Subject: Re:library files
Status: R

Here are some examples that will help explain the lib library utility.

The -v flag means be verbose; everything that's done print it.

To create a new library:

lib newlib -rv file1.o file2.o file3.o

The object files are also called modules; that is they are assembled
and/or compiled and not linke.  The addresses in the modules are said
to be relative.  The modules can contain any number of functions or
subroutines.  If one function in a module is needed, the module is
added to the linked file, not just the function.  rt65.o is an example.

You can take the file names from a file:

lib newlib -rvi list

and the file list contains the names file1.o file2.o file3.o.

The -r flag can also be used to add modules to a file.  The -r flag
means replace.  If the module is not in the library, the module is
appended to the end of the library.  A module may be placed before
another module in the library with the -b flag.

lib newlib  -r new1.o -b file2.o  will place new1.o before file2.o
in the library newlib

You can delete modules with the -d flag and extract modules with
the -x flag.

You can experiment on a copy of libc and see what the different
flags do to it.  Make sure you use a backup.

I used the lib function to add scanf.o to libc before atoi.o
with the command:

lib libc -rv scanf.o -b atoi.o (I think!)

I've extracted the modules fp65.o and elems65.o from libc for my
own dastardly purposes.

lib libc -xv fp65.o elems65.o

Extracting a module doesn't delete it.
