/sys$common/syshlp/helplib.hlb DCL Tips, Expression, String  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The operator with the highest precedence in an expression is
    evaluated first. Following this, the next highest operator
    precedence is evaluated, and so on. Operators with the same
    precedence are evaluated from left to right, as they appear in
    the expression.
