 FLX, or FILEX, is used as a media format interchange program to move
 files among Files-11, DOS-11, and RT-11 structured volumes.
 
 FLX performs file transfers and format conversions from:
 
     o DOS-11 to Files-11 volumes
 
     o Files-11 to DOS-11 volumes
 
     o DOS-11 to DOS-11 volumes
 
     o Files-11 to Files-11 volumes
 
     o Files-11 to RT-11 volumes
 
     o RT-11 to RT-11 volumes
 
     o RT-11 to Files-11 volumes
 
 
 The general form of the FLX command line is:
 
     devicespec/switch=infile/switch,...,infilen/switch
 
 where
 
 devicespec is the device specification for the FLX output device.
 It takes the form : dev:[ufd]
 
 infilen are the input file specifications.
 
 switch is one of three types of FLX switches. Volume format, transfer
 mode, and control are the three types of switches.

2 VOLUMESWITCH
 
 FLX has three volume format switches that specify the format of the
 volume on which the file is stored. These switches are:
 
      /DO     Identifies the volume as a DOS-11 formatted volume
 
      /RS     Identifies the volume as a Files-11 formatted volume
 
      /RT     Identifies the volume as an RT-11 formatted volume
      
 Input volumes default to DOS-11 format and output volumes default
 to Files-11 format. You can change the default by entering /RS or/DO
 on a command line by itself.
 
 /RS sets the default for input volumes to Files-11 format and output
 to DOS-11 format.
 
 /DO sets the default for input volumes to DOS-11 format and output
 volumes to Files-11 format.
 
 For example, to specify the default transfer direction from Files-11
 to DOS-11, type:  
       
         FLX>/RS
 
 To specify the default transfer direction from DOS-11 to Files-11, 
 type: 
 
         FLX>/DO
 
 If /RT is specified on one side of the command line, the default 
 entry for the other side is /RS.
 
2 TRANSFERSWITCH
 
 FLX has three transfer mode switches, one for each type of file
 format. Format conversions can be in either direction, and are 
 between DOS-11 files and Files-11 files or between RT-11 files
 and Files-11 files. Specifying a transfer mode switch determines
 which format the output file will be in after the conversion of
 the file. These switches are:
 
      /FA:n[.]  The DOS-11 or RT-11 output file is to be formatted
                ASCII.
 
      /FB:n[.]  The DOS-11 or RT-11 output file is to be formatted
                binary.
 
      /IM:n[.]  The transfer is to be in image mode. Image mode forces
                fixed length records.
 
 If you specify n with any of the above switches, fixed length output
 records are generated. If n is specified when the output is not a 
 Files-11 file, n is ignored.
 
2 CONTROLSWITCH
 
 FLX control switches provide control functions useful during file 
 transfers. You can specify for example, the number of blocks to be 
 allocated to an output file or the UFD for an output file. These
 switches are:
 
      /BL:n[.]   Specifies the number of contiguous blocks in octal
                 or decimal to be allocated to the output file.
 
      /BS:n[.]   Specifies the block size in bytes for cassette tape
                 output.
 
      /CO        Specifies that the output file is to be contiguous.
 
      /DE        Deletes files from a DOS-11 DECtape or disk
 
      /DI        Causes a directory listing of cassettes or DOS 
                 volumes to be listed  in a specified output file.
                 If no output file is specified, the listing is
	         output on the user's terminal.
 
      /DNS:n     Specifies the density of a magnetic tape where
                 n can be 800, 1600 or 6250 bpi.
 
      /FC        Indicates that FORTRAN carriage control conventions
                 are to be used when using FORTRAN files.
 
      /ID        Identifies the current version of FLX.
 
      /LI        Same function as DI
 
      /NU:n[.]   Used with the /ZE and /RT switches to specify the
                 number of directory blocks in octal or decimal to
                 allocate when initializing an RT-11 disk or DECtape.
                 The maximum number of blocks is 37(8) or 31(10).
 
 
      /RW        Rewinds the magnetic tape before beginning the file
                 transfer.
 
      /SP        Specifies that the converted file is to be spooled by
                 the print spooler or queue manager.
 
      /UI        Specifies that the output file is to have the same 
                 UFD as the input file.
 
      /VE        Specifies that each record written to a cassette is
                 read and verified.
 
      /ZE        Initializes cassettes or DOS-11 volumes. Initializing
                 erases any files already on the device.
