Setting a Basing Pointer

You set or change the location of the based variable by setting or changing the basing pointer in one of the following ways:

• Initializing with INZ(%ADDR(FLD)) where FLD is a non-based variable
• Assigning the pointer to the result of %ADDR(X) where X is any variable
• Assigning the pointer to the value of another pointer
• Using ALLOC or REALLOC (see ALLOC (Allocate Storage), REALLOC (Reallocate Storage with New Length), and the IBM Rational Development Studio for i: ILE RPG Programmer's Guide for examples)
• Moving the pointer forward or backward in storage using pointer arithmetic:

  EVAL        PTR = PTR + offset

  ("offset" is the distance in bytes that the pointer is moved)
