You could store your hashes within a hash:
my %hashes = (
DpInfoOperation => {
Net =>2,
Retrain =>2,
BER =>3,
},
CpuOperation => {
High=>1,
Low=>2,
};
if ($file =~/$FileName/i)
{
$tmp = $FileName.Operation;
$Operation = $hashes{$tmp};
last;
}
Now $Operation contains a reference to the appropriate hash (assuming $tmp
eq one of the keys of %hashes). So when accessing the hash you need to
dereference:
keys(%Operation) becomes keys(%$Operation)
and
$Operation{$Opp} becomes $Operation->{$Opp}
