(sorry for following up to myself) I had a look into the files, and the system comes with commented source code in assembler. FWIW this is a full distribution, including development environment (C, Cobol, Fortran-77,..), editors, kernel, VSAM database, etc... all of it with source code and documentation, From my first cursory look most of it is written in assemble, comes with sample test code and is documented enough to be understandable. The pascal, cobol and fortran 77 compilers are written in pascal (!), the C compiler is written in assembler. It looks like the environment must have been only vaguely UNIX-like but yet I find it mesmerizing enough considering where it ran and when. It adds another dimension to understand the impact UNIX had and how it spun off lookalikes and sprung the imagination of developers of the time expanding its heritage sideways. j -- EMBnet/CNB Scientific Computing Service Solving all your computer needs for Scientific Research. http://bioportal.cnb.csic.es http://www.es.embnet.org
