A few experiences as SNOBOL/Icon enthusiast, not expert, ending with limited tie back to Unix:

o Introduced to SNOBOL4 in introductory programming languages course summer 1971 U.T. Austin

o ca 1976 used SNOBOL4 on VM/370 to build Fortran to PL/I translator "The elapsed time between beginning work on the translator and getting a running PL/I version of APLOMB was approximately two weeks, and this achievement was a great relief to those who anticipated a much, much larger effort." https://technologists.com/sauer/The_Evolution_of_the_Research_Queueing_Package.pdf

o ca 1985 (with minimal effort) modified/built Icon to run on PC/IX, began emailing with Ralph Griswold

o Discovered IBM colleague Viktors Berstis and his SNOBOL advocacy/expertise (http://berstis.com/)

o ca 1986 "With help from an ISC colleague, I created a PL.8 to C translator using Icon, that was used to facilitate some of the rewriting. [of the RT/PC VRM]" https://notes.technologists.com/notes/2017/03/08/lets-start-at-the-very-beginning-801-romp-rtpc-aix-versions/
