<grin> Yes, I'm good at doing that! Now if you'll just sit on this swivel chair and close your eyes, we'll proceed to the next stage..... :-) > Until now, when I had > to define a subhandler to give a special behaviour to the > column of a table, I used to define global variables that > contain the values assigned to the MIB columns That's fair enough. The agent isn't a magic box (however much it may feel like one at times), and *something* has to keep track of the various values. Whether this is a series of parallel arrays (as in your code), or a list of per-row data structures, or whatever - there has to be something that holds the values for each row, and each column. But remember that we've been talking about the 'dataset' helper. The distinguishing feature of this particular is that it's the *agent* (or strictly, the dataset helper) that looks after holding all the table data. The MIB coder doesn't need to deal with this at all. With some of the other helpers (e.g table_data/table_container), the user will define a suitable data structure to hold one row of the table, and the helper looks after holding the table as a collection of such rows. But the user still has to deal with the whole of a row. The dataset helper takes this a stage further, and looks after each row as a collection of columns. It's like having an assistant that sorts through your mail first thing in the morning, throwing away all the junk and sifting out the ones that are actually relevant. The table_data (and table_container) helpers will give you each such letter to answer. The table_dataset helper will draft the response as well - all you have to do is sign it. Neither approach is more *right* than the other - it all depends on how much you can delegate to your assistant (/helper).
