Re^3: Problem with DBM hash of anonymous arrays

There is no "PHASH". There is a $PAHASH, which is a scalar containing a reference to an anonymous hash and there is a %PAHASH, which is a hash (tied to a dbm file), but is unrelated to $PAHASH.

If you do $PAHASH{$something} you're refering to %PAHASH. If you do $$PAHASH{$something}, you're referering to the hash referenced by $PAHASH. This can be confusing in the beginning, I know.

Take a look at perlreftut. But most of all, get in the habit of using strict. It'll save you from a lot of bugs.

The way I saw it was like this: `%PAHASH` is a named hash. `$PAHASH{key}` is referring to a scalar value stored in %PAHASH. `$$PAHASH{key}[index]` is referring to a (dereferenced) scalar value, stored in an anonymous array which is a value in %PAHASH. This is wrong, then? Sorry if this seems stupid by the way...	[reply] [d/l] [select]

Yes this is wrong :-) It parses like: `$PAHASH->{$key}->[$index] # hashref-> hash ->array` [download] While you want `$PAHASH{$key}->[$index] # hash element ->array` [download] Which can also be written as `$PAHASH{$key}[$index]` [download] update: Or maybe you want `${$PAHASH{$key}[$index]}` [download] If you really want the value as a reference to a scalar (I don't see the point of doing it) "What should it profit a man, if he should win a flame war, yet lose his cool?"

Ah, cheers. I think I have it straight in my head now :-) I can get it to work with an ordinary hash table now, just not the DBM hash! Always problems!	[reply]
