DOCUMENTATION FOR THE CAD SYSTEM.VERSION 3.0.BY STEPHEN P. NYE.70366,1316...THE CAD SYSTEM WAS WRITTEN TO DO ELECTRONIC SCHEMATICS AND OTHER LINE DRAWINGS ON TH E COMMODORE 64. IT IS BASED ON A PACKAGE OF USR CALLS (USERML) FOUND ON THE.COMM ODORE SIG OF THE COMPUSERVE INFORMATION SERVICE...THE SYSTEM WILL SUPPORT ONE OR TWO DRIVES. IT WILL DEFAULT TO THE TWO DRIVE OPTION. TO USE CAD WITH ONLY ONE D RIVE ALL YOU HAVE TO DO IS ANSWER '8' TO THE FILE.DISK PROMPT THAT APPEARS WHEN THE PROGRAM IS FIRST BOOTED. THE DEFAULT CAN EASILY BE CHANGED. JUST LOAD THE 'B OOT' PROGRAM AND LIST THE FIRST LINE. TH ERE IS A.DEFINITION STATEMENT FOR D1 (D1 =???). JUST REPLACE THIS STATEMENT WITH 'D1=D0'. THEN SCRATCH THE OLD BOOT AND S AVE THE NEW VERSION. TO AVOID CONFUSION, THIS.DOCUMENTATION WILL ASSUME THAT TWO DRIVES ARE USED AND THE DRIVES ARE ASSI GNED AS FOLLOWS:.. DRIVE NUMBER 8 CO NTAINS THE PROGRAM DISK.. DRIVE NUMB ER 9 CONTAINS THE FILE DISK...NOTE: THE CAD SYSTEM IS VERY DISK INTENSIVE. IT IS CONTINUOUSLY ACCESSING NEW INFORMATION ON THE DISK DRIVE. FOR THIS REASON IT IS VERY IMPORTANT NOT TO REMOVE.THE PROGRA M DISK FROM THE DRIVE UNLESS PROMPTED BY THE PROGRAM TO DO SO...THE CAD SYSTEM W ILL SUPPORT EITHER A JOYSTICK OR THE 135 0 MOUSE PLUGGED INTO PORT 2 OF THE COMPU TER......GETTING STARTED..TO USE THE CAD , TYPE "LOAD 'BOOT',8" AND THEN "RUN"... THE FIRST PROMPT WILL ASK FOR THE FILE D RIVE NUMBER. IF YOU ARE USING TWO DRIVES , THIS PROMPT WILL DEFAULT TO THE 'OTHER ' DRIVE. THE SYSTEM DETECTS WHICH DRIVE. WAS USED FOR THE BOOT AND ASSIGNS THE FI LES TO THE SECOND DRIVE. TO ACCEPT THE D EFAULT JUST PRESS RETURN. TO ENTER A DRI VE ASSIGNMENT OTHER THAN THE DEFAULT.JUS T PRESS THE NUMBER OF THE DRIVE (NO RETU RN)...THE SYSTEM WILL THEN PRESENT A CRE DITS SCREEN. THESE PEOPLE HAVE BEEN MAJO R CONTRIBUTORS TO THE DEVELOPMENT OF THE CAD PACKAGE. THEN THE SYSTEM WILL SHOW THE.LOADING OF THE THREE MAJOR MACHINE L ANGUAGE PACKAGES USRML, SYSPKG AND SYSPK GII. ..YOU WILL THEN BE PROMPTED WHETHER TO 'ERASE PRESENT SCREEN'. THIS PROMPT IS PRESENT AS A SAFEGUARD AGAINST A SYST EM CRASH. SHOULD YOU SUFFER A CRASH WHIL E.WORKING ON A HIRES SCREEN, DO NOT TURN OFF THE COMPUTER. PRESS RUN/STOP RESTOR E. THE SCREEN WILL CLEAR BUT THE CURSOR WILL NOT BE VISIBLE. CAREFULLY TYPE.SYS6 4738 AND PRESS RETURN. THE COMPUTER SHOU LD DO A COLD BOOT AND YOU WILL SEE THE C OMMODORE START-UP SCREEN. LOAD THE 'BOOT ' PROGRAM AS BEFORE AND WHEN.PROMPTED FO R 'ERASE PRESENT SCREEN' ANSWER BY PRESS ING 'N' (OR ANYTHING BUT 'Y'). THE HIRES SCREEN YOU WERE WORKING ON SHOULD STILL BE INTACT AND YOU CAN.RESUME WORKING... AFTER ANSWERING THE ERASE PROMPT, THE SY STEM WILL DELAY A SHORT TIME AND THEN LO AD THE MAIN MENU. THIS IS ONE OF