@treeform, that's the way it's usually done, but the idea is to prevent
redundant naming for those entities that represent the same. If either the
labels or the field names can be duplicated, then the code from then forward is
cleaner and less cryptic.
Here how it works in Pascal, for the 1D, 2D and 3D part. It doesn't look as
nice, but the principle is the same: field x will be shared by 1D, 2D and 3D
points; field y for 2D and 3D; and field z will only be used by 3D.
Type
Point = Record
X : Longint;
Case byte of
2 : (Y : Longint;
case byte of
3 : (Z : Longint);
);
end;
Run
That's the way is not done that way because
