Pass it as a referance.
#!/usr/bin/perl -w
@sample_array = ('hi', 'there', 'steve');
$sample_array_ref = \@sample_array;
&PRINT_CONTENTS($sample_array_ref);
exit 0;
sub PRINT_CONTENTS{
my $local_ref = $_[0];
foreach (@{$local_ref}){
print "string = $_\n";
}
}
You can also clean the code up by creating the ref as an anon array if
you wanted like this.
this
------
@sample_array = ('hi', 'there', 'steve');
$sample_array_ref = \@sample_array;
Would become this
-------
$sample_array_ref = ['hi','there',steve'];

Subject: Perl question
Hello all,
I have a question about perl. I'm trying to pass an
array into a subroutine, but I don't know what the
proper way to receive it in the subroutine is. Below
is an example of what I'm trying to do. The ???
represents what I do not know what to put in.
@sample_array = ('hi', 'there', 'steve');
&PRINT_CONTENTS("@sample_array"); exit 0;
sub PRINT_CONTENTS
{
@local_array = ???
foreach $string (@local_array)
{
print "string = $string\n";
}
}
TIA for any help.
