error occurred while executing routine called from exception break

    Facility: DEBUG, VMS Debugger

    Explanation: While executing a routine called from an exception
    break using the CALL command, an exception occurred. Any
    exceptions from routines called from an exception break cause
    this message to be displayed followed by the text of the
    exception. Execution of the called routine is then terminated.

    User Action: Either correct the CALL command if it was in error,
    or correct the routine that caused the exception. To use the
    debugger to help find the cause of the exception, try calling the
    routine while not at an exception break.