THREE M ENUS IN THE SYSTEM. THE OTHERS ARE.REACH ED BY PRESSING M, M OR COMMODORE(C=) M. IT IS NOT NECESSARY TO GO TO A MENU TO M OVE FROM ONE PROGRAM TO ANOTHER. IN MOST CASES, JUST PRESS THE KEY FOR THE.COMMA ND YOU DESIRE AND THE SYSTEM WILL AUTOMA TICALLY LOAD THE NECESSARY INFORMATION F OR THAT COMMAND. IF AT ANY TIME YOU GET LOST A SERIES OF RETURNS SHOULD.GET YOU BACK TO THE MAIN MENU...WHILE VIEWING TH E MAIN MENU IT SHOULD BE POINTED OUT THA T THERE ARE SEVERAL COMMAND KEYS THAT WO RK FROM WITHIN ALMOST ALL FUNCTIONS. THE Y ARE:..! -> ALLOWS YOU TO TOGGLE BETWEE N THE TWO AVAILABLE HIRES SCREENS (SCREE N 1 IS ALWAYS THE SCREEN BEING VIEWED).. .# -> INVERTS SCREEN 1. TURNS ON ALL OFF PIXELS AND TURNS OFF ALL ON PIXELS...& -> ADDS SCREEN 2 TO SCREEN 1. SCREEN 2 I S UNAFFECTED BY THIS OPERATION...= -> CO PIES SCREEN 1 TO SCREEN 2. THE INFORMATI ON IN SCREEN 2 IS LOST...CLR -> PRESSING THE CLEAR KEY WILL ERASE SCREEN 1...DEL -> PRESSING THE DEL KEY WILL NORMALLY U NDO THE LAST DRAW PERFORMED. THIS FUNCTI ON WILL NOT WORK IF THE MOUSE BUTTON, OR ANOTHER COMMAND KEY, HAS BEEN.PRESSED S INCE THE LAST DRAW......TYPICAL OPERATIO N..BEFORE LOOKING AT ALL THE COMMANDS AV AILABLE, LET'S TAKE A LOOK AT HOW A TYPI CAL COMMAND FUNCTION WILL WORK. FOR OUR EXAMPLE WE WILL USE THE 'B'OX ROUTINE. T O.ACCESS THIS ROUTINE PRESS 'B' WHEN THE MAIN MENU APPEARS...WHEN YOU PRESS 'B' THE SYSTEM WILL ACCESS THE DRIVE FOR A S HORT TIME AND THEN THE HIRES SCREEN WILL APPEAR. A CROSSHAIRS WILL APPEAR ON THE HIRES SCREEN. THIS.IS THE HIRES CURSOR. YOU CAN MOVE THIS CURSOR AROUND THE HIR ES SCREEN USING THE MOUSE. NOTICE THAT T HE CURSOR MOVES IN 6 DOT INCREMENTS. THE NUMBER OF DOTS.THAT THE CURSOR MOVES EA CH TIME IS ADJUSTABLE FROM 1 TO 9 BY PRE SSING THE APPROPRIATE NUMBER. THERE IS A LSO A 'SUPERSPEED' VALUE OF 25 AVAILABLE BY PRESSING 0..YOU WILL FIND THAT THIS FEATURE ALLOWS YOU TO MOVE AROUND THE SC REEN AT A FAST PACE, WHILE ALSO ALLOWING YOU EXACT PIXEL PLACEMENT...MOVE THE CU RSOR TO A POINT THAT WILL BE ONE CORNER OF THE BOX YOU WISH TO DRAW AND PRESS TH E MOUSE BUTTON. YOU WILL NOTICE THAT A S MALL CROSS APPEARS IN THE.CENTER OF THE CURSOR. WHEN YOU MOVE THE CURSOR THE CRO SS WILL REMAIN IN PLACE TO REMIND YOU OF WHERE THE FIRST POINT WAS PLACED. MOVE TO THE POINT THAT WILL BE.THE DIAGONALLY OPPOSITE CORNER OF THE BOX AND PRESS TH E MOUSE BUTTON AGAIN. THE CAD WILL DRAW A BOX USING THESE TWO POINTS TO DETERMIN E WHERE THE LINES WILL.BE. IF YOU MAKE A MISTAKE JUST PRESS DEL AND THE BOX WILL BE ERASED...NOTE THAT IN THIS, AS MOST ROUTINES, YOU MAY USE THE COMMAND KEYS ! # & = CLR AND DEL......DRAWING ROUTINES ..WHAT FOLLOWS IS A LIST OF THE AVAILABL E COMMANDS. THEY ARE LISTED ALPHABETICAL LY; LOWER CASE, UPPER