In article <49044@yale-celray.yale.UUCP> spolsky-joel@CS.YALE.EDU
(Joel Spolsky) proposes the following routine to substitute for the
inability of Turbo C 1.5 "cprintf" to handle tabs properly:

		void tab()
		{
			while ((wherex()-1) % 8)
				cprintf(" ");
		}

I believe there is a problem with this routine.  If the cursor is
already sitting on a tab stop, it won't print anything at all --
whereas the correct thing to do would be to print eight spaces.

How about the following alternative version?

		void tab()
		{
			cprintf(" ");
			while ((wherex()-1) % 8)
				cprintf(" ");
		}

The only difference is the addition of a "cprintf" before the "while".
