R: CALLPRC with RTNVAL

[Finucci Domenico <Domenico.Finucci@xxxxxxxxxxxx>]

Could it belong from null termination ?

That might be because of the 16-byte pointer thing. And everything in CL is
by reference, i.e., by pointer.

But that doesn't seem to explain why a CL program can't handle a character
array from C. I mean, when you've declared

char rtnval[4]
  and use

return(rtnval)

it's returning the pointer to the start of that array, which is actually a
pointer, after all. And when the article says to use a struct (which DOES
work), you don't declare a pointer to a struct, you declare a struct. So
there must be some special understanding between iSeries CL and C/C++
programs.
