Buckaroo Buddha has asked for the wisdom of the Perl Monks concerning the following question:
i had this working at one point but it suddenly stopped (grrr)
sub BackAndForth { my ($filename) = @_; # make multi-dimensional hash here ... it looks like # $ALLDATA{$filename}{$key1}{$key2}{$key3} = [@array] return (%ALLDATA); } my %ExternalHash = &BackAndForth('filename.csv'); %ExternalHash = &BackAndForth('filename2.csv');
now i played around with it a bit and can't remember what i may have changed ... $ here, % there (yadda yadda) if i do a variable dump on %ALLDATA i get ...
%ALLDATA = ( 'key1' => HASH(0x9021f6c) 'key2' => HASH(0x90154a8) 'key3' => ARRAY(0x9015400) 0 value1 1 value2
but if i do the same on %external i get
%thisDataset = ( '' => HASH(0x876f324) 'key2' => HASH(0x9029220) empty hash)
looking at the memory locations, we can see that they're not the same hashes (but that should be obvious cause i'm getting the return of a strange set of data) where is the garbage coming from ? prehaps
return(\%ALLDATA) %external = (yadda yadda) or $external = (blah ...
