The effect of the NO-ECHO clause is to prevent data corresponding to a screen item that has been specified with the
NO-ECHO clause from being displayed on the screen. During the execution of an
ACCEPT Statement, the cursor will appear at the screen location that corresponds to an input screen item, but any data keyed by the terminal operator will not be displayed. For fields that are both input and output, the contents of the screen location of the screen item prior to the execution of the
ACCEPT screen Statement remain unchanged and are unchangeable by the terminal operator.
