Hi all,
$ref is a reference to a hash. Hash contains a component called "a"
which is an array. I would like to iterate all elements of said array.
I would like to do something along the lines of:
foreach my $elem @%$ref{a}
{
print "$elem\n";
}
Which, I think it clear, does not work. I also tried:
foreach my $elem @(%$ref){a}
{
print "$elem\n";
}
which complains about:
Bareword "a" not allowed while "strict subs" in use
and:
foreach my $elem @(%$ref){'a'}
{
print "$elem\n";
}
which complains about:
Global symbol "$elem" requires explicit package name at line 3 (i.e. -
inside the for).
Any help would be appreciated.
Thanks,
Shachar
