simply depositing in to an account. There are still 2 fns that use dosync but only modify a single identity, namely deposit! & withdraw!. I don't see how else this can be done since they are refs. I would appreciate feedback for this (hopefully) last version... many thanks in advanc

Re: preferred way to dereference a ref: outside or inside dosync?

also I forgot to add that having the bank in some reference type allows opening/closing new accounts, an operation that at least to me sounds like it needs coordination... So which way is preferred? map-ref that stores values, map that stores refs or map-ref that stores refs? Jim On 21/11

ote, is the mega-ref (the entire map in a ref) approach generally suggested ? I initially had a map-ref with agents inside (the accounts) but I find it a lot simpler to just have the map-ref...what ref-granularity are people suggesting for the bank example? Jim -- -- You received this messa
