dump
dump - create an immediate core dump
dump LABEL
This causes an immediate core dump. Primarily this is so that you can
use the undump program to turn your core dump into an executable binary
after having initialized all your variables at the beginning of the
program. When the new binary is executed it will begin by executing a
goto LABEL
(with all the restrictions that
goto
suffers). Think of
it as a goto with an intervening core dump and reincarnation. If LABEL
is omitted, restarts the program from the top. WARNING: any files
opened at the time of the dump will NOT be open any more when the
program is reincarnated, with possible resulting confusion on the part
of Perl. See also
-u
option in
the perlrun manpage
.
Example:
<![CDATA[
#!/usr/bin/perl
require 'getopt.pl';
require 'stat.pl';
%days = (
'Sun' => 1,
'Mon' => 2,
'Tue' => 3,
'Wed' => 4,
'Thu' => 5,
'Fri' => 6,
'Sat' => 7,
);
dump QUICKSTART if $ARGV[0] eq '-d';
QUICKSTART:
Getopt('f');
