The DOS files on the F disk constitute the F editor for PCs under DOS.

After performing the standard installation process of your toolset you will
find a directory called F at the same level as the directories TOOLS and
ITOOLS which contain most of the other tools. Having read this introduction
you may decide to copy files from this directory to the TOOLS and/or ITOOLS
directories. The structure within the directory F should be:

/F
 /TOOLS
  F.EXE            DOS executable file
  NECF.BAT         Batch file for calling F on NEC PC host
 /ITOOLS
  F.EXE            DOS exe to call F.BTL on the transputer board
  F.BTL            F bootable transputer program for any 32-bit transputer
  NECF.BAT         Batch file for calling F on transputer board on NEC PC
 /DATA
  READ.ME          This file
  FOLD.CMD         Specimen default command history file
  FOLD.STP         Startup file
  PCFOLD.ITM       ITERM file for PC/AT and compatibles
  PCFOLD.HLP       Keyboard help file for PC/AT and compatibles
  FTUTOR.OCC       An on-line tutorial on which you can try out F
  ASCII.ITM        A simple ITERM file in case you have non-standard terminal
  ASCII.HLP        Keyboard help file for simple ITERM
  BANSI.SYS        Screen driver with extended capability
  NECFOLD.ITM      ITERM file for NEC PC 9801
  NECFOLD.HLP      Keyboard help file for NEC PC 9801
  NECINI25.LIS     Special file for NEC
  TDS3KEYS.LD      Special file for NEC
  TDS3KEYS.TBL     Special file for NEC
  DOSKEYS.LD       Special file for NEC
  DOSKEYS.TBL      Special file for NEC

If you have installed the software on an NEC PC there are further instructions
in the delivery manual. The following paragraph does not apply on the NEC PC.

If you have not already installed a full ANSI screen driver such as BANSI.SYS
you will have to edit CONFIG.SYS to identify this driver and reboot. The F
editor will not work with the standard DOS ANSI.SYS which does not obey the
escape sequences for insert/delete line and clear from here to end of screen.
You may mave done this already to support other INMOS products.

Like all INMOS PC hosted products the F editor runs on a B004, B008+TRAM or
equivalent transputer system. The editor is supported by the INMOS server
ISERVER, and you may use any version of this server from the IMS D705B,
IMS S708B/C, IMS D700E or IMS D7205. Remember to set the environment variable
IBOARDSIZE to the transputer board memory size in bytes.

The environemt variable FTERM should be defined to be the full path
and name of the PCFOLD.ITM iterm file. This iterm file should also work
satisfactorily for IMS D705B, IMS D700E and IMS D7205 and so may also be
identified by the environment variable ITERM if so desired, but some key
allocations will no longer match the documentation of those toolsets.

Ensure that the correct version of ISERVER for your
transputer board is called. Only use a B008 ISERVER if you have installed a
B008 driver.

The iterm file PCFOLD.ITM points, in a section of F specific items to a
start up file. By default this is in the user's current directory. To avoid
the need to copy this to all directories in which editing is to be performed
this file should be identified by an appropriate absolute path and file name,
accessible from wherever the editor might be called. The startup file in turn
identifies the command history file FOLD.CMD in a similar manner and this
reference may also be made absolute if this file is to be shared.

The keyboard help file which is displayed when the Help key is pressed is
identified in one of two ways. Fistly the startup file is searched for a line
starting "helpfile". If this is present the file identified on this line is
used. If not, the name given by the FTERM environment variable is modified to
have the suffix ".HLP" instead of ".ITM" and this file is used.

You will need to decide whether to use one globally accessible FOLD.CMD
command history file, or to use a local one in each working directory.
This is determined by the name in the line starting "command" in the startup
file.

Having made these adjustments you may either include the F directory in
your DOS search path, or copy the file F.EXE to a directory that is already
on the path.

You may then call F from any directory by typing:

F filename1 filename2 ... filename9

which will read up to 9 files and leave you looking at the top level of the
first of these.

If you have not used an INMOS folding editor before, you are recommended to
work through the tutorial by typing:

COPY ftutor.occ saveftut.occ
F ftutor.occ
