Library /sys$common/syshlp/dbg$help.hlb DEBUG, Language Support, SCAN, Controlling Execution, Watchpoints  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Note the following points about SCAN watchpoints:

    o  Variables declared at MODULE level are static by default.

    o  Variables declared at PROCEDURE or MACRO level are automatic
       (nonstatic) by default.

    o  DYNAMIC STRING variables are dynamically built. The storage
       used to hold the value of the string can change when the
       value of the string changes. Thus, the storage the debugger
       is watching may not be the correct storage if the string's
       value is changed.
