Hi Grant, tput setf 4; date; tput sgr0 See terminfo(5). (BTW, I don't think the question is worthy of TUHS.) -- Cheers, Ralph.

Larry, as was stated in the original post (and multiple times in the replies), I believe they were looking for another solution. On 11/26/20, Larry McVoy &lt;lm(a)mcvoy.com&gt; wrote:

First we can find that FIPS-86 is "in whole" ANSI-X3.64-1979 https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub86-1981.pdf Thus giving us "free" access to the original ANSI standard in a "new" digital (PDF) form.

X3.64 also gives a good list of all the people and organisations which cooperated to create this standard (though interestingly only mentions ECMA-48 in that last appendix). There is also corroborating evidence of this cooperation in the preface ("BRIEF HISTORY") to the 2nd Edition of ECMA-48: https://www.ecma-international.org/wp-content/uploads/ECMA-48_2nd_edition_a… Note though that the link the 1st Edition of ECMA-48 here is wrong, so as yet I've not seen if there's any history given in that 1st edition): https://www.ecma-international.org/publications-and-standards/standards/ecm… As an aside, the DEC VT100 terminal was an early (it came out a year before X3.64) and relatively complete (for a video terminal application) implementation of X3.64. BTW, I would in general agree with Steffen that implementing an application to output anything but X3.64/ECMA-48/ISO-6429 is rather pointless these days, _unless_ one wants to take advantage of any particular implementation's additional "private" features, and/or work around any annoying but inevitable bugs in various implementations. Also the API provided by, e.g. libcurses, often makes for much easier programming than direct use of escape sequences, or invention and maintenance of one's own API. -- Greg A.
