Subject: NULU10 - a machine language alternative to LU

A machine language alternative to LU (the Library Utility program that
makes .LBR files) is now available from SIMTEL20.

Filename			Type	 Bytes	 CRC

Directory MICRO:<CPM.CPMLIB>
NULU10.COM.1			COM	 14336  63C1H
NULU10.DOC.1			ASCII	 40770  91E0H
NULU10.HEX.1			ASCII	 34899  255BH

...and the whole package for those who can FTP ITS-binary files:
NULU10.LBR.1			COM	 38272  D7CEH

Here is an excerpt from the author's .DOC file:

NULU  is  offered  as a complete replacement for LU  and  LSWEEP.  
Weighing  in  at 14k,  it includes nearly all  features  of  both 
programs and then some.  It features:

	Two operation modes with a full menu for each
	Viewing  and printing of member files,  unsqueezing  when
                necessary
	Extraction of member files with an option to unsqueeze
                where appropriate
	Bigger libraries, up to 800 members or more depending on
                available memory
	Automatic member sorting, all members kept sorted at all
                times
	Faster reorganization
	Enhanced error handling
	Access to deleted members
	Optional read only mode
	General compatibility with LU and NSWEEP syntax
	Numerous user patches

I  am aware of only one thing that LU does that NULU does not do.  
LU  maintains  a  CRC for each member file and  for  the  library 
directory  as a whole.   NULU doesn't do this at all.   In  fact, 
NULU changes these CRC bytes to 00 as soon as it gets the chance.  
In case you still want or need to run LU on a library modified by 
NULU, LU will simply regard it as a library created by an earlier  
LU version and will promptly set CRC's for the various members.

To the best of my knowledge,  NULU will run on any system running 
CP/M  2.x  or  higher,  however it has only been  tested  on  the 
Osborne  1  and the Osborne Executive computers.   It is  written 
entirely in 8080 assembly language.
