Specifying a variable message field

Programs frequently require messages to provide feedback to users concerning errors or other special conditions.

You can use the EZEMSG special function word and a map variable field for presenting messages to users. When you use EZEMSG, you should provide a variable field long enough to contain the text of the message.

To specify a variable message field:

  1. From the Palette, select the Variable part Figure variable not displayed..
  2. Move the mouse pointer to line 15 and click in column 1 on the map presentation area.
  3. On the General tab, in the Name field, type ezemsg.
  4. In the Length field, type 78.
  5. Select OK.

While you are defining a map, you can change any of your previous definitions. For example, you can change the length of a variable field or the text and position of a constant field.

To change the specifications for a constant field or a variable field, double-click on the field, make the necessary changes in the properties window and select OK.

To change the content of a constant field, you must enter edit mode. To enter edit mode press and hold the Alt key and, click mouse button 1 in the field where you want to make a change. You can type over the text or cut and paste text using selections from the Edit menu. To select text to cut, copy, paste, or delete, with your cursor in edit mode, click to the left of the text you want to select. Drag the mouse pointer to the right until the text you want to change is selected. Release the mouse button. From the Edit menu select the appropriate menu choice.
