By the way, a better alternative to the most important line from the programs I sent you can be written more clearly:
$hash{$current_function}->();
respectively:
$current_function->();
... if you don't like too many braces. :-)

Hi, The first thing I want to know is this. Is there a way to make a self-executable Perl program that I can just give to someone and they can run it without needing to install the Perl interpreter? The second thing is this. Can I do this. Can I have a hash whose keys are a set of values and whose values are the functions in my program I want to perform. For example, I don't want to say if key is this, perform this function, elseif key is this, perform that function. I simply want to look up a key and perform whatever function is in the value for that entry in the hash. Can I do this? If so, how? Thanks.
