┬ASIC├ALC IS AN ELECTRONIC SPREADSHEET PROGRAM WRITTEN IN ┬ASIC 8.0 FOR HOME OR SMALL BUSINESS USE. ╔T IS LOOSELY BASED ON A ├64 BASIC SPREADSHEET PUBLISHED IN ╥╒╬ ═AGAZINE BY ╘RENT ┬USCH, BUT HAS BEEN HEAVILY MODIFIED AND ENHANCED. ┼VERYTHING FROM BALANCING A CHECKBOOK TO COMPLEX INVESTMENT ANALYSIS CAN BE DONE WITH A SPREADSHEET. ┬ESIDES CALCULATING DATA, IT CAN BE USED TO REPRESENT THAT DATA AS A BAR, PIE OR LINE GRAPH. ╔T CAN ALSO SAVE THE SCREEN TO DISK AS A BRUSH OR PAGE FOR USE WITHIN ┬ASIC╨AINT OR ┬ASIC╫RITE, OR PRINT THE SCREEN TO YOUR PRINTER. ╬O MATTER WHAT YOUR NEEDS, ┬ASIC├ALC WILL BE A VALUABLE ADDITION TO YOUR PROGRAM LIBRARY.
╘HIS DOCUMENT WILL TAKE YOU STEP BY STEP THROUGH THE FEATURES OF ┬ASIC├ALC. ╠ET US ╥╒╬ THE PROGRAM AND EXAMINE THE DISPLAY. ╠OAD AND RUN THE PROGRAM FROM THE ╫ORKBENCH OR DIRECTLY FROM THE KEYBOARD. (┬ASIC 8 OR THE ┬ASIC 8 ╥UN╘IME LIBRARY MUST BE INSTALLED IN MEMORY.) ┬ASIC├ALC WILL DEFAULT FROM WHATEVER DRIVE YOU LOAD IT FROM. ╔T STARTS OFF WITH A BLACK SCREEN WITH THE COMMENT "╔NITIALIZING ╓ARIABLES" DISPLAYED. ╘HERE WILL BE A SHORT PAUSE, THEN THE TITLE SCREEN APPEARS. ╘HE PROGRAM WILL KNOW HOW MUCH RAM IS PRESENT BOTH IN THE SYSTEM AND THE VIDEO DISPLAY MEMORY AREA. ┬ASIC├ALC WILL RUN ON A MINIMAL ├128, MEANING THE NORMAL 128 ╦ OF RAM AND 16 ╦ OF ╓─├ RAM. ╔F YOU HAVE A 1700 OR 1750 RAM CARTRIDGE, OR YOUR ├128 HAS 64╦ OF VIDEO RAM (AS THE ├128─ HAS) THE PROGRAM WILL RUN SMOOTHER BECAUSE MORE ITEMS WILL BE AVAILABLE FROM MEMORY.
╧NCE THE PROGRAM DISPLAYS THE TITLE SCREEN IT WILL BEGIN TO LOAD ITS FONTS, MENUS, AND HELP SCREENS. ╘HIS WILL TAKE ONLY A FEW SECONDS. ╫HEN IT IS COMPLETE THE WORDS ┬┴╙╔├├┴╠├ WILL BEGIN TO SCROLL AND MAKE A SOUND. ╔T WILL CONTINUE TO SCROLL UNTIL YOU PRESS A KEY. ╧NCE A KEY HAS BEEN PRESSED THE PROGRAM STARTS.
