PREFACE

Some people may seem undismayed by the aforementioned statement, considering that they have prior Knowledge of what is an "Electronic Spreadsheet Calculator’ (ESC) and that they know how to use it.

However, for the rest of the people who can't or don't yet appreciate the significant meaning conveyed by this colloquial expression, it is for them that this presentation is primarily intended.

My purpose herein will be to demonstrate that for the Timex/Sinclair family of computers there are ESCs capable of doing the two main things that an ESC was developed to do: 1.) to handle "what-if calculations electronically and 2.) to serve as a

general framework with which to build "models" for the purpose of continually summarising, reporting, and analyzing, in matrix form, any financial, accounting, mathematical, engineering, and scientific manipulation of

numerical data. And that the ESCs available for the T/S can be acquired for a fraction of the cost (and still carry as much “punch") as do the more sophisticated ESC versions for the higher priced computers.

| will use an ESC that is for sale by my own company to illustrate the preceding facts to the experienced as well as the inexperienced user in the audience. Literature about this ESC is readily available. Though, it is hoped that the distribution of such literature will only be deemed academic in semblance compared to the illustration of this ESC as our main example throughout this presentation.

PART |

In our first step toward demystifying what is an ESC and what its applications are | would like to begin by showing you what my ESC looks like from the start (See Fig. 1)

featuring an electronic

spreadsheet for the TIMEX/sinclair line of computers.

“wa +i

(fig. 1)

As you can see it is basically a grid composed of columns (A-O) and rows (1-30); where each intersection (column/row) meets it is a place for holding some sort of data(é a label, value, or formul ind these data comp: ents are referred to as "cells

The concept of an ESC is fairly new. The first ESC was introduced in 1978 by a student at The Harvard Business School by the name of Dan Bricklin. Mr. Bricklin's idea was that a spreadsheet provided a “better way to perform endless recaiculations of balance sheets, income statements, and forecasts required whenever a single assumption changed.” Reportedly, he modeled his first microcomputer- based spreadsheet program to "an electronic black-board and electronic chalk.” His original work had 5 columns and 20 rows. Later on Mr. Bricklin teamed up with Robert Frankston who enhanced this first ESC by increasing the number of cells and developed some "user-friendly" features and packed

the results into a 20K program for the Apple microcomputer. To make a long story short, this original invention was later named VISICALC and it is no secret that this software package went to become one of the most successful selling programs in the years prior to another popular integrated software tool called Lotus 1-2-3.

My company’s ESC for the T/S is called ZX-CALX (or T/S CALC 2000 for the T/S 2068). It was primarily designed after the VISICALC program. Not exactly as VISICALC, but similar in function, it can handle just about any procedure than the higher priced version.

My first task is to demonstrate how my program handles "what-if", contingency calculations like the higher priced ESCs do. Itis primarily with "what- if* calculations that a spreadsheet proves its most salient advantage and versatility versus the vertical- Statically-fixed formatted programs which offer a limited method for storing, displaying and manipulating numerical data. Also ZX-CALC has the ability to use its resources for producing any number of various display "models" that the latter programs do not have.

"What -if" calculations can be understood to occur in two set of

circumstances. First a cell may contain data in the form of a formula such as: A01+B01 assigned to C01. By this | mean that the cell C01 contains the formula A01+B01 continually, until the formula is changed or deleted from the program and that when you use the automatic-calculate option of the ESC the result of said formula will always appear in cell C01 and that the result will only vary if the

values in cells AO1 and BO1 should happen to change. Second, the program may assign the formula A01+B01 to cell CO1, but do so by entering this formula in the form of an equation each time the final resuk has to appear. That is, in the first case the formula is calculated but it is also hidden and saved for later use-by the program; whereas, in the second case no formula is hidden and saved by the program but it is allowed to be used and reused by manually entering it everytime the result is to appear in the designated cell (which in this case is cell C01). What is important to note from either "what-if method

of calculation is that the final

result of a calculation can be changed by simply recalculating the result-cell with the program as the data varies within the given formula. This ability to handle recalculations is what makes ESCs so unique in handling and displaying numerical data. Without this capacity to do recalculations there

.and dreams of home.

would be no other method than "backtracking" and using an eraser to change the intermediate and final results and later run through the entire calculation mode that was Originally used to arrive again at the new intermediate and final total results of a given matrix of numbers.

