Hi,

Not wanting to start another huge thread, but is there any way I can get the address of the string pointer, not the string.

So imagine you have a$="foo". @a$ will give you the address of the f character. Is there any way to get the address where the a$ pointer is located?

My main interest in this is with arrays, since

@array$(0) gives you a pointer to the first string in the array, and not the start of the array.

Thanks.

Look at this:

Code: Select all

string.s = "Hello"
location_of_string = @string
location_of_pointer = @location_of_string

Debug string
Debug Str(location_of_string)
Debug Str(location_of_pointer)

Debug PeekS(PeekL(location_of_pointer))

No, that was wrong, because it makes a new pointer
(location_of_string), and does not show the original pointer

It seems to be the same as in C:

Dim a$(2)
a$(0)="0line"
a$(1)="1line"

Debug a$() ;address of array
Debug @a$() ;..the same
Debug a$(0) ;string
Debug @a$(0) ;address of start of string

Is it this what you mean?
