Re: Multiple if-else statements using C-style ternary operator

my $message = $status == 2 ? 'HIGH' 
            : $status == 1 ? 'MODERATE'
            : 'LOW'

print $message

Depending on the depth of status, you may want to use a hash

my %status_message = { 2 => 'HIGH', 1=>'MODERATE', 0=>'LOW' };
my $message = $status_message{ $status } || 'LOW';

Or even a standard array if the values really are ints in a 0..n range.

my @status_messages = qw( LOW MODERAGE HIGH );
my $message = $status_messages[$status] || 'LOW';

These are both made a little more odd by the the inclusiveness of the default "LOW" value. Your demo code makes message "LOW" for any status other than 1 or 2.

`my %status_message = { 2 => 'HIGH', 1=>'MODERATE', 0=>'LOW' };` That's not what you want. That creates a hash with a key of the form `"HASH(0xDEADBEEF)"`, and an undefined value has the value. Perhaps you intended to write paren instead?	[reply] [d/l] [select]
