NAME
        MatchToolValue - check a tool type variable for a particular value.

   SYNOPSIS
        result = MatchToolValue(typeString, value)
          D0                        A0        A1

        bool matchtoolvalue(strptr, strptr);

   FUNCTION
        MatchToolValue is useful for parsing a tool type value for
        a known value.  It knows how to parse the syntax for a tool
        type value (in particular, it knows that '|' separates
        alternate values).  Note that the parsing is case insensitive.

   INPUTS
        typeString -- a ToolType value (as returned by FindToolType)
        value -- you are interested if value appears in typeString

   RESULTS
        result -- TRUE if the value was in typeString else FALSE.

   EXAMPLE
        Assume there are two type strings:
            type1 = "text"
            type2 = "a|b|c"

        MatchToolValue( type1, "text" ) returns TRUE
        MatchToolValue( type1, "TEXT" ) returns TRUE
        MatchToolValue( type1, "data" ) returns FALSE
        MatchToolValue( type2, "a" )    returns TRUE
        MatchToolValue( type2, "b" )    returns TRUE
        MatchToolValue( type2, "d" )    returns FALSE
        MatchToolValue( type2, "a|b" )  returns FALSE

   NOTES
        icon.library V44 skips blank spaces surrounding the typeString
        options and the value string. Older icon.library versions did
        not support this.
