===================================================================== *** JJB 1.2 for QUICK C and TURBO C programmers *** ===================================================================== Welcome, Turbo C and Quick C programmers, to JJB 1.2 JJB is a high-level programming environment you may use under the Shareware concept to program ANY PROGRAMMING APPLICATION including: graphics, communication, data base, utilities, etc. The code is tight and executes your program fast. JJB 1.2 is the first in a series of software products I am writing which enables the 'C' programmer to write professional looking programs in minutes instead of taking days, weeks, or even months. I hope you enjoy using JJB and I welcome you to become a registered user so you can share in all the advantages that programming with JJB has to offer. I am currently working on my next release JJB LA (Large Application).

New, different, unique. 2. A high-level, C programming environment. 3. Professionally written and completely documented. 4. Designed for Quick C and Turbo C programmers. 5. JJB 1.2 is included with this literature and is ready to use. 6. Easy to install. Easy to begin using. 7. Executes your program fast--direct memory access. 8. Makes your program portable: Runs on IBM PC, XT, AT 286, 386 and compatible computers with monochrome, CGA, EGA, VGA, etc. 9. Allows C programs to be written in minutes. 10. Distributed under the Shareware concept. JJB is a foundation of functions from low-level to high-level upon which you can build your program. The functions execute fast and are coded tight to conserve memory for your program. With them, you can program in an extreme high-level 'C' environment maintaining complete low-level control over your program. JJB automatically handles many things for you such as making pull-down menus, testing each keypress, handling color attributes for the different video modes, changing from one option to another, and many more routine tasks you should not have to do. JJB actually executes (runs) your program. JJB handles every keypress in your program. From any option in your program, you can select, and go to any other option. Each option can be initalized and exited with a function. You never have to test a keypress. ===================================================================== *** FOR CLUBS AND COMPANIES DISTRIBUTING SHAREWARE SOFTWARE *** ===================================================================== This is the complete JJB 1.2 programming environment designed especially for QUICK C and TURBO C programmers. JJB is a programming environment which allows the 'C' programmer to easily and quickly write professional looking programs. I am the author and you have my permission to freely circulate it under the Shareware concept as long as you do not add, delete or change JJB files. The documentation is complete with over 50 pages including five sample source files all of which can be printed with one dos command. Installation is as easy as placing the diskette in drive a: and entering the installation command. Within one minute it will be installed. There is a learning installation, a final installation and even a reverse installation for keeping your hard disk free of unnecessary files. This file 'JJB-READ.DOC' explains everything the QUICK C and TURBO C programmer needs to get started. All documentation can be printed from dos by entering 'JJBPRINT'. John James Broderick JJB 9236 Church Rd, Suite 1082 Dallas, Tx. 75231 (214) 341-1635 ====================================================================== *** JJB 1.2 for QUICK C and TURBO C programmers *** ---------------------------------------------------------------------- *** Distributed under the Shareware concept. Registration $49 *** ====================================================================== JJB 9236 Church Rd, Suite #1082 Dallas, Texas 75231 (214) 341-1635 USE JJB TO WRITE