able Format After Address Entry
If you select a data address of 040 for operand A, the EAF establishes a
data table format with four consecutive words as shown in Figure 14.2.
You can locate the result word anywhere in your data table. However, four
consecutive word addresses must be available. If you select an address of
060 for the result, the EAF automatically reserves 061, 062 and 063.
Be careful not to select data and result addresses so that they overlap.
