IMO your subroutine seems to be fine
however, you may have problems in the place where you are calling this subroutine
at all these tough times, perl -d is your helper; use it; see
perldebug
BTW your post title, 'simple hash question' seems to be irrelevant to the post!.
UPDATE
good that you know you can use hashes, why you have not tried it?.
see here about hashes
for your case you can use some thing like below
my %flag;
..
$flag{'user'} = $user;
..
$flag{'uid'} = $uid;
...
...
return %flag;
at the calling place use
my %userflags = buildCommand(..)
then access the values like $userflags{'user'}
or use references
return \%flag;
at the calling place use
my $userflags = buildCommand(..)
then access the values like $userflags->{'user'}
see
perlref for more details on references.
learning perl is a good place to start.
