Library /sys$common/syshlp/dbg$help.hlb DEBUG, Messages, OUTPUTLOST  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 output being lost, both NOTERMINAL and NOLOG are in effect

    Facility: DEBUG, VMS Debugger

    Explanation: The SET OUTPUT command has set the output conditions
    to NOTERMINAL and NOLOG; consequently, the output is not
    displayed on the terminal or written to a log file. The output
    normally displayed by the debugger will not be available.

    User Action: Use the SET OUTPUT command to send output to the
    terminal or to a log file.
