D/A field—Specifies whether the module data pointer is in a data or an address register.
module state is retrieved from the top of the stack, the caller’s stack pointer is
incremented by the argument count value in the module state.
Register field—Specifies the register number for the module data area pointer to be
0 — the register is a data register
