Data Table Format After Address Entry
Be careful not to select operand (data) and result addresses so that
they overlap.

Entry and Display of Input and Result Values
Figure 15.3 shows one method for displaying operand (data) values and the
result values of an EAF, not using the default address (010) as the Data
Address inside the EAF instruction. The first branch contains the Result.
The second branch contains the Operand. Addresses of the Operand do not
have to be consecutive (if the Data Address in the instruction is 010).
