Hint
• String comparison instructions are used to rearrange the order of text strings in order of ASCII. For
example, the ASCII order from lower to higher is the order of the alphabet from A to Z, so text strings
can be arranged in alphabetical order.
Precaution
• Place a right-hand instruction after these instructions. The String Comparison Instructions cannot
appear on the right side of the ladder diagram.
• These instructions cannot be used on the last rung of a logic block.
Example Programming
In this example, string comparison instructions are used to compare data.
