Hello Rob,
You're trying to initialize a pointer to the address of a datastructure
whose address is based on that very same pointer.
You need to involve some actual storage to make it work: Define a variable
f.x.:
D RcvVar s 4096a
Then initialize all three pointers to the address of that storage location:
D pOBJL0100 S * Inz(%addr(RcvVar))
D pOBJL0200 S * Inz(%addr(RcvVar))
D pOBJL0300 S * Inz(%addr(RcvVar))
Best regards,
Carsten Flensburg