QUICK C AND TURBO C PROGRAMS FAST. JJB HANDLES EXECUTING YOUR PROGRAM FUNCTIONS. IT AUTOMATICALLY DOES YOUR PULL-DOWN MENUS, OPTION SELECTION, FAST WINDOWING, ENTRY INPUT, AND IS 100% PORTABLE. ANY BEGINNING 'C' PROGRAMMER CAN START USING JJB IN MINUTES. JJB IS A SET OF FUNCTIONS AND ARRAYS WHICH HOLDS INFORMATION ABOUT YOUR PROGRAM OPTIONS. EACH OPTION CAN BE ASSIGNED A STRING DESCRIPTION AND A FUNCTION NAME. THEY ARE GROUPED TOGETHER TO FORM PULL-DOWN MENUS AND BOTH OPTIONS AND GROUPS CAN BE INITALIZED AND EXITED WITH PROGRAM FUNCTIONS. FROM ANY OPTION IN YOUR PROGRAM, YOU CAN SELECT ANY OTHER OPTION BY PRESSING 'ALT' AND MAKING A SELECTION FROM THE PULL-DOWN MENUS, OR YOU CAN PRESS AN ASSIGNED FUNCTION KEY GOING DIRECTLY TO THE OPTION. JJB HANDLES CHANGING OPTIONS BY EXECUTING THE FUNCTION FOR THE OPTION SELECTED. JJB IS DESIGNED SO THE SOFTWARE YOU WRITE TODAY WILL RUN ON EVERY IBM PC, XT, AT 286, 386 AND COMPATIBLE COMPUTER AND ON ALL VIDEO CONTROLLERS MONOCHROME, CGA, EGA, VGA, ETC, PLUS IT SHOULD ALSO RUN ON UPWARD-COMPATIBLE COMPUTERS MADE IN THE FUTURE. FEATURES INCLUDE: DIRECT MEMORY ACCESS--OVER 30 'VIDEO FAST' 'VF' FUNCTIONS PROGRAMMED FOR TIGHT, PORTABLE KILLER SPEED, EASY COLORING AND WINDOWING, COMPLETE SET OF KEYBOARD FUNCTIONS FOR HIGH-LEVEL DATA ENTRY, KEYBOARD TESTING IS ALL AUTOMATIC AND DONE BY JJB, YET YOU CAN OVERRIDE FOR LOW-LEVEL CONTROL. YOU CAN GENERATE INTERNAL USER KEYPRESSES, INPUT FUNCTIONS CAN EDIT FROM/TO INPUT RANGES, ENTER FUNCTIONS DIRECTLY UPDATE DATA BUFFERS, GET AND SET FUNCTIONS ALLOW LOW-LEVEL CONTROL TO ACCESS OR CHANGE SWITCHES AND VARIABLES. JJB PROVIDES A HIGH-LEVEL PROGRAMMING ENVIRONMENT FOR THE BEGINNING 'C' PROGRAMMER AND LOW-LEVEL CONTROL FOR THE ADVANCED PROGRAMMER. REGISTRATION IS $49. PLUS $3. SHIPPING. REGISTERING ENTITLES YOU TO RECEIVE THE LATEST VERSION OF ALL JJB SOFTWARE, THE JJB MANUAL (THE COMPLETE PRINTED DOCUMENTATION), SOURCE CODE WITH COMMENTS FOR ALL INPUT AND ENTER FUNCTIONS, FREE TECHNICAL SUPPORT, AND THE JJB NEWSLETTER. ====================================================================== *** Where did the idea of JJB for 'C' come from ? *** ---------------------------------------------------------------------- *** From a 1988 INCOME TAX PACKAGE written in FORTH. *** ====================================================================== JJB FOR 'C' PROGRAMMERS REPRESENTS THE BEST OF WHAT I KNOW AND WHAT I HAVE PROGRAMMED SINCE I WROTE THE FIRST ASSEMBLY LANGUAGE TRACE, STEP, BREAKPOINT DEBUGGER FOR THE APPLE II COMPUTER IN 1979. IT WAS KNOWN AS "JOHN'S DEBUGGER" AND SOLD THOUSANDS OF COPIES IN THE US, JAPAN AND WORLDWIDE. FOR SOME REASON THE JAPANESE LIKED IT A LOT. MY NEXT MAJOR PRODUCT WAS AN ASSEMBLY LANGUAGE GENERAL LEDGER PACKAGE FOR THE APPLE II COMPUTER. I HAD WORKED WITH HUNDREDS OF COMPUTERIZED ACCOUNTING SYSTEMS AS A CPA AND NEVER FOUND ONE I LIKED, SO I WROTE ONE TO BE SUPER FAST AND MARKETED IT WORLDWIDE. I THINK IT IS STILL THE FASTEST GENERAL LEDGER AVAILIABLE FOR THE APPLE II TODAY. MY USERS ARE VERY LOYAL AND CALL ME ALL THE TIME JUST TO CHAT. IN 1983 I SWITCHED FROM ASSEMBLY LANGUAGE TO FORTH. ALL MY ASSEMBLY LANGUAGE ROUTINES HAD TO BE REWRITTEN IN FORTH. FOR THOSE OF YOU WHO DON'T KNOW, WHEN YOU WRITE IN FORTH YOU HAVE TO RE-INVENT THE WHEEL SO TO SPEAK. SINCE THEN I HAVE WRITTEN EIGHT SOFTWARE PRODUCTS IN FORTH FOR THE IBM PC, XT, AND AT. ALL OF WHICH RUNS ON EVERY IBM AND COMPATIBLE. I HAVE NOT ENCOUNTERED A COMPATIBLE COMPUTER WHICH IT DOES NOT RUN ON. THE IDEA FOR 'JJB' CAME TO ME LAST YEAR WHEN I DID A COMPLETE 1040 INCOME TAX PACKAGE IN FORTH. FROM ANY LINE ON ANY FORM, THE USER HAD TO BE ABLE TO GO DIRECTLY TO ANY LINE ON ANY OTHER FORM, INSTANTLY. FORMS WERE AUTOMATICALLY INITALIZED OR READ, AND UPDATED UPON EXITING. IN 1988 I CONVERTED MY FORTH ROUTINES TO 'C'. THE LANGUAGES ARE VERY SIMILIAR. IN DOING SO I WANTED AN EXTREMELY HIGH-LEVEL PROGRAMMING ENVIRONMENT WITH