╘HE FLASHING ARROW AT THE TOP LEFT OF THE SCREEN REPRESENTS THE DATA ENTRY LINE. ┬ELOW THAT IS A SOLID LINE RUNNING ACROSS THE SCREEN. ╘HIS CONTAINS SOME USEFUL INFORMATION THAT IS ALWAYS PRESENT ON THE SPREADSHEET PAGE. (╔F YOU HAVE A 64╦ ╓─├ ├128, THE BOTTOM 3 LINES OF THE SCREEN CONTAIN ADDITIONAL REMINDERS.) ╘HE NUMBERS 0-6 REPRESENT COLUMNS. ╘HE LETTERS ┴ THROUGH ╙ ARE THE ROWS. ┬ASIC├ALC HAS THIRTY COLUMNS (0-29) AND TWENTY-SIX ROWS (┴-┌). ┼ACH COLUMN CAN DISPLAY UP TO NINE CHARACTERS. ╬OTICE THAT ONLY SEVEN COLUMNS ARE DISPLAYED ON THE SCREEN. ┴LL THIRTY ARE THERE, YOU JUST CANNOT SEE THEM ALL AT ONCE. ╔MAGINE THAT YOU ARE LOOKING THROUGH A WINDOW AND THAT YOU CAN ONLY SEE A PORTION OF THE OVERALL PICTURE. ┼ACH CELL IN THE SPREADSHEET IS IDENTIFIED BY THE LETTER OF THE ROW FOLLOWED BY THE COLUMN NUMBER. ╞OR EXAMPLE, THE FIRST CELL IS ┴0.
╘HE CURSOR KEYS ALLOW YOU TO MOVE THIS WINDOW AROUND THE SPREADSHEET. ╨RESS '├╒╥╙╧╥ ─╧╫╬' AND THE SPREADSHEET WILL BE QUICKLY REDRAWN WITH ROWS ┬ THROUGH ╘. ┼XPERIMENT WITH THE CURSOR KEYS UNTIL YOU CAN PLACE THE VIEWING WINDOW OVER ALL THE COLUMNS AND ROWS. ╨RESSING '╚╧═┼' WILL RETURN THE WINDOW TO CELL ┴0.
┴S MENTIONED, THE INTERSECTION OF A COLUMN AND A ROW IS CALLED A CELL. ╘HERE ARE 780 CELLS THAT YOU CAN USE, ┴0 THROUGH ┌29. ┴ND THERE ARE THREE TYPES OF INFORMATION THAT YOU CAN ENTER INTO A CELL, TEXT, NUMERIC, OR FORMULAS. ╔N ORDER TO ENTER INFORMATION INTO A CELL YOU NEED TO FOLLOW A SPECIFIC PROCEDURE. ╘YPE IN THE CELL LOCATION, ROW FIRST AND COLUMN SECOND. ╨LEASE LEAVE OUT ANY SPACES. ╬EXT TYPE A COLON. ╘HIS SEPERATES THE CELL LOCATION FROM THE DATA. ╬OW YOU CAN TYPE IN TEXT OR NUMERIC DATA UP TO NINE CHARACTERS IN LENGTH.
╚ERE ARE SOME EXAMPLES.
┴0:┬╒─╟┼╘ 84 (ENTER A TEXT LABEL IN CELL ┴0)
├12:250 (ENTER THE VALUE 250 IN CELL ├12)
─5:-23.12
╘EXT INFORMATION CAN CONTAIN ALMOST ANY CHARACTER ON THE KEYBOARD, BUT MUST NOT BEGIN WITH A NUMBER, OR A PLUS OR MINUS SIGN. ╬UMERIC INFORMATION MUST START WITH A NUMBER OR A PLUS OR MINUS SIGN FOLLOWED BY NUMBERS. ─ECIMAL POINTS ARE ALLOWED IN THE NUMBERS.
┴FTER TYPING IN THE INFORMATION THAT YOU WANT IN A CELL, PRESS ╥┼╘╒╥╬. ╔F EVERYTHING WAS TYPED IN CORRECTLY YOU SHOULD SEE THE DATA IN THE PROPER CELL. ╔T IS VERY IMPORTANT THAT YOU ENTER INFORMATION IN THE PROPER METHOD. ╔F NOT, ┬ASIC├ALC WILL COMPLAIN BY DISPLAYING AN ERROR MESSAGE ON THE DISPLAY LINE. ╘HE MESSAGES ARE DESIGNED TO HELP YOU LOCATE THE PROBLEM. ╫HEN YOU ARE READY TO CONTINUE PRESS A KEY AND SIMPLY RETYPE THE LINE CORRECTLY. ╘EXT DATA IS AUTOMATICALLY LEFT JUSTIFIED. ┘OU CAN INSERT SPACES TO MOVE THE TEXT OVER IF YOU DESIRE. ╬UMERIC DATA WILL BE RIGHT JUSTIFIED.
