Are you talking about creating a flow chart? If so, I currently use Visio and would recommend it. If you're talking about some tool to automatically create a flow chart of existing Perl code, I don't know of any. When I need to create a flow chart of a complex section of code that has if statements, and loops, and jumps all over the place, I just go through it line by line.

my $pid = fork();, , The parent's $pid will contain the process ID of the child, the child's $pid will contain 0, if the system is out of resources and cannot fork another process it will be undefined., , Logically check the value to have each process run through different code., , if ($pid == 0), {, # the child does something, }, else, {, # the parent does something, }

easy one about forms.....
Ive followed the instructions at namehog.net:, http://www.namehog.net/support/formemail.htm , to put a form on my webpage. But it doesnt work. I get this error message....could anyone help??, , CGIWrap encountered an error while attempting to execute this script: , , Error Message: No such file or directory , Error Number: 2 , This message usually indicates there is a problem with the script itself. Often this indicates either that the #! line of the script is incorrect, or the script was uploaded in binary mode instead of ascii mode. Check to make sure that the script does not have control-M's at the end of every line. That will prevent it from executing. An easy fix that takes care of this most of the time is to put '#!/.../perl --' instead of '#!/.../perl' on the first line of the script. , If you are not the owner of this script, please forward this error and the URL that caused it to the script owner. That is often the component in the URL right after /cgiwrap/.

1. Perl Constants (use constant)

In PHP, you declare constants using the define keyword:

define("CONST_NAME", "Value");

Constants in PHP are case sensitive. A common standard in PHP is to use all-uppercase letters, with underscores to separate words within the name.
