Some of the files on this disk have the extension .LBR, these are
librarary files. They are actually composite files made up of a
number of smaller files. Before you can use the programs in them
they have to be extracted.

To extract the programs contained in libraries on this disk,  use 
NULU. The procedure is:

Put the disk with NULU in the A:  drive,  and a disk with room on 
it on the B: drive. Then enter

     B:
     A:NULU                      {start the NULU program}

Remove the disk containing NULU from the A:  drive and substitute 
the disk containing the library file you wish to extract programs 
from  (in  many  cases,  the disk with NULU will  also  have  the 
library file, in which case, just leave it in the A: drive). Then 
enter

     -o  a:<library file name>   {Open the library file}
     -q *.*                      {Extract and usqueeze all entries}

{all the extracted files will be put on the disk in drive B: }

There  are  many other options available with this fine  program, 
but the sequence above is all you really need to know.

To  unsqueeze compressed files that are not in  libraries  (files 
with a Q in the middle of the extension e.g. FILE.DQC), use NSWP. 
Tag  the  files with the 'T' command and use the 'Q'  command  to 
unsqueeze the files.
