For the following the syntax is correct but when I try to open it

When I load this in the browser I just get a blank page. The source

David's explaining it pretty well, but let me take

One solution, when not using $value = param('value');
sub parse_form {
read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
if (length($buffer) < 5) {
$head = $ENV{QUERY_STRING};
}

Anyone know of a program that can create barcodes on the screen from entered numbers?
thanks!
Puh thats tought! So i have to go the hard way for it? What a pity!
Lets see if i understand the code... Is there any source where I can read about
passing parameters to a perl script via the browser?

Well, I'd start by printing an actual content type instead of depending on CGI.pm
for that:

I just think there are too many who close their minds to anything but CGI.pm,

more efficient customized solutions.

Hmm, a perl syntax checks out, but the script seemingly dies when ran? One
thing I've found and don't yet fully understand, is it seems like when
importing other modules the perl check doesn't seem to catch undeclared subs
despite use strict- any ideas?
Either way, I digress- basic things but

I tend to always use CGI.pm to get the parameters, but
I may or may not use it to output HTML. If it's simple
HTML, I will, because it's easier and safer, but if
it's complicated, like a lot of JavaScript in the
header, or for most form input controls, I just use
print statements, either normal on

That's interesting.
You know, I work with about 5 other perl programmers, most of which do use CGI.pm,

use this:
you could use system commands if you are on winnt or w2k.
I normally just use
@filelist = `dir *.ext /b`;
foreach (@filelist){
@filename=split on the .
if last element of @filename is what you're looking for{
`rename $_ @filename[0].newext`
}
}
Please let us know a little bit more about your setup. i.e. have you
already installed mysql or are you running it on a remote server, what
OS are you running?
to connect to the mysql server from perl you will have to use the DBI
module, and the DBD:mysql module.
