Continuing on the topic of what to return from a string classes char *
operator.

We have defined the function as

'const char * operator char *(void);'

to attempt to avoid someone using the returned string and killing it.
Unfortunately, when we use it in a C funtion declared as

myFunc(char *arg1, char *arg2);

main()
	{
 	String s1("hello");
	myFunc("arg1",s1);
	}

the compiler (zortech 2.06?). does not issue any type of error message. Is
this correct? We were hoping it would complain about passing a const char *
where it wanted a char *, and thus notify the programmer that they need to
create a temporary variable...

p.
