Machine Instructions and Stack Operations
The Condition Code is set to pattern C as a result of the compar-
ison of the TOS with the content of the effective address loca-
tion. The TOS is then deleted.

Mode and Displacement
The contents of the effective address memory location (E) and the
succeeding location (E + 1) are pushed onto the stack. The con-
tent of E, the most significant word, is loaded into B; the con-
tent of E + 1, the lea st significa nt word, is loaded into A. If
indirect addressing is used, the word referenced by the initial
address (base + displacement) contains a DB+ relative word ad-
dress. If indexing is used, the effective address is obtained by
adding twice the contents of the Index Register to the relative
word address.
