Re: pipe one function output to another

map is the way to do it:

my @arr = map uc, split(/:/, $info);

BTW,

for(my $i=0; $i<$iLength; $i++) { $arr[$i] = uc($arr[$i]); }
[download]

isn't very Perlish. The Perl way (other than using map) would be

for (@arr) {
  $_ = uc;
}
[download]

or even

$_ = uc for @arr

`for (@arr) { $_ = uc; }` [download] That may be the "Perl way", but according to the Damian Conway-authored Perl Best Practices, a better way would be: `for my $index (@arr) { $index = uc $index; }` [download]	[reply] [d/l] [select]
