(3) Precautions for using local pointers
(a) Program where local pointers are described
Local pointers cannot be used from other program jump instructions and sub-
routine CALL instructions.
Use an ECALL instruction to call a subroutine subprogram in a program file that
contains local pointers.
(b) Total number of local pointer points
If the total number of pointers (total for all programs) exceeds 4096 points, a
pointer configuration error (error code:4020) occurs.
