aareadme in case/gen/ver_8 (no longer in case/93su523/gen/base):  RJL 94/12/6

Rev 94/12/6: Makefile points to a non-existent BIN-DIR so I changed it - RJL
Problem: sccs edit + sccs delta unable to create lock file on SCCS.
	Either someone else has it checked out or I am fogetting
	something that enables sccs to work for me. It's been a long time.

Rev. 94/5/4:  I revised gen/ver_8/doc/chgen_manual8.tex tonight,
to correct an error in gen v8 documentation  that JMolloy reported 
in the 93f523/93fsym/base/doc final report:

The error is in defining arg3 of pr_find as a string-valued key field. 
From gen v7 on, it should be a value of type hcg_key (unsigned int).
Passing XXcurr->XXid is OK since that is also type hcg_key.
Passing a char[8] value like "XX000001" is wrong; it should be
decoded by decode_rtnstr("XX000001"). 

Caution: don't use decode_retstr more than once in an arg list:
Declare temporary unsigned ints and use decode() to return their values.
(See gen/ver_7 and gen/ver_8 user guides.)

----------------------------------------------------------------

I copied the directory /usr/proj3/case/93su523/gen/base
and then removed the contents of /usr/proj3/case/93su523/gen/base.

Other subdirs of the genv8 team were not disturbed under 
/usr/proj3/case/93su523/gen, but will be removed when space requires it.

WARNING: src/* files are dated a week earlier than src/SCCS files.~
 
$CASE/gen/ver_8/aareadme.dec94 says this:
WARNING: lut.h is called-for  in the Makefile but is MISSING from src/*.h
This is because lut.c is generated via the makefile from an intermediate
file gen_lut.c; similarly with gen_lut.h I believe.

New SUbj: key_t was replaced by hcg_key in olcarch and in gen/ver_8.
For some reason it is still key_t in gen/ver_7/src/SCCS/s.gen_defines.c
It appears from fr.tex of  project /usr/proj3/case/93su523/gen/jpowell(?)
that hcg_key replaced a simple char*[9] declaration not key_t.
There is mail about  this on eagle that I can't find yet. - RJL 94/5/10.
