Entry and Display of Input and Result Values
You can monitor the values in the Operands and Result words by entering
the instructions shown in Figure 14.3. This figure shows one method for
monitoring input and result values of an EAF instruction.
The shaded portion is called a primary ladder diagram. It contains
Operand B and an EAF block. You can have as many as 4 Gets in this
rung to select Operand B and they need not be consecutive data table
addresses. Any rung conditions must be at the beginning of the rung.
Nothing except a Branch End can be between the Gets and the EAF.
Operand A must have four consecutive data table word addresses. They
can be stored anywhere in your data table.
