Hi all,

I'm relatively new at coding in Perl, but I've learned enough to get around. I recently discovered how awesome the CPAN really is, and I'm starting to switch my programs over to use Getopt::Long to capture command-line arguments that users may use on my programs.

One program I have written does data analysis and writes the results to a default location. I implemented a way to allow users to change the location to write to, but how I did this is not compatible with the Getopt::Long module, and quite frankly is extremely inelegant.

What I'd like to be able to do is the following (pseudo-code): 

if($user_wants_to_save && ! $location_specified){
    $save_location = ask_user_for_save_location();
}else{
    $save_location = $location_specified;
}

What I have thus implemented is: 

GetOptions(
    's|save_to:s' => \$user_wants{CUSTOM_SAVE_PLACE},
);

[download]

So if the user uses the -s or --save_to flag, it will use the next argument as the save location. But say the user *doesn't* specify the save location in the command line. How would I go about asking_user_for_location()?

Thanks all.
