Noel, I did a quick look at that code. That is some of it for sure - looks like the parts in /usr/bin and maybe some of /usr/lib (MH was scatter all of the file system in traditional UNIX manner -- lots of small programs - each to do one job only - each fit in a small address PDP-11 just fine). The docs are missing and the MTA part is not there (which I think I remember was called 'submit' - but I could be very wrong on that). It's the second version because that code is using stdio, the first version used a Rand IO library, if I remember right (not the portable C library). Clem PS For all you younger readers to this list, you need to remember that for early C, I/O was specifically not defined as part of the language (in some sense it is still not), so many early programs had their own libraries and its a good way to date things. If the code is using stdio, it actually more 'modern' in the life of the PDP-11 [post 'typesetter C']. BTW: I can say, in the mid 1970s, I personally found the lack of defined I/O confusing when I was learning the language and (remember Dennis has not yet written the 'White Book' which was really part of V7). It was one of my bitches about C compared to BLISS, which was what I was coming and was a very rich system at CMU - while I/O in C was really a pain because ever program did it different - everybody wrote their own routines - which I thought was silly. Soon there after the 'portable C library' appeared and then with typesetter C, stdio. ᐧ On Mon, Jun 25, 2018 at 10:44 AM, Noel Chiappa <jnc(a)mercury.lcs.mit.edu> wrote:

Hi Jon, No, I don't think there's anything going back this far, e.g. no `pickup.c' in git, and I think David Levine, another maintainer, along with you and me, would like to expand the collection as he often looks back to understand the present. Clem, if you do dig out old MH source then please point the https://lists.nongnu.org/mailman/listinfo/nmh-workers list at it, or me directly if you'd prefer. Amongst nmh's current users is its co-author, https://en.wikipedia.org/wiki/Norman_Shapiro, and I don't think he has source that old otherwise he'd have passed it on. -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
