Purpose

This routine is used to indicate that a speedbase field needs to be redisplayed by the window manager. This routine is normally used as part of the V- processing of a field when the value of the field being accepted has been changed by the code within the V- routine itself. Under normal circumstances the changes to the field would not be reflected on screen. Calling the ECHO routine ensures that the field is redisplayed before moving onto the next field in the window.

Exceptions

None
