added more.fs for people with old terminals.
WORDS and SEE now now respect the terminal size.
a lot of reordering in the Makefile, approaching the GNU standards.
factored NAME>STRING out of many words.
removed emitcounter (it was not used anyway).
SYSTEM now unpreps and repreps the terminal.
fixed byg in prims2x.fs.
added NEEDS, ?CSP, !CSP.
rewrote ALIAS?.

    1: You need gcc version 2.0 or later to compile gforth.
    3: First, type
    5: ./configure
    7: configure has the following useful parameters:
    8:   --prefix=PREFIX         install architecture-independent files in PREFIX
    9:                           [default: /usr/local]
   10:   --exec-prefix=PREFIX    install architecture-dependent files in PREFIX
   11:                           [default: same as prefix]
   12:   --enable-force-reg      Use explicit register declarations if they appear in
   13:                           the machine.h file. This can cause a good speedup,
   14:                           but also incorrect code with some gcc versions on
   15:                           some processors (default disabled).
   16:   --enable-direct-threaded      Force direct threading. This may not work on
   17:                                 some machines and may cause slowdown on others.
   18:                                 (default processor-dependent)
   19:   --enable-indirect-threaded    Force indirect threading. This can cause a
   20:                                 slowdown on some machines.
   21:                                 (default processor-dependent)
   22:   --with-debug     specifies option -g to compile with debug info (default)
   23:    --without-debug  omits the -g switch and creates smaller images on
   24:                     machines where strip has problems with gcc style
   25:                     debugging informations.
   26:   --help: tells you about other parameters.
   28: If you don't like the defaults for the installation directories, you
   29: should override them already during configure.  E.g., if you want to
   30: install in the /gnu hierarchy instead of in the default /usr/local
   31: hierarchy, say
   33: ./configure --prefix=/gnu
   35: Moreover, if your GCC is not called gcc (but, e.g., gcc-2.7.1), you
   36: should say so during configuration. E.g.:
   38: env CC=gcc-2.7.1 ./configure
   40: You can also pass additional options to gcc in this way, e.g., if you
   41: want to generate an a.out executable under Linux with gcc-2.7.0:
   43: env "CC=gcc -b i486-linuxaout -V 2.7.0" ./configure
   45: After, configuration, type
   47: make
   49: Now you can check whether your shiny new Forth system works. Say
   51: make test
   53: You can run some benchmarks with
   55: make bench
   57: and compare them with the results in Benchres and in the manual.
   59: If everything is all right, you may want to install gforth. Type
   61: make install
   63: You have to make an entry in the info directory file manually.
   65: For paper documentation, print (a Postscript file (300dpi
   66: fonts, i.e., it works, but does not produce best quality on better
   67: printers)), or say
   69: make gforth.dvi
   71: and print the resulting file gforth.dvi. You can also get the
   72: documentation in HTML format by typing
   74: make html
   76: If you prefer plain ASCII documentation, just concatenate the files
   77:* ('cat*' under Unix).
   79: 		Preloading installation-specific code
   81: If you want to have some installation-specific files loaded when
   82: Gforth starts (e.g., an assembler for your processor), put commands
   83: for loading them into /usr/local/share/gforth/site-forth/site-init.fs
   84: (if the commands work for all architectures) or
   85: /usr/local/lib/gforth/site-forth/site-init.fs (for
   86: architecture-specific commands);
   87: /usr/local/lib/gforth/site-forth/site-init.fs takes precedence if both
   88: files are present (unless you change the search path). The file names
   89: given above are the defaults; if you have changed the prefix, you have
   90: to replace "/usr/local" in these names with your prefix.
   92: By default, the installation procedure creates an empty
   93: /usr/local/share/gforth/site-forth/site-init.fs if there is no such
   94: file.
   96: If you change the site-init.fs file, you should run "make install"
   97: again for the changes to take effect (Actually, the part of "make
   98: install" starting with "rm" is sufficient).
  101: 		Multiple Versions and Deinstallation
  103: Several versions of Gforth can be installed and used at the same
  104: time. Version `foo' can be invoked with `gforth-foo'. We recommend to
  105: keep the old version for some time after a new one has been installed.
  107: You can deinstall this version of Gforth with 'make uninstall' and
  108: version foo with 'make uninstall VERSION=foo'. 'make uninstall' also
  109: tells you how to uninstall Gforth completely.
  112: 			A Possible Problem
  114: You need to read this only if you see a message like
  116: "gforth: Cannot load nonrelocatable image (compiled for address 0x1234) at address 0x5678
  117: The Gforth installer should look into the INSTALL file"
  119: Gforth supports both relocatable and fixed-address images. If you load
  120: normal Forth code and save the image, you get a fixed-address
  121: image. Producing a relocatable image is more difficult.
  123: Therefore, Gforth has only a relocatable image of the kernel
  124: (, which is powerful enough to load the rest of
  125: Gforth. However, loading the rest takes a noticable amount of time. To
  126: avoid this delay (which would occur on every startup), the
  127: installation procedure produces an image fixed at an address
  128: determined at the Gforth run that produced the image. This
  129: fixed-address image is loaded by default. On most OSs this works,
  130: because the first chunk of memory is always allocated at the same
  131: address. If the address changes, you get the message above.
  133: An image address change can be caused by a change of the gforth
  134: executable, or by a change (upgrade) of the OS; in these cases you
  135: just have to rebuild and reinstall the fixed address image with
  137: rm; make; make install
  139: If you get such a message with a different address in place of the
  140: 0x5678 each time you try to start gforth, you cannot use fixed-address
  141: images on your OS. In this case, send us a message so that we start
  142: searching for a comfortable solution to this problem. In the
  143: meantime, start gforth with
  145: gforth -i startup.fs
