if($tmp eq 'F'){

}elsif($tmp =~ /[MICL]/){
... # do something ...
}else{
... # do something
}
}
If you have a few different cases, an if/elsif/else chunk like this one is fine, but if you have a lot of possibilities, you should consider building a dispatch table: fill a hash with subrefs and do something like (untested)
$tmp = $some_result;
my $handler = $handlers{$tmp};
&$handler(...) if $handler; # might be undef, as in 'F' case
This has the disadvantage of failing silently if you get an unexpected value in $tmp; you could fix it by giving 'F' a do-nothing subroutine and raising an error if $handler is undefined.
