Re: Pass by value and reference

USE subroutines AS below.

perform <subroutine name> using <p1>

                                        changing <p2>.

form <subroutine name> using value(u_<p1>) type <type name> " pass value

                                    changing value(c_<p2>) type <type name>. " pass reference

<code>

endform.

the above is best practice for subroutines.

pass values are declare as using value.

pass reference are declare as changing value.
