Initialization of variables

[riwu]

By default, variables in Pascal are not initialized after their declaration.

Is there a compiler option or some tools that change this behavior and automatically initialize integers to 0 etc?

Also, why does Pascal not allow initialization of multiple variables of the same type? 
eg.

Code: [Select]

x, y: integer = 0;instead we have to do

Code: [Select]

x: integer = 0;
y: integer = 0;

No, but there is an option to change them to a random value. (-gtt). This is for debugging though.

In general, initialization a variable is considered an action rather than a declaration, so something for the program, not the declaration block. Iniitalized variables are a later (D4) addition and borrowed from VB

Note that global integer variables (heap allocated) ARE in fact initialized to 0, afaik.
Local variables (stack allocated) are not.

I think objects have their fields set to zero on Create.

I think objects have their fields set to zero on Create.

Classes have, objects have not.

Managed types (ansi and Unicode strings, dynamic arrays, non-Corba interfaces), global or not, are also initialised by compiler-inserted code, I believe.

I meant the object that is created by instantiating a class. (Not the old object type.)
