I still remember seeing the manuals for BLISS in the system manager's office. Where I was studying programming (Northern Rivers College of Advanced Education, now Southern Cross University), we started off with a VAX 11/750 and then a Microvax.
While I was learning about COBOL (and, on the side, FORTRAN and DCL (DEC Command Language), the BLISS manuals beckoned. Sadly (very sadly!), I never took them down, never tried to type, compile, link and run the examples.
