ISPF provides special facilities for testing dialogs. The Dialog Test option allows testing of individual dialog elements and complete dialogs.
After a program has been developed, you can either assemble it or compile and link it using either the Foreground or Batch option. The Foreground option allows you to watch the program being compiled. The Batch option frees the terminal, which helps when you compile a long program. If errors occur, you can use the debugging capabilities of the Dialog Test facility to correct them.
