1 CMPR
 Compresses or uncompresses sequential files.

 Format:

   CMPR file-spec[,...]

 Compressed files are binary data.  This means that the contents  are
 not readable.  DO NOT PRINT A COMPRESSED FILE.

 When you need the contents of a compressed file, use the /UNCOMPRESS
 qualifier to re-create the original file.
2 Parameter
 The name of the file to be compressed.  Several file  names  can  be
 given, separated by commas.  For each named file, CMPR will create a
 compressed file with the same name, but with "_Z"  appended  to  the
 file type.  For example, if you have two files called REPORT.RNO and
 REFERENCES.TXT, the command

     $ CMPR REPORT.RNO, REFERENCES.TXT

 will create two files called REPORT.RNO_Z and REFERENCES.TXT_Z .
2 /DELETE
 This qualifier causes CMPR to automatically delete each  input  file
 after  creating  the corresponding compressed or uncompressed output
 file.
2 /UNCOMPRESS
 This qualifier tells  CMPR  to  decompress  the  named  file(s)  and
 re-create the original version(s).
2 /OUTPUT=FILESPEC
 By default, CMPR creates an output file with a  name  based  on  the
 name  of  the  input  file.   This qualifier forces CMPR to use some
 other name.  If the FILESPEC is a directory path, all  output  files
 will  have  default  names, but they will be placed in the specified
 directory.

 Use /OUTPUT=TT:  to have the output sent  to  the  terminal.   NOTE:
 This  should  only  be  used  in  conjunction  with  the /UNCOMPRESS
 qualifier -- compressed files contain binary information which  will
 not  print  nicely  on  a  terminal  screen  (just like .EXE or .OBJ
 files).

 Examples:

    This command compress all FORTRAN files in the current  directory
    and   stores  the  compressed  files  in  a  subdirectory  called
    ARCHIVE.DIR .

       $ CMPR/OUTPUT=[.ARCHIVE] *.FOR

    This command decompresses a file called PHONELIST.TXTZ and prints
    the contents on the terminal:

       $ CMPR/UNCOMPRESS/OUTPUT=TT:  PHONELIST.TXTZ
2 Usage_notes
 CMPR is based on the COMPRESS program from  USENET.   It  creates  a
 compressed  file  for  each  file  named in the parameter list.  The
 compressed files require less disk space than  the  original  files.
 The  original  files  can  then  be  deleted.   When the data in the
 original files is needed, the original files can be re-created using
 the   /UNCOMPRESS   qualifier.    CMPR  preserves  RMS  file  format
 information, so that when a file is decompressed it  will  have  the
 same format as the original file.

 To view the contents of  a  compressed  file  without  creating  the
 decompressed  file,  use  the  qualifiers  /UNCOMPRESS/OUTPUT=TT:  .
 This will make CMPR send the information to the screen, just as TYPE
 does for ordinary files.

 CMPR only compresses sequential files; it cannot compress indexed or
 relative files (such as NOTES$NOTEBOOK.NOTE or MAIL.MAI).

 Compressing a file which is already compressed usually WASTES space.
 This is indicated by a negative compression percentage.
