Well I don't want to invent something either...but what to do? So for example (10)123 would mean decimal 123? I don't know how we would parse brackets separately from expressions though. > > If we're going to add some global way to always say a number is decimal, > and I'm not sure I think that's a good idea even (I kind of think it > might be better on a case by case basis to maybe tweak some prints so > that for example "ls mmc 0:10" tells the user it's accessing partition > 16 would lead to a quick "oh that's hex, #$%@!"), I think it should > follow the radix notation, or if not, some other well known example. Can you give examples for what you are thinking for radix notation? BTW, quite a bit of the series is a clean-up, so can be reviewed separately. Regards, Simon
