Description

  • STOP used in the QBasic IDE does not close any files or go to the operating system. It returns to the IDE.
  • In the QB64 compiler, STOP closes the program window and returns to the IDE when the code is compiled from there.
  • STOP is ONLY used for debugging purposes and should not be used to exit programs!
  • STOP can also be used to suspend an event trap in the following statements: KEY(n), STRIG(n) and TIMER(n). The trap can be turned back on with ON and returns any trap events since STOP was used.
