SUBINVALIDSTR

Message        Parameter substitution produced an invalid string
               literal.

Description    In certain modes, the compiler will replace
               identifiers found within a string literal if they
               match a macro argument name.  This form of "old-style
               stringization" is provided for compatibility with
               older C compilers.  This message is output if this
               replacement forms an invalid string literal.

User Action    Modify the macro argument so that a valid string is
               formed.  HP also recommends that the macro body be
               rewritten to use the standard C stringize operator
               (#).
