Bound program access

Built-in number for CPYBYTES is 9.
CPYBYTES (
          target_string   : address of aggregate(*)
          source_string   : address of aggregate(*)
          copy_length     : unsigned binary(4,8) value which specifies the
                            number of bytes to copy
)

Description: A copy from the storage specified by source string to the storage specified by target string is performed. Copy length specifies the number of bytes to copy. It is assumed that sufficient storage exists at the locations specified by source string and target string.

Pointers cannot be copied using this instruction.

Undefined results can occur if the storage locations specified by target string and source string overlap.
