Hi All.

I'm is proffessional in C/C++, but I newbie in PASCAL (PPC).

I have some questions about using pointers.

1. Addressing arithmetic.

In C:

int* buffer = ...

* (buffer + 1) = 10;

2. Converting pointers to Integer and over

In C:

int *ptr = ...

int val = ...

val = (int) ptr;

ptr = (int*) val

3. NIL and procedure type

I save pointer to procedure in variable. Can I test this variable:

TYPE Proc = PROCEDURE;

VAR Ptr: Proc;

Ptr = SomeProcedure;

IF(NIL = Ptr) // not compiled

IF(NIL = Ptr^) // not compiled

IF(NIL = @Ptr) // compiled, but always FALSE, because @Ptr - address of variable (or not)

ps. Sorry for me english.

pps. Inserting code not working in my browser (Opera 10.5)