╘O CLEAR A CELL, SIMPLY TYPE THE CELL COORDINATES FOLLOWED BY A COLON AND THEN PRESS ╥┼╘╒╥╬. ╬OTE THAT THIS WILL NOT CLEAR A FORMULA. ╨RESSING ╙╚╔╞╘-├╠┼┴╥ WILL CLEAR THE ENTIRE SPREADSHEET. ╞OR SAFETY REASONS THIS IS A TWO STEP PROCESS. ╞IRST PRESS ╙╚╔╞╘-├╠┼┴╥ AND THEN ANSWER THE QUESTION ON THE COMMENT LINE. ╨RESSING '┘' WILL CLEAR THE SPREADSHEET. ╨RESS '╬' TO EXIT THE CLEAR MODE.
╒P TO NOW ALL WE HAVE DONE IF CREATE NEAT COLUMNS AND ROWS. ╘HE REAL POWER OF ┬ASIC├ALC IS ITS ABILITY TO COMPUTE MATHEMATICAL EQUATIONS USING THE DATA IN EACH CELL. ╞OR EXAMPLE, WE CAN ADD CELL ┴0 TO CELL ┴1 AND PUT THE ANSWER IN CELL ┴2. ╘HIS IS ACCOMPLISHED BY PUTTING THE FORMULA ┴1+┴2 INTO CELL ┴2. ╚ERE IS THE PROPER FORMAT.
┴2:[╞1]┴1+┴2
╘HE [╞1] APPEARS AS A REVERSE '╞' AND IS PRINTED BY PRESSING THE '╞1' FUNCTION KEY (NOT THE BRACKETS IN THE EXAMPLES). ╘HIS KEY IS USED TO ACCESS SPECIAL FEATURES OF ┬ASIC├ALC. ╔F YOU FORGET TO PRESS '╞1' WHEN ENTERING A FORMULA, THE FORMULA WILL BE ENTERED AS TEXT AND DISPLAYED IN THE CELL. ╬ORMALLY, A FORMULA SHOULD NOT BE DISPLAYED IN A CELL, ONLY THE RESULT OF THE COMPUTATION SHOULD BE PRESENT. ╔F YOU CAN SEE THE FORMULA, IT WAS ENTERED INCORRECTLY AS A TEXT LABEL.
┴ SPECIAL COMMAND ALLOWS YOU TO VIEW THE FORMULA IN A PARTICULAR CELL.
┴2:[╞1]╓
╔F A FORMULA RESIDES IN CELL ┴2, IT WILL BE PRINTED ON THE COMMENT LINE. ╘HE FULL VALUE OF THE NUMERIC DATA IN CELL ┴2 WILL BE PRINTED ALSO. ╘HIS IS IMPORTANT BECAUSE EACH COLUMN IS LIMITED TO NINE CHARACTERS. ┬ASIC├ALC WILL FILL THE CELL WITH ASTERISKS IF THE NUMERIC DATA IS LONGER THAN NINE CHARACTERS. ┘OU WILL THEN NEED TO USE THE VIEW COMMAND TO EXAMINE THAT CELL.
╘HESE ARE THE FORMULAS THAT THIS SPREADSHEET CAN COMPUTE.
ADDITION : CELL + CELL OR CELL + CONSTANT
SUBTRACTION : CELL - CELL OR CELL - CONSTANT
MULTIPLICATION : CELL * CELL OR CELL * CONSTANT
DIVISION : CELL / CELL OR CELL / CONSTANT
EXPONENTIATION : CELL ^ CELL OR CELL ^ CONSTANT
┬ASIC├ALC CANNOT HANDLE COMPLEX FORMULAS INVOLVING MORE THAN TWO CELLS AT ONCE. ┴ MORE INVOLVED COMPUTATION CAN BE DONE BY STORING THE INTERMEDIATE ANSWER IN A SPARE CELL. ╫HEN TYPING IN A FORMULA PLEASE LEAVE OUT ALL SPACES AND YOU MUST ENTER A CELL FIRST AND THE CONSTANT SECOND. ╔F YOUR NEEDS REQUIRE COMPLEX FORMULAS, SPREAD THEM OUT. ╞OR EXAMPLE, IF YOU NEED THE TO DIVIDE THE SUM OF TWO CELLS BY ANOTHER CELL, IT IS A TWO STEP PROCESS.
