[Gambas-user] Explictly sized array parameters in method signatures?
Hmm, I've never tried this before. Suppose a function GetCurrent(DateRange as Date[]), now intuitively DateRange is an array of 2 dates. No-one would be silly enough to pass an array with more than two elements would they? My cynical nature says yes they could/would. I could ignore the array length and just use DateRange[0] and DateRange[1] as the limits but that may produce confusing outcomes, or an error if DateRange contains only one element. I would like to define the function as GetCurrent(DateRange as Date[2]) but this is apparently a syntax error. Obviously, in this trivialised example, I could check the bounds of the passed array in the function body, I just expected that the runtime would check an explicitly sized array parameter. The real function is (of course) much more complex. The function requires an array of Dates[3][2] and another 5 parameters, some of which are optional. Any thoughts?

This may be over-simplified, but couldn't you define a DateRange structure? Or would that not provide the constraints you need? Lee __ Artificial Intelligence is no match for natural stupidity.

It's actually a struct of structs (3x2) Good thinking 99, I'll give that a go. B -- B Bruen adamn...@gnail.com (sort of) -- Dive into the World of Parallel Programming.
