You were and you still are. If you conult Princciples of Operation you
will note that it never refers to the displacement as an address, but
instead talks about how the processor *generates* an address from the
displacement.

When did you drop out of the communist party? What? You claim you
never belonged? Well, I never said that the loader adjusts
displacements. As to relocatoable addresses, see p. 98 of SY28-6659-7,
which states "Changes the values of address constants in the loaded
program from relative addresses to absolute addresses."

When I specify an address constant of A(16), what action does the
loader need to take to adjust it? The assembler documentation clearly
spells out the difference between relocatable and nonrelocatable
values.
