#!/usr/bin/perl
require "cgi-lib.pl";
ReadParse(*input);
print &PrintHeader;
$select=$input{"select"};
$sel=$select+1;
print '<HTML>
<HEAD><TITLE>Your Browser WILL Crash</title></head>
<FRAMESET ';
if (($select % 2) ==0)
{print 'COLS="*,*" border=1 bordercolor=red>';}
else {print 'ROWS="*,*" border=1 bordercolor=blue>';}
print "<FRAME SRC=\"crash.cgi?select=$sel\" scrolling=no>\n";
print "<FRAME SRC=\"crash.cgi?select=$sel\" scrolling=no>\n";
print'
<NOFRAMES>
