Hello,
The following uppercase'S the whole string, when all I want is the first letter.
&uppercase($bears->{"rec$n"}{name}), uc($bears->{"rec$n"}{type}) # works but caps the
whole string
}
u\$bears->{"rec$n"}{type} # does not work...
sub uppercase{
($s) = @_;
\u$s = scalar $s; ## does not work
return $s;
}
another version:
sub uppercase{
($s) = @_;
return uc($s); # works but caps the whole string
}
lastly, in this hash of hashs..
$bears = {
rec1 => {
type => 'sweater',
name => 'sweaterie',
color => 'golden brown',
food => 'mixed beries',
},
one of many... more recs heres
}
is $ (scalar) $bears, correct? should not be %bears
How would I get the lenght of $bears if I wanted to a:
for (0 .. # true lenght of $bears )
and as it is, I can not do the following, that you would use will normal hashs
foreach my $key (sort keys %bears ) {
Thanks & good day,
Dave G.
