This code:

class SubString : public NIHCL {
	char* sp;		// substring pointer 
        unsigned sl;		// substring length 
	String* st;		// String this is a SubString of
...
}

...
inline SubString::SubString(const String& s, unsigned pos, unsigned lgt)
{ 
	sp = &((String&)s).p[pos];
	sl = lgt;
	st = &(String&)s;
	checkSubStr();
}
...

generates the error

String.h: In method `SubString::SubString (const class String&, unsigned
int, unsigned int)':
In file included from Class.c:37:
String.h:227: references are not lvalues

I assume that this error comes from trying to take the address of s cast to
a String&.  This seems perfectly proper to me (and to Borland C++ 3.0);
since s is a reference type already, &(String&)s should return a String*
pointing to s.

What logic are you using to say that references are not lvalues?  The fact
that references ARE lvalues is the reason for returning type& from a
function rather than just type&.  I really don't understand the reasoning
behind this error.
