MsgBox Statement Example
This example displays a message box that asks the operator if he/she wants to continue or not. The message box will display two buttons: Yes and No. A question mark icon will also be displayed. After MsgBox returns (after the operator clicks a button), then the answer is examined. If it's no, then all tasks are stopped with the Quit command.

Function msgtest
  String msg$, title$
  Integer mFlags, answer

  msg$ = Chr$(34) + "Operation complete" + Chr$(34) + CRLF
  msg$ = msg$ + “Ready to continue?”
  title$ = "Sample Application"
  mFlags = MB_YESNO + MB_ICONQUESTION
  MsgBox msg$, mFlags, title$, answer
  If answer = IDNO then
    Quit All
  EndIf
Fend
