Syntax

── ? ─┬──────────────┬─┬─ BREAKPOINT ─┬────────────────────────────────%
      └─<mix number>─┘ └─ BP ─────────┘

Explanation

The ?BREAKPOINT command can be used only during a test session of the Test and Debug System. If used when running a program which is not a test session, a warning is produced, and the command has no effect. If the <mix number> is omitted and the station is not executing a program, the response is “#NO ACTIVE TASK.”

When used during a test session, the program being tested is suspended, and control is transferred to the Test and Debug System. For more information, refer to the COBOL ANSI-74 Test and Debug System (TADS) Programming Guide that addresses the language of the program being tested.
