@            VMS / L&T  SIGs Fall 2004 Tapes Initial Documentation    H ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE **  @ 	Due to publicity about Trojan horse programs, computer viruses,@ 	and similar hazards, there may be increased risk that such code1 	may have been submitted for the symposium tapes. B 	   Neither your librarians, DECUS, nor DEC has detailed knowledgeA 	of the programs herein. The risk of using code here is YOURS and B 	you should consider yourself WARNED that you should test programs? 	yourself to determine what risks they may pose. The cataloging C 	process consists of assembling documentation and files into usable 5 	formats, but does NOT involve testing the programs.    C 	   Your librarians make use of many programs from symposium tapes, ? 	however, and none of this code contains any known problems. We D 	ask that if you notice something suspicious about any DECUS programA 	you attempt to help by reporting the problem to the DECUS office 6 	immediately and by diagnosing it as well as you can. @ 	   In using this code, please be aware that privileged code mayC 	contain operating system version dependencies whose effects should C 	be assessed before running it. The system crashes you avoid may be 
 	your own.@ 	   The DECUS library may be contacted at 1-800-332-8755. Please: 	ask that Ann Foley and Glenn Everhart (your librarian) be? 	informed of the problems. (If possible, leave a phone number.) ? 	(The phone number may be easier to remember as 1-800-DECUS55.)   @ 	   You can reach your librarian (Glenn Everhart) on Internet at 	the network address 		Everhart@GCE.Com. 	if you wish faster contact or have questions.B 	   Thank you. Our greatest security against this kind of nonsense  	is watching out for each other.  H ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE ** NOTICE **    D 	This directory contains general documentation for this and previousH tapes and an index.  It is intended to replace previous distributions of? [VAX000...] but there may be some older files you want to keep.   ? 	The tapes this time are combined VMS SIG and L&T SIG tapes, to = reduce duplications between the two collections. The 96BVMSLT ; directory is the master index directory for the entire set.   E 	The top level description summary to the Spring '01 VMS/LT SIG tapes C is contained in ABSTRACT.DOC and VMSLT01ATPE.DOC in this directory. : For a longer description see AAAREADME.*, the concatenatedE AAAREADME.TXT files from the respective submissions.  AAAREADME.TXT's K back through the Spring 1979 tape are in a sub-directory [.OLD_AAAREADME].    D 	The tapes are in VMS Backup format in three save-sets: one each forB [99BVMSLT...], [VMSLT01A...], and [DECUSLIB...].  The first is theM index saveset (01AVMSLT), comprising around 20000 blocks.  The others are the K DECUS library catalog in machine readable format (DECUSLIB) and the VAX/L&T % collection for Spring 2001 (VMSLT01A)   6 	Some files have been compressed this time where space? use needed to be reduced. Tools for decompressing the files are > found in [01avmslt.tools...]; the AAAREADME files in that area will tell how to use them.E   Compression was done using Gnu COMPRESS, ZOO, ZIP, LHARC, and GZIP, < all of which will function also on other machines than VAXen9 (including Unix boxes, PCs, and Amigas). Where VMS Backup > savesets were compressed, the filenames encode the block sizes= so that a file mumble.bck_8192_Z needs to be decompressed via  $ compress -d mumble.bck_8192 > and subsequently be turned into fixed record length 8192 bytes' per record with a command to FILE like: > $ file/type=fixed/record=8192/attr=noimpliedcc mumble.bck_8192> At this point, mumble.bck_8192 is a normal VMS Backup saveset.< See file Compressions.Txt and Decompress_all.com for further/ information on unpacking compressed files here. ? 	Most files that are compressed are compressed with Zip so that ? VMS file attributes return automatically. To uncompress, define  unzip as a command, e.g.  $ $unzip:==$disk:[01Avmslt.tools]unzip   and unzip with the command   $ unzip filename.zip  E (The unzip -v filename.zip command lists the contents of the zip file $ and unzip -h  will print some help.)    A 	Some files are given extensions like .TAR_LZW or .TAR_Z or .TAZ. H These are generally images of compressed TAR savesets from Unix systems.G (That is, WE don't make these; they are made on unix systems.) The same ? goes for the GZIP compressed files from FSF. Files of type .tgz 3 or names of something_tar.gz are gzipped tar files.   E Use the COMPRESS utility to convert to tar files, then use TARREAD23A < to pull the tar files apart. The commands are something like  D $compress -d file.tar	!where filename must originally be file.tar_z;$ 			! rename it to this if necessary. $assign file.tar tape: $tarread23a xv  < to extract everything into the CURRENT directory. Define the6 tarread23a verb to run that image as a foreign commandD (e.g. tarread23a:==$tarread23a   with tarread23a.exe in sys$system.)  E 	You will run accross .ARC or .ZOO or .LZH files on some directories. M For those of you not familiar with these, they are excellent file compression J and archiving programs that are widely used in the microcomputer world forB distributing programs via floppy and bulletin boards.  You can useF [.TOOLS]VMSSWEEP (or ARC in the same directory) to read ARC files on aF VAX, or ZOO to read ZOO files on a VAX. ZOO files MUST be in STREAM_LFB format to be read by VMS ZOO, but should be converted to fixed 512E bytes, no carriage control to transfer to a PC. Your librarians leave J the ZOO files in format suitable for extraction on VMS. The .LZH files areF produced and decoded by the LHARC utility, which is similar to ZOO butF does a better job of compression. LHARC files produced on VMS are leftD in suitable form for decompression on VMS; like ZOO files, they needI to be in STREAM_LF format for this to be done. In the Spring 1991 time, a E "high performance" compression was added to ZOO, so that it again has H better compression than LHARC. The Spring 2001 tapes contain executables for this new Zoo.   E 	All areas have ONE AAAREADME.TXT (and possibly many something.DOC or K something.1ST or something .MEM or something_else.TXT or *READ*.something). N This is so the AAAREADME.TXT's will be short enough to help you find a programN without being cluttered up with how to install or how to use the software.  IfN you are making up a submission for the next tape you can make it easier for us= to put the tape together if you will follow this convention.    @ 	Be sure and look through the tapes for all backup sets present.    ' 	Glenn C.
