Re: Passing Parameter as Variable vs as address of variable

Hello Vern,

When a parameter is passed from RPG, it will be passed by reference by default. In this case, there is no copying of the variable contents to another address, so no time taken to duplicate anything.

That's how I understood.

That is the danger of passing a pointer by value.

Understood. Barbara explained that earlier.

In another exchange here, you asked, why was BY VALUE added? The reason is, certain system APIs and Unix-style functions require it.

Makes sense.

Thanks to you and Birgitta, many things are much clearer now!

:wq! PoC
