IMELINE?

BY ALBERT F. RODRIGUEZ--PART II

"An Electronic Spreadsheet: Function And Application"

PART I!

In this section of the paper | would like to focus on the valuable aspect of an ESC as a "model" builder using worksheets and templates to define and create a wide variety of frameworks with which a user may rely on repeatedly to record and report data on more than one occasion in the same identical manner.

To help us understand exactly what a "model" is | have chosen a particular accounting model package (sold by my own company) that makes use of the entire ESC Zx- CALC. The model is actually a supplementary application of ZX- CALC that serves to construct a financial picture of a relatively small enterprise (such as a sole proprietorship) for the purpose of analyzing or forecasting its financial performance. The name of this accounting model is called R.F.R.G. -- which stands for Ready Financial Report Generator.

This model allows the generation of 10 different financial- status reports about a company's past business history on a 6-12 month basis.

What the content of this text is concerned with is a layman's

explanation of what the

terminology of the model means and what the model does. This will ease the process of summarizing and recording the essential numerical values next to each subcategory of each of the ten categories comprising this accounting model package. In turn, you can use the program to perform your calculations in order to fill in the necessary bianks.

After the model has been entered into RAM then you fill in the appropriate blanks next to each template (i.e., Seti, Page-1). Each subsequent worksheet is Page-2 of the current Set with the next worksheet being Page-1 of the next higher-numbered Set then Page-2 of this Set. . ., and so on.

Within worksheets 1, 2, 3, and 4 we have the iotal picture that would generate a complete "cash flow" statement. This statement essentially reports the amount of money available, invested, how it was invested, and how much of itis left either in your pockets or left in a bank account. In worksheet 1 we have 2 subcategories under cash flow, which are "cash" and "cash receipts." Cash is the actual amount of capital you initially decided to invest in your business. Interest is the revenue earned on cash invested in some kind of demand deposit: checking, savings, and certificate-of-deposit

EDITOR'S NOTE:

ELECTRONIC SPREADSHEET PART II

Rodriguez will be giving this

lecture at the 1988 Florida Spring TIMEX/sinclair Fest. This

is a two part series

article featuring an electronic

spreadsheet for the TIMEX/sinclair line of computers.

accounts. "Cash Beginning" is the sum of both cash and interest. That is, it is the money used to runa company's total operations. Cash receipts are monies loaned, owed to and paid into a company by creditors, clients, or stockholders

of the company, respectively. Cash receipts are monies that when they are available to and are used by the company they normally are applied toward some purchase or amortization of some debt that the company incurred due to its regular operations. In worksheet 2 we list the "operating expenses" of a company. Here we list the overall administrative and selling expenditures of a company, including the interest service charge a company must pay if it borrowed money at a specified rate of interest. (Remember, during the preparation of your financial

reports you must set a definite, limited period of time during which these figures are compiled and recorded, therein). In worksheet 3 you report the depreciation of all fixed assets preferably using the straight-line method. With this method take the cost of a given product-good, subtract its residual value (e.g., about 35% of original cost) and devide by the number of life-years you believe the given product will last. In worksheet 4 you report total capital appropriations in order to obtain

the sum of a company's financial burden. You then subtract cash- beginning from total disbursements to obtain "cash ending," which is the money a company has on hand, usually in the bank or are funds

that it must borrow to meet

current expenses.

In worksheet 5 we have two reports. One is an "income statement". This report lists total sales and cost-of-goods-sold and subtracts them both to obtain gross profit and then subtracts gross profit from operating expenses to obtain total net income fora specified period of time. Next is the most essential report of them all which is a "balance statement" that reports a company's total assets compared to its total liabilities and stockholder's equity. By following each individual sub- category listed therein and referring to each preceding worksheet you will be able to record the proper figures needed to obtain a balance of assets-to- liabilities/equity. Worksheet 6 is simply the continuation and final segment of the "balance statement" report.

Worksheet 7 is a display of various important financial ratios that serve as a quick guide to making current decisions and investment forecasts about a

company's operations. In case you are unfamiliar with some of the terms used in this worksheet this is what they mean: (a full explanation of all labels used within the accounting model are in an Appendix enclosed with the package), Crt Rto, = current ratio; it is obtained by dividing current assets/current liabilities, Quk Rto. = quick ratio; itis obtained by dividing current equity/current liabilities. However, both ratios must be stated in relation to the number 1 (i.e. if current assets are $90,000.00 and current liabilities are $35,000.00 then the current

ratio should be displayed as 2.57:1).

Equity is defined to mean the total capital stock plus the retained earnings of a company within a

company's fixed assets as well as any deferred income tax taxes and withholdings of employee's salaries and wages and the sale of capital stock in the company. Since this accounting model is designed mainly for a sole proprietorship

like my company is, | felt that it

was not necessary to include these subcategories within this final statement. If necessary, however, any user may expand worksheets 9 and 10 to include these other 4 sub- categories if they indeed do apply.

from ’pachine code’ to ‘microcode’. Understanding the principles of sicrcode should enable us to write faster aachine code prograes.

Philip also commented on ‘Super Optiaizer’, an approxiaately 300 line long 68000 Asseably progras which finds the shortest and fastest 68000 progras to iapfement a given algorithe.

OLDIES BUT GOODIES! REMEMBER THESE THREE?

TURTLE GRAPHICS by Timothy Swenson

One of the most overlooked and unused capabilities of the QL is Turtle Graphics. Turtle Graphics is the basis of the language LOGO. Years ago LOGO was seen as the perfect language to start young children on. The heart of the language was the movement of a turtle cursor around the screen leaving a trail behind it. With simple loops one could get the

turtle to draw a box sor —2 five-point star.

Considering the past popularity of LOGO, I have yet to see any mention of Turtle Graphics on any QL related publication. It’s as if QL users

are too advanced to use such simple commands.

I personaly think that using the already present Turtle Graphic commands, a workable LOGO can be implimented on the QL. Procedures can be used to add keywords to the language. Remember procedures can be called at the immediate level by entering their name.

Not knowing LOGO it would be hard for me to try this implementation myself, although if someone is willing to lend me a book on LOGO I’11 give it a try. I can still see using a LOGO type language to help children start programming.

Now it’s time for me to get off of my soapbox and spend some time explaining Turtle Graphics.

Turtle Graphics, as it was originaly concieved, can be pictured as a little robot (turtle) running around on the floor with a pen attached to it.

The turtle can move forward, turn, lift the pen, and drop the pen (write). Now consider the

screen as the floor and a dot as the turtle. The commands that get the

QL Connection.... 344

turtle to do things are quite simpe: PENDOWN and PENUP enable and disable the drawing of lines. MOVE tells the turtle to move W units forward. TURN turns the turtle N degrees to the left. A negative WN would turn it to the right. Both MOVE and TURN are relative. This means that they remeber the last place the turtle was and do the command from there.

TURNTO makes the turtle turn to a specific heading no matter what the last heading was. To move the turtle to a specific place use POINT. This sets the point and moves the turtle to that point. Turtle Graphics are based on the QL graphics systen. Any graphic command affects the turtle. If you drew an ARC and then told the turtle to MOVE 5, the turtle would start at the end of the ARC.

This means that FILL may be used with turtle graphics. But be aware that the results may be a bit unexpected.

At the end of this article is a short program that demonstrates a use of Turtle Graphics. The program asks for a number of sides for a figure. The figure with 5 sides comes out to look like a 5-pointed star. All numbers entered must be odd. Give the programa try. Also try adding FILL statements and see what happens.

I hope I didn’t bore anyone with my ramblings.
