Accessing indexed/hashed data through an index is even quicker than through the key in itself.
It takes 20 lines of code to implement it.
It requires creating a function $hadd() returning the Id
a property .nid for $hget
and a new function for retrieving through Id instead of through key
All the info is already collected and dealt with by mirc and you do not need more for basic database add-ons
Otherwise, hash tables are of very little use and can be laid aside by the mirc-to-mysql add-on
My position is : create something useful or do not create anything at all
And, please, read the thread before answering and many of your questions will get their answers while you are at it, besides of avoiding you make suggestions ... let's be soft saying "out of context or already discarded"
