Flow Control |

Several mechanisms can be used to control program flow to perform conditional or repetitive instructions or to improve structure and maintainability.

Statement References are sometimes an essential component for these types of procedures.

The PxPlus Structured SAVE feature can be used to verify the logical integrity of decision and loop structures automatically each time you save a modified program.

This section covers sequence control statements for repetitive execution, conditional execution and sequence overrides.
