Greetings,

I was reviewing a manual pag= e update and came across an ambiguous answer to a question that came up, so= I thought I'd ask here.

execl and execv first= appear in our extant unix man pages in V4. The v3 and v2 man pages don'= ;t have this listed at all. Case closed, right? It appeared in V4.

However, the Dennis_v1/unix72 tree has execl.s=C2=A0and ex= ecv.s in them. Diving back into the history on Warren's github account,= =C2=A0h= ttps://github.com/DoctorWkt/unix-jun72/tree/master/src=C2=A0says they c= ome from:
"The files in lib/ come from the libc.sa file which is on the last1120c.tar.gz
= 
tap(I) tape image, =
also at the same URL, and form the C library for the
above compiler."
and
&q=
uot;from a working C compiler for 2nd Edition UNIX."

which suggests that it may have been in V2 or mayb=
e even V1. It's first use in Unix appears to be V5, but the extant pre-=
v5 code is so fragmentary it's hard to know for sure. It's not ment=
ioned in section II or section III of v1, v2 or v3.

Does anybody know for sure, or can provide more in=
sight into the last1120c.tar.gz file to help disambiguate?
