<H2>updatedisplay</H2>
<HR>
Force display update, or suspend/resume updates
<HR>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>updatedisplay</B> [<B>suspend</B>|<B>resume</B>] <BR><BR>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>updatedisplay</B> command allows the display redraw to
be suspended and resumed. The main situation where this is
useful is inside a script or series of commands, where it is
not desired to have the display refresh at each step. Areas
needing to be redrawn will accumulate and be processed all at
once when <B>updatedisplay resume</B> is called. <P>
Calls to <B>updatedisplay suspend</B> can be nested, so that
the display will not update until the same number of calls
to <B>updatedisplay resume</B> have been encountered. <P>
Without arguments, <B>updatedisplay</B> forces an immediate
display redraw.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>updatedisplay</B> is implemented as a built-in window command in <B>magic</B>.
