1 FLX
 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
 
 devicespec is the specification for the FLX output device. DEV:[UFD]
 
 infilen are the input file specifications.

 TRANFERSWITCH, AID FLX CONTROLSWITCH.
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 to Files-11 format and output to DOS-11.
 
 /DO sets the default for input to DOS-11 format and output to Files-11.
 
 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
 
      /BL:n[.]   Specifies the number of contiguous blocks in octal or decimal.
      /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.
      /DNS:n     Specifies the density of a magnetic tape where n=800/1600/6250
      /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 init-
                 ializing an RT-11 disk or DECtape. Maximum is 37(8)/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.
