The router program is no longer in the library list when control is returned to the caller, program A.

That couldn't be it though.
Could it?

Hi, I thought I had pointers sussed, but it seems not. Hope
someone can help.

I'm calling program B from program A via a router program
with a pointer in and out as parameters.
I've debugged and I can see that program B receives a value
*NULL for the output parameter pointer. It initialises the
pointer, it is returned to the router OK, but once back in
the calling program A, if I do EVAL on the pointer, I get
CPF8E17, Pointeur non défini pour l'emplacement référencé. (
would someone give me the English version of that message? ).

Then, when I try and use the DS based on the pointer, it says
I'm trying to access something that no longer exists
(MCH3402). I wonder if the problem is not the pointer but the
fact that the router program has ended?

I've already successfully tested program B, using a test
program to call it directly, now I'm testing with the router.

Thanks.
