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

    The SHOW WATCH command displays information about watchpoints
    that are currently set, including any options such as WHEN or DO
    clauses, /AFTER counts, and so on, and whether the watchpoints
    are deactivated.

    If you established a watchpoint using SET WATCH/AFTER:n, the SHOW
    WATCH command displays the current value of the decimal integer
    n, that is, the originally specified integer value minus 1 for
    each time the watchpoint location was reached. (The debugger
    decrements n each time the watchpoint location is reached until
    the value of n is 0, at which time the debugger takes watch
    action.)
