the "This Quote" in the
hidden field, there is now the problem of decode_entities perchance
more than once???
original input: "This Quote"
saved as hidden: $quot;This Quote$quot;
so the
$hiddenValue = param('hiddenValue');
would return it as
cally obliged
to maintain code that was not started this way I stole this
trick from some CGI stuff from '99 () and just thought it made much
better sense.
Not sure I agree with you about building tables by hand But
I am sure your experience offers you the case work to recommend
er approach is to use a C-style for-loop.
Is there any given advantage of one over the other in
terms of performance and/or maintainability?
the two stalking horses of my life.
and these over
print "index -> " . $counter++ . " element -> $_\n" for (@array);

moment that you decided that all of the 'messages' have
to be 'preserved' that things get messy
using the 'm?' side annotation I put up, message m1 would need to
get out of the data stream
m1: lA , m2, LG
and we then have to parse out of m2 it's info
rldoc ipc

can find the 'Source code' download
Happy Hunting!

ed before they are used in the main loop
and hopefully they do not need get interwoven too badly. This way
when You notice that only the main changes - it's clearly obvious
that you should just Whip Out the h2xs - make a module of it all -
and shorten up your 'scripts'

s not clear
to me that the perlcc is not generating "foo.c" files as intermediary
steps enroute to the actual compile.
you might try the '-v' flag
perlcc -v -o hello hello.pl
to see if this would work As the doc says, this should
be treated as 'highly
o edit your crontab file and
put in your iterator like above.
0 3 * * * MyCoolScript
and it will run at 3am each day
So we are back to the problem -
why are you in a 'sleep' cycle in your script?
Is it a matter that it needs to be continuosly running?
