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

    The following qualifiers affect what output is seen when a
    watchpoint is reached:

       /[NO]SILENT
       /[NO]SOURCE

    The following qualifiers affect the timing and duration of
    watchpoints:

       /AFTER:n
       /TEMPORARY

    The following qualifiers apply only to nonstatic variables:

       /INTO
       /OVER

    The following qualifier overrides the debugger's determination of
    whether a variable is static or nonstatic:

       /[NO]STATIC

                                   NOTE

       On VAX systems, watchpoints set on variables whose addresses
       are in global sections do not work. Attempting to set a
       watchpoint on a location in a global section results in a
       %DEBUG-E-BADWATCH message.
