Re^2: Dereferencing Mystery

Flat file isn't correct! The file is actually a listing of mostly hashes with default values to be used by a menu. The user of the menu makes some changes in the selections and it's these changes I want to save to disk for another process to read.

%Program fetch for example

%Program_fetch = ( "/airreba/procs"       => "Y",
                   "/reba/bin"            => "Y",
                   "/reba/onetime"        => "Y",
                   "/reba/perlib"         => "Y",
                   "/reba/shlib"          => "Y",
                   "/xcape/bin"           => "Y",
                   "/xcape/bin_util"      => "Y",
                   "/airreba/tables"      => "Y", );

general comment: If the only choices are on & off ("Y" & something else), use "boolean" values instead -- it will make things a lot easier and cleaner cause you'll avoid code like `if($foo eq 'Y')` (or worry about case).. use 1 (or another non-zero number) for true and 0/undef for false. Then you can just do `if($foo)`. (Depending on the usage you could just do `if(exists $someHash{someKey})` as well ..). A good reference is True or False?
