[HECnet] Reading RT11 files under Windows or Linux

Note I have not used (or compiled) it since we last ran it on our 11/60 and 11/70 at Tektronix. If I recall it had some support for tapes, in it but we did not have any on common tapes between the RT-11 machines and the Unix boxes, so I have not memory if any of that worked. It does have a nasty flaw in that it uses the UNIX raw disk interface and blindly assumes the RK05 is RT-11 format when it's writing the catalog. In fact, this is the program I used to famously wipe out Fred Park's life work one afternoon as the 0 and 1 keys were next to each other on one of the Tek keyboards and I hit the wrong one.... That said, it's really simple code, so if you were to do a 'sed script' changing of 'int' and 'register' to 'short' and then add function prototypes for all the functions, I bet getting it to compile would not be a huge issue. You might have look at some things like stat(2) and seek(2) which changed, but I would expect it to be pretty straightforward [frankly moving the man page to modern format is probably more work than the C code itself]. Send me an email offline, and I can make it available. Clem 1] I was recently looking for something else and thought I had seen it among some old CMU/Tektronix stuff [did not find what I was looking for on that crawl but ...] 2.] So the code is really old ... i.e. pre-K&R (White Book/Typesetter C *etc -- *no stdio - just read/write) as Dennis wrote the white book using V6 and it described the compiler that was released at that time we all tend to call 'Typesetter C' - which was the first edition of stdio [or as it was called then libS.a]. ?
