Optimization of Message Handling

The following topics are covered:


Screen Output Handling

Natural provides an extensive message optimization capability. Prior to sending an output screen, Natural determines which portion of the screen has been modified; only data which have actually been modified are sent.

This is to be considered when, between two successive terminal outputs, portions or the entire terminal contents are changed

This is particularly true if a subprogram called from Natural by an external CALL interface produces dialog output.
