III.    General Instructions.


        The   libraries   to   be   altered   are  "/lib/libf.a",
"/lib/filib.a", and (optionally) "/lib/liba.a".  Each library  is
described in its own section below.  "fp.o" in "/lib/liba.a" MUST
be replaced by the new "fp.o".   This  can  be  effected  without
changing  "liba.a"  by  placing  the  new  "fp.o"  at the tail of
"filib.a".  (This was done by us until we were convinced that the
new  fp.o  and  the new double-precision liba routines functioned
properly and thus could be let loose on even non-FORTRAN users.).
Libraries  may  be altered routine by routine with the "ar r ..."
command.  New libraries may  be  built  from  scratch,  and  then
"mv"ed  onto the old version.  Either way, be careful to maintain
the correct order of the object subfiles  of  each  library.   In
particular,  the new "/lib/filib.a" has two peculiar twists ("r6"
and "alog"&"exp" - see section on "filib").  For examples of what
to do, see the "unusual Assemblies" section.
