D Allen's re-write of the Tenex csh to fix the bugs and extend it to some features that he and others in the Math Faculty Computing Facility (MFCF) at the University of Waterloo wanted (itcsh) - Iain!'s office was a few doors down the hall from mine. Anyhow, in that environment of 20 years ago, csh, tcsh and itcsh were the only ways to get beyond the limitations of the original Bourne shell, and was something of a de facto standard, at least until the arrival of the Korn shell, Perl, and many other scripting systems in the times since. The attitude of the time was an anticipation that the Bourne shell would likely be superceded - it was around for those running strictly System V systems. -- Mark L.
