Subject: Pointer to Array

Message-ID: <1192542030.745091.64900@q5g2000prf.googlegroups.com> (raw)
I'm attempting to make a pointer to an array... or in a sense
"rename" an array.
I'm combining code from two very similar systems. Lots of code.
I have thousands of lines of code that's exactly the same, using
(for just an example) an array of Integers.
There is a store file in each system that declares:
-- system 1
type INT_ARRAY is new Integer (1..SYSTEM_1_SIZE);
Int_Array_Var : INT_ARRAY;
-- system 2
type INT_ARRAY is new Integer (1..SYSTEM_2_SIZE);
Int_Array_Var : INT_ARRAY;
---------
so in other words, the variable names are the same, types are the same
only the size of the array is different..
then I have code in both systems that use that array like:
For I in Int_Array_Var'Range loop
-- Do lots of stuff with Int_Array_Var
end loop
------
I want to keep that code untouched if possible. I'm hoping there is a
way
in Ada to do something like
type INT_ARRAY is array (Positive range <>) of Integer;
Int_Array_Var_System1 : INT_ARRAY (1..System_1_Size);
Int_Array_Var_System2 : INT_ARRAY (1..System_2_Size);
And I'd like to so something at run time that is like:
if usingSystem1 then
Int_array_Var = "pointer to Int_Array_Var_System1"
elsif usingSystem2 then
Int_array_Var = "pointer to Int_Array_Var_System2"
by changing the pointer I'm hoping to keep most of existing code the
same.
Is there any method in ada to do this?
