Hans,

Last eMail forget it. It has been sent by error.

I'll try your solution mentioned below.

Thanks for your request.

Questions like this are best asked in the RPG400-L mailing list.

But to get to your question, I'm not really sure what you're asking,
so I might not have the answer you're looking for. Clearly, you
can't put string data into a pointer variable. So I assume you have
a pointer to some string data and you want to insert into that area.

*If* you know the full extent of the particular storage pointed at
by the pointer, you can define a BASED character variable based on
that pointer, and then you can manipulate that BASED variable. You
can use the %REPLACE built-in function to insert text into some
string by specifying 0 as the 4th argument.

That is, if you know your pointer points at an area of, say, 100 bytes:

D bstr        s              100a   based(ptr)
  /free
      bstr = %replace('char to insert':bstr:startpos:0);
  /end-free

But I'm not sure if that really does what you want. If not, please
provide more detail of what you're trying to do and follow up on
RPG400-L.

Cheers! Hans
