Hello everybody,
I have a perl code that generates a sequence of values which i want to plot
on y-axis against 1,2,3... on x-axis. I've read that GD::Graph could be used
for it. But I've never done modular programming. Also, I don't know how to
install modules from CPAN.
Are there any other easier

Here's a solution that works for the cases you've provided:

I'd like to evaluate user input only where it makes sense, e.g.

I've tried:

In the context of subroutines, it copies the first scalar argument
passed to the routine to the variable $msg. If more than one argument
was passed, the others aren't touched by this statement -- as yo

If I understood you question properly you want to know why people use
shift in subrutines and how does shift work.
I will try to make it short:
shift works on lists, it removes the first element of the list ( the 0
indexed element ) and returns it as a lvalue ( if there are no more
elements in a l

Hi Perlers,
I have one nice question for you, I was run into common problem:
need to repeat certain number of times something, until is succesful.
For example - download webpage, FTP upload, connect to some host and
so on.
I ask you for some general (or it can't be possible - FTP upload)
function,
Perlers,
I'm struggling; I'm using WMI to monitor a few processes (kinda like my
last disk monitor) but my output repeats the first process in a list for
as many items as I have in the list. See below:
use warnings;
use strict;
use Win32::OLE('in');
my $megaBytes = "1048576";
my $serverObj =
QUESTION: What is the purpose of the line "my $msg = shift;"? I am
guessing it is for the @_ array but what list element is there to be
shifted off? It seems that the shift function is in a lot of
subroutines and I am confused as to their purpose.
#!/bin/perl -w
(my $PROGNAME = $0) =~ s/^.*\///;
Yes! That works. Thank you so much for your time.

I would like to display the daily calendar information from a perl script:
http://webapps.sbuniv.edu/daycal/ within an html page so it looks like this:
http://www.sbuniv.edu/. Right now I have to manually enter the calendar
information. I would like for it to be dynamic. Make sense?

Hello ,
in your examples you're opening "files" not dir's , to open a directory use
this instead
opendir(DIR,$dirname) or die $!;
my @content = readdir(DIR);
closedir(DIR);
then to read files inside it ,
for (@content){
print ;
}
that's it , if you need to remove ("." and "..") which means the
