/sys$common/syshlp/helplib.hlb SCA, SCA Topics, Glossary, symbol_checks  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    A check that INSPECT performs on all occurrences of a symbol.
    For example, INSPECT can ensure that there are both read and
    write references to a variable. In this type of check, no single
    occurrence is either correct or incorrect. If there are problems,
    the problems are with the symbol as a whole.
