Re: Iterating through a HoHoH ... does a particular sub-hash exist?

Are you using the strictures, jedikaiti?

If you did, you would have seen that

$cmdData->{$cmd}{subfields}
[download]

gives you an error, unless you have elsewhere declared $cmdData.

$cmdData->... contains a scalar reference and has nothing to do with your hash %cmdData. You probably meant something like $cmdData{'command_2'}->{subfields}.

Update: Forget what I wrote above. I somehow totally missed the code in your node. Thanks almut for pointing that out to me.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

I guess the retrieve in `my $cmdData = retrieve('file.pm')` would return a reference to the hash in question, so things should be fine.	[reply] [d/l]
