• Debugging programs will run much smoother if an END(001) instruction is
inserted at various break points between sequence rungs and the
END(001) instruction in the middle is deleted after the program is
checked.

A logical start is accomplished using an LD/LD NOT instruction. The area
from the logical start until the instruction just before the next LD/LD NOT
instruction is considered a single instruction block.
Create a single rung consisting of two instruction blocks using an AND LD
instruction to AND the blocks or by using an OR LD instruction to OR the
blocks. The following example shows a complex rung that will be used to
explain the procedure for inputting mnemonics (rung summary and order).
