Using Comparison Instructions
This chapter contains general information about comparison instructions and
explains how they function in your application program. Each of the
comparison instructions includes information on:
• what the instruction symbol looks like
• typical execution time for the instruction
• how to use the instruction
• how to enter the instruction
In addition, the last section contains an application example for a paper
drilling machine that shows the comparison instructions in use.
