DATA g_ref TYPE REF TO char10.


Now we can write like:

g_ref->* = 'xyz'.

But how we can do with 'g_ref'?

Is there anythin like p++ in C?

Hi, thank you for the reply.

REF type is a little bit diff from pointer.

I only know dereference it by g_ref->*, but  how can I use g_ref itself?

Hi Ming,

As far as I know,

Reference variables are initial when you declare them. They do not point to an object. You cannot dereference an initial reference variable. A data reference variable can point to a data object if you

·  Use it to create a data object dynamically.

·  Use it to get a reference to a data object.

·  Assign an existing data reference to it from another data reference variable.
