What do you mean by "doesn't work"? I wrote this sample code and got
the following output:
<example>
#!/usr/bin/perl -w
use strict;
my @dates = (1);
my @themes;
my @cities;
do_something(\@dates, \@themes, \@cities);
@themes = (shift @dates);
do_something(\@dates, \@themes, \@cities);
shift @themes;
do_something(\@dates, \@themes, \@cities);
sub do_something {
my @dates = @{$_[0]};
my @themes = @{$_[1]};
my @cities = @{$_[2]};
if(@dates && !@themes && !@cities) {
#do something with the data in @dates
print "do something with the data in \@dates\n";
} elsif(!@dates && @themes && !@cities) {
print "do something with the data in \@themes\n";
} else {
print "do nothing\n";
}
}
</example>
<output>
do something with the data in @dates
do something with the data in @themes
do nothing
</output>
Which is exactly what I would expect. Perhaps you could post the
original code you had problems with?
