John Pierce posted to comp.unix.questions on 1989-04-02, saying he'd written it "four or five years ago". Stu Heiss, in comp.unix.questions on 1989-03-06, said it was "posted to net.sources 18 Jun 86 with message-id 238(a)sdchema.sdchem.uucp&quot;. Unfortunately this isn't in the utzoo archive or the net.sources.mbox in archive.org's Usenet Historical Collection. A copy identical to yours was posted by Jim Harkins to comp.unix.questions on 1990-03-29. There's a later version, fixing a typo and some formatting and adding a mention of \f and \b in printf, which was posted by Brian Kantor to comp.doc on 1987-10-11 -- I've attached this. The same file (with two .bps commented out) was reposted in comp.unix.questions on 1989-11-16 by Francois-Michel Lang. Thanks, -- Adam Sampson &lt;ats(a)offog.org&gt; <http://offog.org/>
