I have already posted this in another thread (on non-BTL C= compilers), but it's more relevant=C2=A0here. My 1985 review of Cohere= nt for BYTE Magazine:


I see that I went into some detail. For example:

And= this, although I'm sure there were incompatibilities I didn't unco= ver:

"Coherent has all the Version 7 system c= alls except nice (which sets a process's priority). and they seem to be= used in the same way. It should be easy to port C programs between Coheren= t and UNIX Version 7."

On the whole my re= view was very positive.

Sorry, just to clarify: I meant I had no idea Dennis's posting about the event happened so late; by 1998 USENET was basically overrun by
spam. Obviously, the inspection trip had happened much earlier.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 - Dan C.
