Window and Display Features

Example

This example illustrates the following features:

This example uses two windows, FIND and ED. The FIND window instructs you to enter a name. Then a data set is searched for all the names starting with the entered value. If no observations are found, you receive the following message:

   Not found, enter request
If any observations are found, they are displayed in the ED window. You can then edit all the fields. If several observations are found, you need to use the scrolling commands to view the entire display surface. If you enter the SUBMIT command, the data are updated in place in the data set. Otherwise, you receive the following message:
   Not replaced, enter request
If you enter a blank field for the request, you are advised that EXIT is the keyword needed to exit the system.