┴2:[╞1]┴0+┴1
┴4:[╞1]┴2/┴3
╘HIS ADDS ┴0 AND ┴1, THEN DIVIDES THAT VALUE BY THE CONTENTS OF ┴3, WITH THE RESULTS IN ┴4.
╞ORMULAS ARE NOT CALCULATED IMMEDIATELY. ╔N ORDER TO CALCULATE THE SPREADSHEET YOU MUST PRESS THE LEFT ARROW KEY (_). (╘HIS IS THE TOP LEFT KEY ON THE KEYBOARD UNDER THE ┼╙├ KEY.) ├ALCULATING TAKES A WHILE DEPENDING UPON THE NUMBER OF FORMULAS IN THE SPREADSHEET. ╬ORMALLY YOU WILL MAKE ALL YOUR CHANGES AND CALCULATE JUST ONCE. ├ALCULATIONS ARE DONE COLUMN BY COLUMN FROM TOP TO BOTTOM. ├OLUMN ONE WILL BE COMPLETELY DONE BEFORE COLUMN TWO. ╘HIS IS AN IMPORTANT POINT TO REMEMBER, AND IF YOU FORGET IT YOUR CALCULATIONS MAY COME OUT INCORRECT!
╞OR EXAMPLE, LET CELL ┴0=╞9*╟6. ╔F CELL ╞9 HAS A FORMULA IN IT, THE RESULTING ANSWER WILL BE FIGURED AFTER CELL ┴0 IS COMPUTED. ╘O OVERCOME THIS, YOU SHOULD PRESS THE LEFT-ARROW KEY TWICE (CALCULATE TWICE). ┴FTER ALL COMPUTATIONS ARE COMPLETE, THE SPREADSHEET WILL BE REDRAWN WITH THE RESULTS DISPLAYED IN THE PROPER CELLS. ┴TTEMPTS TO DIVIDE BY ZERO WILL BE NOTED IN THAT CELL AND IF A EXPONENTIATION CALCULATION IS TOO LARGE AN OVERFLOW NOTE WILL BE DIPLAYED IN THAT CELL.
┬ASIC├ALC HAS A FEW EXTRA SPECIAL FORMULAS WHICH ARE VERY USEFUL.
┴1:[╞1]╙╒═┴2-┌2
╘HIS COMMAND PUTS THE SUM OF CELLS ┴2 THROUGH ┌2 INTO CELL ┴1. ╓ERY USEFUL FOR ADDING UP LONG COLUMNS OR ROWS.
┌29:[╞1]┴╓╟┬3-┬12
╘HIS COMMAND CALCULATES THE AVERAGE OF CELL ┬3 THROUGH ┬12 AND PUTS THE ANSWER INTO CELL ┌29
├12:[╞1]═╔╬─0-╟0 ╘HIS COMMAND LOOKS FOR THE MINUMUM FIGURE OVER A RANGE OF CELLS AND PUTS THE ANSWER IN CELL ├12
╞5:[╞1]═┴╪┌0-┌29 ╘HIS IS SIMILAR TO THE ═╔╬ COMMAND EXCEPT IT RETURNS THE MAXIMUM VALUE IN A RANGE.
┘OU CAN USE ANY CELLS THAT YOU WISH BUT THEY MUST BE EITHER IN A STRAIGHT COLUMN OR ROW.
╚ERE IS AN EXAMPLE OF AN INCORRECT FORMAT.
┌29:[╞1]╙╒═┴0-─29
╘HIS FORMULA WILL NOT WORK BECAUSE CELLS ┴0 THROUGH ─29 ARE IN A DIAGONAL LINE, NOT A STRAIGHT LINE.
╚ERE ARE THE REST OF ┬ASIC├ALC'S SPECIAL FEATURES.