With respect to ZX-CALLC it is the second set of conditions that apply regarding how “what-if recalculations are done by it. That is, this program does not hide and save formulas in cells; it requires | that an equation be entered manually each time you wish to recalculate the data in the ESC. There are six reasons why ZX-CALC has this mode of "what-if" recalculation. First, it has to do with speed. It approximately takes 33 minutes to automatically recalculate the entire ESC. This is alright if there are numerous formulas scattered throughout the entire ESC, but in the case of just a few calculations it is preferable to use an equation that can generate actual results (e.g., sub-totals, totals, etc.,) within a matter of a few minutes instead of waiting a half-hour each time the ESC is recalculated. Second, there is usually (as in the case of another ESC known as VUCALC) a limit as to the number of formulas that can be included in an ESC. With ZX-CALC there are no limits to the number of

IMELINE

formulas that may be entered into the spreadsheet, since an equation is used to reenter the formula into

a given cell each time the spreadsheet is manually instead of automatically recalculated. Third, ZX-CALC is an applications program and how it is applied presents a more flexible and dynamic style than a program that requires that cell addresses be included within a given cell and hidden and saved within same for further recalculation. That is, you can use and enjoy using it more so than if the “shoe was on the other foot." Fourth, though the program code to allow my ESC to operate in the

first “what-if mode of hiding and saving formulae was written it was a matter of priority in calculation features included within the program that determined its fate primarily as a manually recalculatable ESC. For example, ZX- CALC includes a SUM function that allows one or more columns/rows to be added together to obtain subtotals, cumulative totals and final totals. Also my ESC includes a "replication" feature that allows cell data to be loaded or calculated according to one or more entire column/row, simultaneously, depending up to what cell address is "absolutely" or "relatively" specified in a given equation to copy a given calculation or data. Both of these two features were esteemed to be more important to

le Baa

calculation and recalculation procedures than including the first "what-if mode within the program. So the fact that ZX-CALC doesn't reference, hide and save formulae within a cell was a matter of trade- off between what comes first: versatility and speed versus simple "good looks.” Fifth, there just wasn't enough room in RAM to add the first type of “what-if” mode

into the program. But in short it wasn't necessary and it would have created (as | have already proven) certain disadvantages if it had been included. Finally, even though you are required to recalculate manually the spreadsheet there are no serious defaults in doing so, since the program is the one still responsible for handling the actual operational and mechanical contro! of a given equation whenever you attempt to recalculate the data in the spreadsheet. Therefore, the computer (not you) is what determines the final outcome of calculations performed with my ESC on a manual basis.

PU G N E w Ss w by Walt Gaby

THE OCTOBER 18 MEETING, WHICH WAS VIDEO-TAPED(!), WAS WELL-ATTENDED. THERE WERE MANY ITEMS OF INTEREST DISCUSSED.

JACK DOHANY REPORTED ON SEVERAL MATTERS. HE HAS JUST ABOUT COM- PLETED A MUCH-ENHANCED M/SCRIPT, VERSION 6. (SEE SEP/OCT ISSUE OF

I GNS AZINE, PAGE 18, FOR A COMPLETE REPORT ON IT.)

JACK ALSO INDICATED THAT HE WOULD RECOMMEND THE LARKEN DISK SYSTEM INTERFACE FOR THE 2068 AS THE BEST CHOICE. PAT MORRISSEY POINTED OUT THAT THE BEST DRIVES ARE THOSE MADE BY MITSUBISHI (3.5 INCH). FINALLY, HALTED ELECTRONICS IS A GOOD PLACE TO ACQUIRE CASES FOR THE DRIVES.

REX LUNDGREN GAVE A BRIEF REPORT

ON HIS CURRENT PROJECT, A BOARD WHICH SERVES AS A CENTRONICS/PARAL\, LEL-TO-SERIAL INTERFACE.

RITA TOTH SUGGESTED THAT, AS WE

HAD BEEN DOING IN THE CASE OF THE NEVADA PRISONER PROGRAM, WE NOW BEGIN TO HELP THE JUVENILE DIVISION IN SAN FRANCISCO.

WALT GABY (that's me) REPORTED ON HIS PLEASURE WITH HIS LATEST HARD- WARE ACQUISITION...THE PANASONIC P1091i PRINTER.

PANASONIC PRINTER CAN DO wit EASE 1S PRINT MANY CHARAC- TERS ON A LINE AND MANY LINES A STANDARD PAGE EXAMPLE, I DO MANY DOCUMENTS WITH 120 C

AND 140 LINES PER PAGE.

ALL READERS WILL NOTE THAT WE HAVE A NEV NEWSLETTER EDITOR. AS NORM LERPELDT INDICATED IB THE LAST ISSUE, BOTH WORK AUD PERSOMAL OBLIGATIONS LEFT HIM WITH LITTLE OR WO TIME FOR THE TASK OF EDITING.

It is true you get a complete \_ verson, but the new manuals are now — printed with four pages compressed into one 81/72 X 11 sheet of paper.

It seems that A+ isn’t producing the quality/care type aditude that

is need for this type of hobby.

Whew! Finally finished. What a job. I quess I forgot to say earlier that I was compiling this TIMEX/sinclair oriented magazine to honor others before me by actually doing everything by hand so to speak. The only computer I used is my QL and Quill for the text. Everything else was strickly cut and paste. Yes, the typewriter was out too. Hopefully I won’t have to repeat this for the December issue, (hear that Norm?>. Anyway, the Desk Top Publishing program should be at my door any day now.

Many of you aready know that Sunset Electronics is no longer selling Sinclair QL products. The Frisco bay area isn't lost yet. Thru Johns help, my wife and Ii have started a small company titled the QL CONNECTION, where we will be giving full support to the 68000 based machine in both hardware and software. Send for our catalog to:
