How can I call a sub in a dedicated file?

[Davy]

Hi all,

If I want to call a sub function in a dedicated file like "my_sub.pl",
how to do that?

Or if I have a lot of Perl file contain sub function, shall I use
something like package?

Please give me some reference, thanks!

Best regards,
Davy

You load the file, then call the sub. See "perldoc -f use" and
"perldoc -f require".

Or if I have a lot of Perl file contain sub function, shall I use
something like package?

Yes, probably. See "perldoc perlmod" for how to organize your Perl
subs.

No where near enough information given. Please post a
short-but-complete script (or scripts) which demonstrate what you want
to do. If the file contains subroutine definitions, you can simply
require 'my_sub.pl';
and then call the subroutine like you would any other subroutine. If
the code is contained in a package, you either have to export the
subroutine from the package file and import it in the main file, or you
have to fully qualify it (that is, precede the subroutine name with the
name of the package and two colons).

Please give me some reference, thanks!

perldoc perlmod
perldoc perlmodlib

That was rather obnoxious and pointless, Anno. The OP very correclty
cross-posted instead of multi-posted, and you completely circumvented
the benefits of that decision - I was reading perl.beginners at the
time, and therefore did not see that you had answered the OP's question
in clpm. Had I, I would not have wasted my time by answering an
already answered question....

Huh? I trimmed perl.beginners because my news server doesn't carry it
and complained. There was no critique expressed and none implied.

Maybe his newsclient just refused to post to an unknown group. I have
even heard of newsservers that allow themselves to change the Newsgroups
header field.

My apologies. I misunderstood the reasoning. Mis-guessed, to be more
accurate, since there was no indication either way.

Sorry,
