Date: Wed, 25 Mar 1992 11:42 EST From: s9274@srl1.LANL.GOV I found this interesting some years back, namely, that TI added (or left in) the documentation strings for nearly all of their functions. Surprisingly, nothing obvious (at that time, anyway) in TI's operating system made extensive use of the documentation. Why would the OS need to make use of it? They presumably did it for the *users*. barmar
