   This may be the ^^^^^^^^^^^^^ problem.  In iostream.h, form is 
prototyped as:

	ostream& form(const char *format ...);

which may mean form should require at least 2 args.  Does anyone have the 
spec on this?  I'm used to seeing things like form(char *f, ...) instead 
of form(char *f ...).  It seems like it should be ok as written, but...
Also, what is the output of the compiler.  Where is it balking?
