Hi
I'm trying to understand subroutines.
#!/usr/bin/perl
&marine()
sub marine {
$n += 1; #Global variable $n
print "Hello, sailor number $n!\n";
}
This doesn't work. Is &marine() incorrect? How would I call the sub marine?
Thanks
Amichai
Oh that curly! Ignore my previous message. Thank you.

Hi,
be nice to yourself and allways "use strict;"
and don't call subs with &, unless you know why you need &.
hopefully you can avoid some problems when you're writing perl code.
#!/usr/bin/perl
use strict;
marine();
HTH,

i am trying to figure out how to use the subroutine in a library now.
so I did this.
I name one script sub.pl and the library sub-lib-pl:
the script.pl contains:
#!/usr/bin/perl
use strict;
require 'sub-lib.pl';
marine();
The sub-lib.pl contains:
#!/usr/bin/perl
sub marine {
$n += 1;

to add 1 at the end of sub-lib.pl,it would work.
echo 1 >> sub-lib.pl

Yeah that works now. Great. Finally I'm getting this...after months. Thank

That's rubbish,
You can call a sub before you create it as you say. At compile time the
entire code is done (bar some exceptions)
The issue here is drop the & unless you really know what it does
my($n);
marine();
sub marine {
$n += 1;
print "Hello, sailor number $n!\n";
}
Works fine.

thats because you're not using perls prototyping feature at all.

Dear Folks,
I need to print diagnostic message strings like:
warn "$parent/$child does not exist: verification failed\n";
in conditional blocks that are nested and indented. This means that, on
occasion, the message string overflows to the next line in an 80-character line
in my source file.
Is there a way to dump the HTML code for a web page? I need to write
a script which will collect and summarize content from intranet web
pages. By dump, I mean to read it the same way you would read a file
and parse its contents. Thanks.
