Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

' This example shows how the MSGBOX statement can be used to display messages
' or other information to the user. In addition to displaying information,
' the MSGBOX function returns a value indicating the button selected by the
' user. The DIM statement is used to share the value of a variable between
' procedures and the form module.
 
' When you run the example, select Command1 to see how the MSGBOX statement
' works and then select Command2 to see how the MSGBOX function works.
' Finally, click the form to display the value returned by the MSGBOX
' function.
 
' To try this example:
' 1. Choose New Project from the File menu
' 2. Choose New Form from the File menu to create a form with two command
'    buttons
' 3. Press Alt+F4 to return to the programming environment
' 4. Copy the code example below to the form module
' 5. Press F5 to run the example
