LZW is a great compression\/packaging utility written by Randy Medd when he was with Telamon. The LZW algorithm, originally protected by a Unisys patent which expired in 2003, is now in the public domain, so everyone may use it freely.<\/P><\/p>\n
LZW provides a convenient method of packaging MPE files while retaining their file system characteristics. LZW compression is highly efficent, and can provide up to 90% reduction in storage requirements in some instances. Here is an example of how to use LZW to upload\/unpack a file<\/A>. <\/p>\n You may download a version of LZW here:<\/p>\n lzw.wrq<\/A>, WRQ labels-format NMPRG<\/li>\n \t \t \t lzw.raw<\/A>, raw binary file of NMPRG (see notes below)<\/li>\n \t <\/UL><\/p>\n For WRQ Reflection users, we recommend using the WRQ labels-format NMPRG.<\/p>\n This assumes you’ve downloaded the raw MPE\/iX or MPE V version of LZW to a local file called LZW.RAW (or LZWCM.RAW) on a PC or Mac. You may use one of the following two methods to upload the file to your HP 3000:<\/p>\n or, on MPE V:<\/p>\n <\/LI><\/p>\n or, on MPE V:<\/p>\n Upload the LZW.RAW file with the following commands:<\/p>\n or, on MPE V:<\/p>\n NOTE!<\/b> the "rec=256" is important! Without it, Reflection and\/or PCLINK may not upload the file correctly!<\/LI> LZW is a great compression\/packaging utility written by Randy Medd when he was with Telamon.

\nNotes on uploading the raw NMPRG version of LZW to MPE:<\/h4>\n
\n
\nStart an FTP session (perhaps: click on <START>, select <RUN>, and then enter "FTP", connect to your HP 3000 and logon). Use the following FTP put command:<\/p>\n\r binary\r put LZW.RAW LZW.PUB;rec=128,1,f,binary;code=NMPRG\r<\/pre>\n
\r binary\r put LZWCM.RAW LZW.PUB;rec=128,1,f,binary;code=PROG\r<\/pre>\n
\nConnect to your HP 3000 and logon. Then issue the following MPE command:<\/p>\n\r :file lzw.pub;rec=128,1,f,binary;code=NMPRG\r<\/pre>\n
\r :file lzw.pub;rec=128,1,f,binary;code=PROG\r<\/pre>\n
\r <ALT Y> (i.e., enter Reflection Command Line mode)\r s lzw.raw to *lzw.pub binary rec=256<\/b>\r<\/pre>\n
\r <ALT Y> (i.e., enter Reflection Command Line mode)\r s lzwcm.raw to *lzw.pub binary rec=256<\/b>\r<\/pre>\n
