320K Version of AnalytiCalc (Document Supplement)

The 320K version of AnalytiCalc differs from the normal 256K version
in two ways: it is not overlaid, and it supports logical names.

	The 256K version uses overlays from disk to save memory,
and consequently a spreadsheet that uses many special functions
that are in different overlays (e.g., large amounts of matrix
math plus large amounts of date conversions) will be slowed.
The 320K version is non overlain and there is no penalty for
any function mix.

	The 320K version also has a symbol table and allows you
to define symbolic names of up to 16 characters length, containing
letters or numbers, and use them inside equations.

	To define a symbolic name, use the command

TE {SYMBOLICNAME=Vn

where Vn is a cell name (like A5, R17, AB122, or the like), and
"SYMBOLICNAME" is the name you wish to define. The name is now
associated with the CONTENTS OF the cell named (as Vn). When you
use the construct {SYMBOLICNAME in an equation, the contents of
the cell associated with that name replace the name prior to
evaluation. Any contents may be used, though the total resulting
string must not grow to over 109 characters. Recursive substitutions
are permitted to a depth of 20, so name definitions may use other
name definitions.

	To remove a name definition, use the command

TE {SYMBOLICNAME=0

You should remove definitions explicitly since they are not automatically
removed by adding new definitions.

Up to 301 names may be defined in the sheet. Note that scratch
cells A0 through approximately BK0 may be used to hold definitions
if desired.


	To store cell definitions for later use, the special command
must be used as follows to save them:

TE {*=

This will cause AnalytiCalc to ask for an Output file.
You reply with a filename to store (or show) the definitions.
The program will then dump all known symbol definitions in the
same format needed to do the definitions of the names. If a disk
file is specified, it can be read in via the @file command
so the symbols may be redefined to a later AnalytiCalc run.

Storing definitions on CON: can give a quick look at them
interactively, but usually it is better to print the definitions
(which can be done by giving LPT1: (or your printer's real name
if that's not it) as the output file name.

	This facility can save considerable formula typing
time. Where you have a very large formula to be duplicated
many times, if it can be specified relocatably, a reference to
a short name (or a cell, since {name and {cell function the
same) can save storage and allow you to get by with smaller
disk work files. The 256K AnalytiCalc has the {cell logic
to do substitutions, but the names must be cell names. Only
the larger one has room for the name dictionary.

EXAMPLE RUN:

L D0			;  go to phantom cell D0
ET SUM[A1:A4]		;  fill in a macro definition as text
TE {SALES=D0		;  define "sales" as this sum
M2			;  set automatic motion down
L A1			;  go to A1 
E 2.3			;  enter some junk data just to show this
E 4.86
E 1.2647
E 8.3454
EV {SALES		;  Enter sales value as a numeric.

	;  the cell will display the sum of A1 thru A4.

An example position independent formula might be:

SUM[ P#0#-5:P#0#-1]

which means the sum of the cells from 5 above the current physical
cell to 1 above the physical cell. This form if used in a name
will work wherever it is used, regardless of location.