CASE AND THEN COMM ODORE(C=) KEY. IN THESE DESCRIPTIONS, TH E.TERM MARKER REFERS TO THE SMALL CROSS THAT IS PLACED ON THE HIRES SCREEN EACH TIME THE MOUSE BUTTON IS PRESSED. MOST R OUTINES CAN BE EXITED BY PRESSING ANY.CO MMAND KEY, AND ALL ROUTINES CAN BE EXITE D BY PRESSING RETURN...A -> ARCS USES TW O MARKERS TO DETERMINE THE BEGINNING AND END OF A QUARTER CIRCLE. THE CIRCLE SEG MENT IS ALWAYS DRAWN COUNTER-CLOCKWISE F ROM THE FIRST MARKER.TO THE SECOND...A - > BROKEN LINES USES TWO MARKERS TO DETER MINE THE BEGINNING AND END OF A DASHED L INE. WHEN YOU CHOOSE THIS KEY, YOU WILL BE PROMPTED FOR THE LENGTH OF THE.LINE S EGMENT, AND THE LENGTH OF THE SPACE BETW EEN LINE SEGMENTS. NOTE THAT BROKEN LINE S CAN BE DRAWN ONLY HORIZONTALLY AND VER TICALLY...C=A -> LOAD DOODLE COMPRESSED FORMAT. WILL LOAD A CSLIDE FORMAT HIRES FILE INTO SCREEN 1. WHEN THE LOAD IS COM PLETE YOU WILL BE PRESENTED WITH TWO OPT IONS..PRESSING '!' WILL SWITCH THE SCREE N 1 INFORMATION INTO SCREEN 2 AND ALLOW YOU TO LOAD ANOTHER FILE INTO SCREEN 1. THE INFORMATION IN SCREEN 2 WILL BE LOST ..PRESSING '*' WILL ALLOW YOU TO RE-TRY A LOAD INTO SCREEN 1 IN CASE YOU MIS-TYP E THE FILENAME OR PLACE THE WRONG DISK I N THE FILE DRIVE. THE PREFIX 'JJ' IS.AUT OMATICALLY ADDED TO THE FILENAME...B -> BOX WILL USE TWO MARKERS TO INDICATE DIA GONALLY OPPOSITE CORNERS OF A RECTANGLE. ..B -> BOXES (SOLID) USES TWO MARKERS AS IN BOX. THE RECTANGLE IS FILLED WITH TH E FOREGROUND COLOR...C=B -> SAVE DOODLE COMPRESSED FORMAT. WILL SAVE SCREEN 1 IN CSLIDE FORMAT. WHEN THE SAVE IS FINISHE D, YOU WILL BE PRESENTED WITH THE SAME T WO OPTIONS AS IN.C=A. THE INFORMATION IN SCREEN 2 WILL NOT BE LOST BY CHOOSING ' !'. THE PREFIX 'JJ' IS AUTOMATICALLY ADD ED TO THE FILENAME...C -> CIRCLES (DIAME TER) WILL USE TWO MARKERS TO INDICATE TH E DIAMETER OF A CIRCLE. THE SYSTEM WILL AUTOMATICALLY CALCULATE THE CENTER AND D RAW THE CIRCLE. BY.PRESSING '+' BEFORE P LACING THE FIRST MARKER YOU MAY TOGGLE A CENTER MARKER ON AND OFF. IF ON, THIS W ILL PLACE A SMALL + AT THE CENTER OF THE CIRCLE WHEN.DRAWN...C -> CIRCLES (RADIU S) WILL USE THE FIRST MARKER AS THE CENT ER OF THE CIRCLE. THE SECOND MARKER WILL DETERMINE THE RADIUS OF THE CIRCLE. THE CENTER MARKER IS.ALSO AVAILABLE IN THIS COMMAND...C=C -> YOU WILL BE PRESENTED WITH A MENU OF FUNCTION KEY DEFINITIONS. WHEN YOU PRESS ONE OF THE KEYS, THE SYS TEM WILL SWITCH TO THE HIRES SCREEN. USI NG THE.FUNCTION KEYS YOU MAY CYCLE THROU GH THE AVAILABLE COLORS FOR FOREGROUND, BACKGROUND, AND CURSOR COLOR. THE SYSTEM WILL KEEP THESE COLORS UNTIL THEY ARE A GAIN.CHANGED OR THE SYSTEM IS RE-BOOTED. YOU MAY CHANGE THE DEFAULT COLORS BY CH ANGING THE DEFINITIONS IN THE 'BOOT' PRO GRAM. THE LINES ARE REM'ED. (SEE N) TO E XIT.