├15:[╞1]├ ╘HIS COMMAND WILL CLEAR AN INDIVIDUAL CELL INCLUDING THE FORMULA, TEXT, AND NUMERIC DATA.
╞25:[╞1]╩ ╘HIS COMMAND JUMPS THE DISPLAY TO A PARTICULAR AREA OF THE SPREADSHEET. ╙OMETIMES THIS IS FASTER THAN USING THE CURSOR KEYS TO MOVE THE DISPLAY WINDOW.
─3:[╞1]├╧╨─4-─29 ╘HIS COMMAND IS USED WHEN YOU ARE ENTERING LOTS OF IDENTICAL INFORMATION. ╔N THIS EXAMPLE THE CONTENTS OF CELL ─3 WILL BE COPIED INTO CELLS ─4 THROUGH ─29. ╧NLY TEXT OR NUMERIC INFORMATION WILL BE COPIED. ╞ORMULAS MUST BE TYPED INDIVIDUALLY. ╘HIS WORKS WITH ROWS OR COLUMNS.
╞╒╬├╘╔╧╬ ╦┼┘╙
╨RESS ╞6 AND YOU WILL SEE A MAXIMUM PRECISION DISPLAY ON THE COMMENT LINE. ╘HIS COMMAND DOES NOT AFFECT THE ACCURACY OF THE CALCULATIONS. ╔T ROUNDS THE NUMBER FOR DISPLAY PURPOSES. ╒SE THE ╓IEW COMMAND TO SEE THE FULL VALUE. ╨RESS A NUMBER FROM ZERO TO SIX. ┌ERO MEANS INTEGERS AND SIX MEANS SIX DECIMAL PLACES. ┬ASIC├ALC IS AUTOMATICALLY SET UP FOR TWO DECIMAL PLACES AUTOMATICALLY. ╘HIS COMMAND IS ONLY FOR NUMBERS THAT ARE COMPUTED BY A FORMULA. ╔F YOU WANT TWO PLACE DECIMALS ON ALL THE NUMBERS YOU MUST TYPE THEM THAT WAY.
╨RESS ╞4 AND FOLLOW THE SCREEN DIRECTIONS TO SAVE THE SPREADSHEET TEMPLATE TO DISK. ╨ICK OUT A LOGICAL FILENAME FOR THE TEMPLATE. ╔T WILL HAVE THE PREFIX ╙╨╥─. ADDED TO IT.
╨RESS ╞2 AND FOLLOW THE SCREEN DIRECTIONS TO LOAD THE SPREADSHEET TEMPLATE FROM TAPE OR DISK. ╧R YOU CAN USE THE DIRECTORY MENU (╞8) AND CHOOSE LOAD A SPREADSHEET. ╘HIS WILL SHOW YOU ALL THE SPREADSHEETS ON THE CURRENT DISK. ╘O LOAD ONE JUST USE THE CURSOR KEYS TO HIGHLITE YOUR SELECTION AND PRESS RETURN.
╘O PRINT THE SPREADSHEET TEMPLATE ON PAPER, PRESS ╞5 AND FOLLOW THE SCREEN DIRECTIONS. ┘OU CAN PRINT THE WHOLE TEMPLATE OR ANY PORTION OF IT. ┘OU WILL NEED TO KNOW THE TOP-LEFT CELL COORDINATES AND THE BOTTOM-RIGHT CELL COORDINATES OF THE AREA THAT YOU WANT PRINTED OUT. ╔F YOU SPECIFY MORE THAN SEVEN COLUMNS, ┬ASIC├ALC WILL AUTOMATICALLY BREAK THE PRINTOUT INTO SECTIONS FOR YOU. ╘O PRINT JUST THE FORMULAS ON PAPER, PRESS ╞3 AND FOLLOW THE SCREEN DIRECTIONS.
╟╥┴╨╚╙
╞7 PUTS YOU IN THE ┬ASIC├ALC GRAPH SCREEN. ╚ERE YOU CAN GENERATE SIMPLE BAR, PIE AND LINE GRAPHS FROM YOUR DATA. ╘HE DATA MUST BE IN A LINE, IN OTHER WORDS THE SAME ROW OR COLUMN.
