How To Use Library Files
by Ric Stilfield
What is a library file, you ask? Well, it's a collection of files that
are usually related that have been put in one file with extension LBR. A
lot of these files inside a library file are squeezed or crunched. This
whole process serves to save space and keep f ilea that are related
together. You will usually find these files on PD software.
You will need some programs to get these files into a useable condition.
They are NULU15.COM and UNCR.COM or DELIB.COM, UNSOUEEZE.COM and
UNCR.COM. (These are all on MOAUG CPM/PD Vol. 1).
Let's talk about the easier to understand method first.
First, FORMAT and SYSGEN A blank disk or DDP. Second, copy or PIP the
.LBR file, DELIB.COM, UNSQUEEZE.COM and UNCR.COM from their respective
source disks to the blank formatted and sysgened disk.
Remove all other media from your system and log on your new disk (^C).
You might want to check the DIR to make sure you have got the right
Type in DELIB. You will be prompted for the library name.
ENTER LIBRARY FILE NAME:
Type in the name of the Library file and hit Return. You will see the
message: EXTRACTING FILE *.* This will continue until all of the files
have been extracted. After this process is complete get a DIRectory
(there should now be more than the four original files listed).
Look through the list to see if any of the files are squeezed (those
that contain a Q in the middle of the extension). Type in USQ followed
by the file name and hit RETURN, i.e: USQ WID30.DQC
You get a readout somewhat like this: WID30.DQC ------- >WID30.DOC
Follow this procedure for all squeezed files.
Next you want to uncrunch all the files that are crunched (All those
files containing a Z in the middle of the extension.) All you have to do
for this is type in UNCR it will automatically search for crunched files
and uncrunch them. There is a pretty strange display when this program
is operating but You do not need to worry about it as long as it works.
Next month we will discuss NULU-15. It is a little more complicated to
use, but has more features. Here are some examples of crunched and
squeezed and library files. Hopefully this will help you to recognize
