Re: How to eliminate warning message on hash value?

Update: The original code failed to compile! But by using Marshall's suggestion, if I replace '$$db{User}' with '$db->{User}, it compiles. But I still get the warning message around 2 million calls.

Thank you

Also be aware that there is a difference between checking if a hash value is "defined" vs "exists". It has to "exist" in order to be "defined". `if ( exists $RSubtree{$curuser}{$$keyptr} ) { $datapos = $RSubtree{$curuser}{$$keyptr}; }` [download]	[reply] [d/l]

Yes, there is no difference between the two. It's purely a stylistic improvement.	[reply]
