; box;
move; box; move; box;

In GNU
pic, setting the scale variable re-scales all
size-related state variables so that their values remain
equivalent in the new units.

The
command reset resets all style variables to their
defaults. You can give it a list of variable names as
arguments (optionally separated by commas), in which case it
resets only those.

State
variables retain their values across pictures until
reset.
