(TOS)
None
The TOS value is pulled off the return
stack and is discarded. The TOS value
then becomes the previous value that
was pushed onto the return stack.
This instruction is provided to enable
the user to properly manage the return

This instruction allows the user to
implement a software stack by
modifying TOS and then pushing it onto
the return stack.
