<br>
Which revisions of the "C Reference Manuals" are known to be out there?<br>
<br>
<br>
I found this:<br>
<a href="https://www.bell-labs.com/usr/dmr/www/cman.pdf" rel="noreferrer" target="_blank">https://www.bell-labs.com/usr/dmr/www/cman.pdf</a><br>
<br>
Which seems to match the one from V6:<br>
<a href="https://github.com/dspinellis/unix-history-repo/tree/Research-V6-Snapshot-Development/usr/doc/c" rel="noreferrer" target="_blank">https://github.com/dspinellis/unix-history-repo/tree/Research-V6-Snapshot-Development/usr/doc/c</a><br>
<br>
"C is also available on the HIS 6070 computer at Murray Hill and and on<br>
the IBM System/370 at Holmdel [3]."<br>
<br>
<br>
But then there's this:<br>
<a href="https://www.princeton.edu/ssp/joseph-henry-project/unix-and-c/bell_labs_1369_001.pdf" rel="noreferrer" target="_blank">https://www.princeton.edu/ssp/joseph-henry-project/unix-and-c/bell_labs_1369_001.pdf</a><br>
<br>
"C is also available on the HIS 6070 computer ar Hurray Hill, using a<br>
compiler written bu A. Snyder and currently maintained by S. C. Johnson.<br>
A compiler for the IBM System/360/370 series is under construction."<br>
<br>
Due to the description of the IBM compiler, it seems to predate the V6<br>
revision.<br>
<br>
Both above revisions use the =+ etc operators.<br>
<br>
<br>
Finally, this version edited by Snyder:<br>
<br>
<a href="https://github.com/PDP-10/its/blob/master/doc/c/c.refman" rel="noreferrer" target="_blank">https://github.com/PDP-10/its/blob/master/doc/c/c.refman</a><br>
<br>
"In addition to the UNIX C compiler, there exist C compilers for the HIS<br>
6000 and the IBM System/370 [2]."<br>
<br>
This version documents both += and =+ operators.<br>
