=               VAX SIG Spring 1989 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. A 	   Neither your librarian, DECUS, nor DEC has detailed knowledge A 	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 librarian makes 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 508-480-3418. Please> 	ask that Marilyn Rosenberg, Betty Cadieux, and Glenn EverhartB 	(your librarian) be informed of the problems. (If possible, leave 	a phone number.) ? 	   You can reach your librarian (Glenn Everhart) on ARPAnet at  	the network address# 		Everhart%Arisia.decnet@CRD.GE.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.   B     The tapes this time are combined VAX SIG and L&T SIG tapes, to> reduce duplications between the two collections. The VAXLT_89A; directory is the master index directory for the entire set.   H     The top level description summary to the Spring '89 VAX/LT SIG tapesC is contained in ABSTRACT.TXT and VAXLT89ATPE.DOC in this directory. ; For a longer description see AAAREADME.*,  the concatenated E AAAREADME.TXT files from the respective submissions.  AAAREADME.TXT's I back through the Fall 1981 tape are in a sub-directory [.OLD_AAAREADME].    ? 	The tapes are in VMS Backup format in six save-sets - one each I for [VAXLT_89A...], [VAX89A1...], [VAX89A2...], [VAX89A3...], [LT89A...], J and [DECUSLIB...]. The first is the index saveset, comprising around 11000K blocks. The others are the DECUS library catalog in machine readable format G ([DECUSLIB...]) and the four parts of the VAX/L&T collection for Spring D 1989. These are each a bit under 60K blocks long, and are so divided( that each will fit on a 1600BPI magtaoe.B 	Distribution requires two TK50 cartridges. The first will contain
 the savesets: ) 	VAXLT_89A, DECUSLIB, LT89A, and  VAX89A1 ! The second will contain savesets:  	VAX89A2 and VAX89A3.   @ 	The entire collection fits (with large block sizes, and barely)I on a single reel of tape at 6250 BPI density. Because of the large volume F of excellent submissions, it was impossible to fit the collection onto smaller media.? 	Very few files are compressed this time, due to the difficulty H such compression created. However, the LZDCM and LZCMP files are locatedE with their sources in the [VAX000.TOOLS...] directory. This directory @ also contains VMS versions of the ARC and ZOO archiving programsE (compatible with their PC counterparts), and TAR format reader/writer F programs, so that all programs needed to decompose compressed programsI are present. These require no privilege to run, and work fine on VMS 4.x. D They are believed to work on VMS 5.x also, but some recompilation orG relinking could be required. Any files of type .ARC or .ZOO can be read E by ARC.EXE or ZOO.EXE respectively. The commands ARC -h or ZOO h will B type built-in help messages for those programs (defined as foreign
 commands).C 	Wherever you find a file of type .*_LZW (usually THIS_DIR.BCK_LZW) G it is compressed with LZCMP. Decompress it with LZDCM by a command like + $ lzdcm:==${some directory and device}LZDCM % $ LZDCM this_dir.BCK_LZW this_dir.BCK ? 	The result will be a decompressed file, generally a VMS Backup J saveset. Use Backup to pull this apart to original files. Some compression3 was necessary to make the 3 tape set fit on a TK50. * 	LZDCM.EXE may be found in [VAX000.TOOLS].  C 	You will run accross .ARC files on some directories.  For those of A you not familiar with ARC it is an excellent file compression and D archiving program that is widely used in the microcomputer world forB distributing programs via floppy and bulletin boards.  You can useI [VAX000.TOOLS]VMSSWEEP (or ARC in the same directory) to read these files 	 on a VAX.   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.  B 	Because the index preparation was somewhat delayed this time, theH tapes do not have an index at this point. A version of the index will beG released later. As partial compensation, AAAREADME files from fall 1981 E on have been included this time. Using the SEARCH utility on them is  1 frequently effective in locating software needed.   E 	This tape was put together from submissions at the Spring 1989 DECUS  Symposium, Atlanta, Georgia, by      	Glenn C.
