Maps are identified by a mapset name and a map number. The mapset name defaults to the program name, but you can specify a different one if you wish. General-purpose procedures such as CLICK are often shared amongst several programs. So, you might wish to change the mapset name to make it specific to your program. You may also opt to change the remarks mapname, which is the mapset for questions, messages and errors. Of course, if the main mapname and remarks mapname are different, your program may contain pairs of maps having the same numbers. This does not matter if the maps belong to different mapsets.
1. Select the Screen/Form design and create and new map
2. Double-click on the map to bring up its properties and ensure that the title bar box is unchecked
3. Create a static text field containing the message:
Click on OK or press Return any
key to continue...
4. Add a button to the map. Double-click on it to open its properties dialog. Make it a text button with the caption OK, give it field number 1, make it the default push button, make the associated key press <Enter> (so that clicking the button has the same effect as pressing <Enter>) and accept the other defaults.
5. Double-click on the map itself and in the Map Properties dialog set both the Rows and Columns to 1.
6. Save the map and exit the map editor.

7. In the Screen/Form set-up tab, select the map type as Pop-up Window. This is a temporary window that appears for only as long as it is needed.
Defining the Field Processing
Although the button is technically a field, there is no need to define any field processing.
