What is "ob"? Object, perhaps? Just a guess, but if you are interested in the obarray in general I remember asking about it way back - because as I recall, the documentation was cryptic to say the least - and there were some very advanced replies, as I remember. So hit the archives, look for Emanuel Berg and "obarray" in the Subject header. Report back everything you learn :) As I recall, the obarray is a data structure (some kind of hash table) to store stuff dynamically (i.e., not just in memory) so that you can filter and do stuff with it - for example, to provide the set of operands possible after you invoke a command. -- underground experts united: http://user.it.uu.se/~embe8573
