Notes on the AMIGA VERSION

The Amiga version of SC 4.1, which I call "Dave's SCalc V1.0", is basically
the UseNet version of SC 4.1 with heavy Amiga enhancements.  I've tried to
keep it sane enough to still compile under UNIX or VMS, but I haven't
actually tried it.  The encryption isn't supported, since there's no 
standard Amiga encryption filter, and I haven't fixed some of the piping 
features to take advantage of Amiga pipes, though with the Amiga's 
filespace pipes, the special code used for UNIX isn't really necessary.

The original port of SC to the Amiga environment was done by Dave Wecker,
using ANSI console I/O at the DOS level.  This new version started with 
that curses-emulation code as a basis, but it's been greatly expanded.  It 
addresses the console.device directly for output, and gets input through 
Intuition.  It also gives you your choice of windowing modes, and has many 
of the more popular keyboard commands available via menus.  All of this new
code, in the spirit of the SC program, is released to the public domain.

SCalc can be run from either the CLI or the WorkBench.  From the CLI, it
accepts a optional windowing option and an optional file name.  From the
WorkBench, the DISPLAY tooltype selects the windowing mode.  The 
windowing options are as follows:

DISPLAY						CLI	WORKBENCH

HIRES Screen, 1 bitplane			-c	CUSTOM
HIRES|INTERLACE Screen, 1 bitplane		-i	INTERLACE
Resizable WorkBench Window			-w	WORKBENCH

The CUSTOM display is the default mode.

( Note: for AmiKit, the display was changed to WORKBENCH - JWV )

Notes on the Usenet VERSION

This is a much modified version of the public domain spread sheet sc,
posted a year or two ago by Mark Weiser as vc, originally by James Gosling.

Changes since my last version (3.1):

1) More portable external declarations
2) Range names
3) Encryption (Thanks to Bradley Williams)
4) @rnd rounding operator
5) 5.3 compatibility (%$#@% curses!)
6) @stddev standard deviation function
7) max, min changed to range functions (NOT COMPATIBLE WITH LAST RELEASE!)
8) Clean up and bug fixes
   Thanks to Larry Campbell for the xmalloc stuff, Eric Goldman, Carl
   Clawson, Narayan Mohanram, Greg Franks, Rick Daley and 
   Nick (lai@ucla) for bug reports and enhancements.

I had several requests for a modification that I don't personally
like.  Since Larry Campbell sent the mods, I compromised and added them
under the compilation flag "QUICK".  If you want to enter numeric
constants into cell locations by just typing the number without a
leading "=", set "QUICK" in the makefile.  The down side of the change
is you must always type ^U before you can enter a leading count
parameter for a command or before "0" to return to column 0.
Since many of the commands allow a leading count, I felt the change was
not a win.  I did not document the mod in the man page since I don't
use it.

I have modified the makefile to make it easy for you to call the
program what you want (I saw at least five different names in
correspondence and on the net).  Just change "name=sc" and "NAME=SC" to
"name=myfavoritename" and "NAME=MYFAVORITENAME" and try "make
myfavoritename".

Similarly, you can make the documentation with "make myfavoritename.man".
"make install" will make and install the code in EXDIR.  The
installation steps and documentation all key off of the name.  The
makefile even changes the name in the nroffable man page.  If you don't
have nroff, you will have to change sc.man yourself.

The code has been tested against a Vax running 4.2 and 4.3 and a National
ICM-3216 with system V.2 and V.3.  The ICM has a National Semi 32016.  Just
check the makefile for the system flags.   I have heard reports of lots
of other machines that work.  I have added ifdefs for system III and for
Berkeley 4.3.  If you have problems with lex.c, and don't care about arrow
keys, define SIMPLE (-DSIMPLE in the makefile).  SIMPLE causes the arrow
keys to not be used.
