5CD-ROM, Utilities, Read a High Sierra (ISO-9660) DiskHCD-ROM access routines for VAX/VMS 29 November 1989I------------------------------------------------------------------------ 1The programs in this directory were developed by:$ United States Geological Survey Branch of Astro Geology 2255 N. Gemini Drive Flagstaff, AZ 86001Gfor the purpose of reading the CD-ROMs produced in the ISO 9660 format Astandard (or in the "High Sierra" standard) on a VAX/VMS computer@system. Permission has been obtained from the U.S.G.S. to placeCthese programs on the VAX SIG tape. The programs are in the public?domain, and are provided for use with the following disclaimer:6 "Although these programs have been used by the United2 States Geological Survey no warranty expressed or3 implied is made by the USGS as to the accuracy and0 functioning of the programs and related program3 materials, and no responsibility is assumed by the USGS in connection therewith."KThe programs were produced to read the Voyager CD-ROMs to be read on VAXes.M* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *HThe programs allow a file on an ISO 9660 format CD-ROM to be opened, andG512 byte blocks of data read from the file relative to the beginning of the file.JThe original files from the U.S.G.S., as downloaded from the SPAN network,(are CDVMS2.TXT;2 and CDVMS3.TXT;1.HAll other files were extracted from these .TXT files, with the exceptionGof the B2B.MAR program which was not in the original files and was sentCin hardcopy by U.S.G.S. and rekeyed. All programs work with eitherFISO 9660 or "High Sierra" format CD-ROMs. Main programs provided are:1 CDDIR Do a directory listing of a CD-ROM: CDCOPY Copy a file from a CD-ROM to another device6 CDTYPE Type the contents of a file on a CD-ROMFThe original version of CDDIR (CDDIR.ORIGINAL) was modified at ICDD toEdefault to a 3 character file extension since the LENOSP routine usedGin CDDIR was missing. The original version of CDOPEN (CDOPEN.ORIGINAL)Ewas modified at ICDD to correctly find and report the contents of theIextended attribute record (XAR). The following subroutines are provided:C CDOPEN Find and open a CD-ROM file, returning the offset of$ the start of the fileD CDREAD Read 512 byte block records relative to the beginning of the file" CDCLOSE Close a CD-ROM fileC CDSTAND Determine if the CD-ROM is ISO 9660 or "High Sierra"B CDATT Obtain extended attribute record (XAR); CDATT is an( ENTRY point within CDOPEN B2B Move bytes7All executables were produced on a VAX/VMS V5.2 system.M* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *?These routines have been made available to the VAX SIG tape by: Mark A.

Holomany and the JCPDS-International Centre for Diffraction Data(also known as ICDD).LThese routines were described in the session "CDROM Use on a VAX/VMS System"N(VA076) given at the Fall 1989 DECUS Symposium in Anaheim by Mark A. Holomany.The session was taped.KFeel free to contact me at the above number should you have any comments onCthese programs, or if you have any questions on CD-ROMs in general.[End of AAAREADME.TXT]
