Hi,

I have a problem with the order of subroutines
and I couldn't find help about that in books or
online.

Could someone tell me why this code works fine:

------------------
 #!/usr/bin/perl

 Function1();

 sub Function1() {
   Function2( 'arg' );
 }

 sub Function2() {
   my ( $arg ) = @_;
 }

------------------

and not this one:

------------------
 #!/usr/bin/perl

 Function1();

 sub Function2() {
   my ( $arg ) = @_;
 }

 sub Function1() {
   Function2( 'arg' );
 }

------------------

which yields the following error message:

Too many arguments for main::Function2 at
D:\Developpement\Perl\test.pl line 10, near "'arg' )"
Execution of D:\Developpement\Perl\test.pl
aborted due to compilation errors.

I have this problem in the framework of a rather
long (tk) script (about 2'000 lines so far), and the
calls to various subroutines are getting too intricate
for me to find an order that works (besides, it is not
a satisfying solution).

I hope this does not duplicate a previous post.