┬AR GRAPHS ARE THREE DIMENSIONAL. ╘HEIR SIZE DEPENDS ON THE NUMBER OF POINTS YOU ARE GRAPHING. ╘HE HEIGHT IS SET SO THAT THE LARGEST DATA ITEM NEARLY REACHES THE TOP OF THE GRAPH AREA. ╘HE VALUE OF EACH BAR IS PRINTED ABOVE IT.
╘HE PIE CHART CREATS A SEGMENTED PIE GRAPH, WITH DIFFERENT PATTERNS FOR EACH ITEM. ╘HE LARGEST DATA ITEM IS PULLED OUT FROM THE MAIN PIE. ┼ACH PIE WEDGE HAS ITS VALUE PRINTED NEAR IT.
╘HE LINE GRAPH IS A FORM OF NON-LINEAR REGRESSION, OR BEST FIT CURVE. ╔T GENERATES A CURVED LINE THAT ATTEMPTS TO SHOW THE RELATIONSHIP OF THE DATA. ╘HIS GRAPH IS NOT THAT USEFUL FOR MOST APPLICATIONS. ╘HERE ARE NO LABELS IN THIS GRAPH.
╧NCE YOUR GRAPH IS COMPLETED, A NEW SET OF CURSOR DRIVEN COMMANDS APPEAR. ╘HESE ALLOW YOU TO EITHER RETURN TO THE SPREADSHEET, GRAPH AGAIN, OR SAVE THE SCREEN TO DISK (SNAPSHOT) AS A PICTURE WHICH CAN BE USED IN PROGRAMS LIKE ┬ASIC╫RITE OR ┬ASIC╨AINT. ┘OU CAN ALSO PRINT THE SCREEN ON YOUR PRINTER.
╨╥╔╬╘┼╥╙
┬EFORE ATTEMPTING TO PRINT ANY SCREENS YOU SHOULD MAKE SURE YOU HAVE INSTALLED THE CORRECT PRINTER DRIVER. ╘O DO THAT, FROM THE MAIN SPREADSHEET PRESS ╞8. ╘HIS TAKES YOU TO THE DIRECTORY MENU. ╚ERE YOU CAN LOOK AT A DIRECTORY OF ALL THE FILES ON THE CURRENT DISK, ALL THE SPREADSHEETS AVAILABLE, OR ALL THE PRINTER DRIVERS ON THE DISK. ╫HEN YOU FIRST START UP ┬ASIC├ALC, IT IS A GOOD IDEA TO INSTALL THE PROPER PRINTER DRIVER. ╙O PRESS ╞8, SELECT ╨ FOR PRINTERS, AND USE THE CURSOR KEYS TO SELECT THE PROPER DRIVER. ╔T WILL BE LOADED INTO MEMORY.
┴FTER INSTALLING THE PRINTER DRIVER, YOU SHOULD SET THE PROPER SECONDARY ADDRESS FOR YOUR PRINTER AND ITS INTERFACE, AS WELL AS THE HEIGHT AND DENSITY OF THE OUTPUT. ┘OU CAN EVEN SET THE PRINTED PICTURE TO BE ROTATED IF YOUR PRINTER DRIVER SUPPORTS ROTATION.
╘O DO THIS YOU MUST USE THE EXTENDED COMMANDS. ╘HESE ARE ENTERED FROM THE SPREADSHHEET COMMAND LINE AND ARE PREFIXED WITH THE ASTERICK (*). ╚ERE IS A LIST OF THE EXTENDED COMMANDS.
*DIR ' GIVES THE DIRECTORY MENU, JUST LIKE PRESSING ╞8
*QUIT ' EXITS THE SPREADSHEET PROGRAM AND RETURNS TO BASIC
*DRIVE= ' CHANGES DEFAULT DRIVE AND ACCEPTS DRIVE NUMBERS 8-11
*SETTIME= ' SET THE ├128 CLOCK...ENTER IN 24 HOUR FORMAT ╚╚══╙╙
*CLOCKON ' DISPLAY THE TIME (IT IS DISPLAYED IN 12 HOUR FORMAT)
*CLOCKOFF ' TURN OFF THE CLOCK DISPLAY
