I'm still having trouble with this. I've tried using functions, as suggested, but it doesn't allow overloaded functions in the varient part. Here's what I tried:
"
type
small_lorry_load is new integer range 1..2;
type
medium_lorry_load is new integer range 1..18;
type
large_lorry_load is new integer range 1..36;
type
all_lorry_loads is new integer range 1..36;
type
lorry_size is (small,medium,large);
type
lorry_number_plate is new string(1..8);
function load(x : lorry_size := small) return small_lorry_load;
function load(x : lorry_size := medium) return medium_lorry_load;
function load(x : lorry_size := large) return large_lorry_load;
type
lorry_type(lorry : lorry_size) is
record
number_plate : lorry_number_plate;
location : depot_name_type;
destination : depot_name_type;
case lorry is
when small => lorry_load : load(lorry);
when medium => lorry_load : load(lorry);
when large => lorry_load : load(lorry);
end case;
end record;
"
I know that the syntax is wrong - I've been trying all sorts of alternatives. What have I not understood?
