Hi Barbara,
The procedure was called by another module, but it was also called internally. And when sombody changed the procedure interface, he forgot to change the prototype. Before that somebody else forgot to include the /copy with the prototype to the module containing the callee. Everything compiled fine, but the call from the external module did not work because of a parameter mismatch. The last parameter contained nothing but garbage and I wondered why.
I took me too long to find the problem, because I did not think at the prototype.
Opening a RFE is a good idea.
Thomas.

That's true of a module that is calling a procedure in another module.
But a prototype isn't required within the module that is exporting the procedure.
Thomas, the reason that the compiler doesn't require a prototype is that it the procedure may not ever be called from another RPG module.
It wouldn't be possible for the compiler to change its rules and start requiring a prototype for exported procedures. But you could open an RFE to request an H spec option to require prototypes for programs and exported procedures.
