This really depends on the OS and the compiler used.  In Windows and OS/2
(probably other OSes too, eg. MacOS & BeOS) it's possible to have
resources that you can bind to an executable.  You can have string tables
(and icons, bitmaps, etc.) which can be shared by multiple instances if
they are marked "sharable". I don't think this applies to strings
within the source code though (but I suppose in theory it could, but might
slow things down a lot).

Of course, in the case of such a string placed in a DLL, multiple instances
of a program that load the DLL will share the memory where the string is
held (which is why you have to be careful when writing shared libraries).
