1 FLXIBM

     The FLXIBM  utility  is  used  to  read/write  IBM  3741  formatted
     floppies.   The  dikettes  used  must  be formatted for IBM's basic
     dataset interchange format.

     The general FLXIBM command format obeys  the  standard  syntactical
     rules  for  RSX  utility  commands.  Six switches can be applied to
     FLXIBM command strings :

                           LI,FU,DE,RS,HE,IN

         GENERAL RESTRICTIONS

        (1) Wildcards are not allowed
        (2) Filenames are truncated to 8 characters if more typed in
        (3) Unit numbers are truncated to 2 chars if more typed in
2 /HE

         USAGE OF THE HE-SWITCH

     This switch is implemented to allow the display of this HELP - file
     with FLXIBM.  No file specifiers are allowed.

     VALID EXAMPLES:

            $ MCR FBM /HE
2 /IN

         USAGE OF THE IN-SWITCH

     This switch is implemented to allow you to reformat a floppy, which
     is  highly  fragmented because of many delete/write functions.  You
     must be careful in initializing a  FLOPPY,  because  disk  resident
     data  will  be  completely  destroyed.   After  the  initialization
     process the FLOPPY has the standard 3741 initial directory.

     However, the floppy is setup with a file "DATA", which occupies the
     whole floppy space.  In order to free this space you must issue the
     following command:

            $ MCR FBM DYU:DATA/DE

     which makes the FLOPPY now available for use.

     FORMAT:   $ MCR FBM DYUU:/IN

2 /LI

         USAGE OF THE LI-SWITCH

     This switch is needed to list information about the IBM-files on  a
     specified flexible disk.

     FORMAT:   $ MCR FBM DYUU:IBMFSP/LI

     where UU denotes the floppy unit and can be  omitted  for  unit  0,
     IBMFSP is a IBM filespecifier and can also be omitted

     VALID EXAMPLES :

            $ MCR FBM DY:/LI
            $ MCR FBM DY10:/LI
            $ MCR FBM DY05:DUMMY/LI

2 /FU

         USAGE OF THE FU-SWITCH

     This switch is used in the same  way  as  the  above  described  LI
     switch  only  with  the  difference that more information about the
     files on the IBM floppy is provided.  All  directory  segments  are
     printed  out (including sectors with deleted data mark), as well as
     BOE, EOE, EOD.

     FORMAT:   $ MCR FBM DYUU/FU

2 /DE

         USAGE OF THE DE-SWITCH

     With this switch you can delete a single specified IBM  file  on  a
     specified IBM floppy.

     FORMAT:   $ MCR FBM DYUU:RSXFSP/DE

     where UU denotes the floppy unit and can be  omitted  for  unit  0,
     RSXFSP  is  a RSX filespecifier specifying an IBM file which has to
     consist   of   a    filename    at    least;     everything    else
     (UIC,extension,version number) is ignored.

     VALID EXAMPLES :

            $ MCR FBM DY:[123,456]RUBBISH.IBM/DE has the same effect as
            $ MCR FBM DY:RUBBISH/DE

2 /RS

         USAGE OF THE RS-SWITCH

     This switch is used to specify a RSX file in a transfer  operation.
     Since there are two transfer directions two formats are valid :

            $ MCR FBM RSXFSP/RS=DYUU:IBMFSP for reading an IBM file and
            $ MCR FBM DYUU:IBMFSP=RSXFSP/RS for writing an IBM file

     where RSXFSP stands for an RSX filespecifier which can  be  omitted
     (in  this case SY:IBMFILE.DAT is default) and IBMFSP denotes an IBM
     file (only filename must be present).

     VALID EXAMPLES :

            $ MCR FBM SY:[123,456]DESTINATION.DST/RS=DY1:IBMSOURCE
            $ MCR FBM DY:IBMDEST=RSXFILE/RS
