Hello.

So I am currently on a project to document someone else's code (ugh!), and from what I can tell, the programmer in question doesn't seem to be all that familiar with perl. I am seeing some things that definately run counter to things I was taught or have learned. So I figure I'd consult the Monks for clarification.

Here's the first oddment:

# at the top of the script:
  $sb="\013";
  $eb="\034";
# those two values are never altered anywhere else in the main portion
+ of the script.


# then, later...

sub whatever {
    local ($sb);
    local ($eb);
    $sb="\013";
    $eb="\034";

# rest of sub

}

Is this redundant? Wouldn't my() be better suited to do this? I'm not sure why he even wants local copies of those vars, since they never change. I guess what I'm looking for is a practical explanation of the difference between my and local, and the situations in which you would prefer one over the other. I have strict in use all the time, but I have only ever used my(), so I'm not clear on the difference.
