One of the nice things about them is that they are strongly typed, even though accessed using a generic accessor. so for
var x: tuple of (String, Integer);
the compiler knows that x[0] is a String, and x[1] is an integer (and that x[2] doesn’t exist and is invalid)
A single tuple is not as valuable as an array of them, in my case, initialized as global constants. Would the following be the correct way to do it?
const
MyNos : array[0…2] of tuple of (integer, string) =
[(0, ‘Zero’),
(1, ‘One’),
(2, ‘Two’)];
And then how to access individual elements:
MyNos[0, 1] = the string ‘Zero’ or
MyNos[0][1] = the string ‘Zero’?
I assume MyNos[1] is the tuple (1, ‘One’)?
I find them useful for method results.
Looks correct, yes.
Yes, this one. you cannot combine array and tuple access into a single indexer access expression, as this is not a multi-dim array.
