    The .LBR file is CP/M's old analog of the .ARC and .ZIP files for
PC, except that no _automatic_ data compression takes place in the .LBR
file.  It is possible to put compressed (*.?Q? and *.?Z?) files in a
.LBR file, but that is a separate step, and is not required.

    Try the following with NULU...   First, put the disk with NULU in
drive A:, then give the following command (the A> is CP/M's prompt):

A> NULU

    NULU is now waiting for your commands.  Put the disk that has
LUX42.LBR in drive A:, and a blank, formatted disk in drive B:.  Then,
try the following command: 

-O A:LUX42 -E B:*.* -X

    The -O command tells NULU to open A:LUX42.LBR, and the -E command 
tells NULU to extract all members to drive B:.  The -X command tells
it to close the library and exit the program.

    At that point, you should be able to do a "DIR B:" and see all the
files that got extracted.

    Another command you should try is the -F command, which puts NULU
into "filesweep mode".  It steps you through the members of a library
and lets you apply one-key commands to them.  For example:

A> NULU -O D:XYZ.LBR -F

    Also note in the above example that NULU commands can be spelled
out in the CP/M command line.

    I can't remember the exact command (perhaps -H?) but there is an
online help screen available.

    Sorry I can't help you with your Z80 SoftCard.

    Regards...    Darrell Pittman