ABSOLUTE LOW-LEVEL CONTROL. THE RESULT IS 'JJB 1.2'. I AM CURRENTLY WORKING ON JJB LA (LARGE APPLICATION) WHICH SHOULD BE READY FOR RELEASE SOON. JOHN JAMES BRODERICK ===================================================================== *** SUMMARY OF DOCUMENTATION, INSTALLATION, and REGISTRATION *** ===================================================================== This file and the files listed below, document JJB 1.2 explaining what it does and how to use it. The JJBSHOW files provide you with more information so you can begin programming with JJB. The two header files JJBKBD.H and JJBSET.H give you even more documention. You can print them all with the .bat file 'JJBPRINT.BAT' from DOS by entering: 'JJBPRINT' JJB-READ.DOC JJBKBD.H JJBSET.H JJBSHOW1.C JJBSHOW2.C JJBSHOW3.C JJBSHOW4.C JJBSHOW5.C Installing JJB is easy. Basically you just place the diskette with the JJB files in drive a: and enter one of the four DOS commands: JJBQC-LI (Quick C learning installation) JJBQC-FI (Quick C final installation) JJBTC-LI (Turbo C learning installation) JJBTC-FI (Turbo C final installation) All of this is explained is detail further down in this file. This is just a summary here to show you how easy it is. Two installation methods are provided. One is the learning installation, the other is the final installation. Both are the same except the final installation only moves files to the hard disk which are necessry for programming with JJB. Installation is designed so you do not have to create a separate directory for JJB. Every JJB filename begins with the three letters 'JJB'. All JJB files can easily be removed from any directory with the following DOS command: 'JJBREMOV' -------------- JJB MANUAL (THE PRINTED DOCUMENTATION) --------------- A manual is available and will be sent to you if you register. It is the tenth manual I have written and sometimes I think it is harder to write the manual then it is to write the software. If you think the manual will be the same as this documentation, not so. Both were written separately without referring to each other so that each compliments and adds to the other. Those who register will also receive the latest version of all JJB software, the complete source code with comments for all the input and enter functions, free technical support, and the JJB newsletter. ========================================================================= *** JJB FILES *** ========================================================================= JJB-READ.DOC (THIS FILE ) JJB-FORM.DOC (REGISTRATION FORM ) JJBFILES.DOC (LIST OF ALL JJB FILES ) JJBINSTL.DOC (HOW TO INSTALL JJB FOR QUICK C & TURBO C ) JJBPRINT.BAT (PRINTS ALL JJB FILES WHICH HAVE DOCUMENTATION ) JJB.EXE (A DEMO-IF YOU CAN DEMO A PROGRAMMING ENVIRONMENT ) JJBSHOW5.EXE (EXECUTABLE FILE OF SOURCE FILE 'JJBSHOW5.C' ) JJBKBD.H (HEADER FILE FOR KEYBOARD DEFINITIONS ) JJBSET.H (HEADER FILE FOR GET & SET DEFINITIONS ) JJBQC-LI.BAT (.BAT FILE FOR QUICK C LEARNING INSTALLATION ) JJBQC-FI.BAT (.BAT FILE FOR QUICK C FINAL INSTALLATION ) JJBTC-LI.BAT (.BAT FILE FOR TURBO C LEARNING INSTALLATION ) JJBTC-FI.BAT (.BAT FILE FOR TURBO C FINAL INSTALLATION ) JJBREMOV.BAT (.BAT FILE FOR REVERSE INSTALLATION REMOVING FILES ) JJBQC.OBJ (QUICK C OBJECT FILE FOR JJB INPUT & ENTER FUNCTIONS) JJBQCINP.OBJ (QUICK C OBJECT FILE FOR JJB INPUT & ENTER FUNCTIONS) JJBQCDOL.OBJ (QUICK C OBJECT FILE FOR JJB INPUT DOLLAR FUNCTIONS ) JJB.QLB (QUICK C JJB LIBRARY CREATED WHEN INSTALLED ) JJBTC.OBJ (TURBO C OBJECT FILE FOR JJB ) JJBTCINP.OBJ (TURBO C OBJECT FILE FOR JJB INPUT & ENTER FUNCTIONS) JJBTCDOL.OBJ (TURBO C OBJECT FILE FOR JJB INPUT DOLLAR FUNCTIONS ) JJBSHOW1.C (TURBO C AND QUICK C SAMPLE PROGRAM ) JJBSHOW2.C (TURBO C AND QUICK C SAMPLE PROGRAM ) JJBSHOW3.C (TURBO C AND QUICK C SAMPLE PROGRAM ) JJBSHOW4.C (TURBO C AND QUICK C SAMPLE PROGRAM ) JJBSHOW5.C (TURBO C AND QUICK C SAMPLE PROGRAM ) JJBQCS1.BAT (QUICK C .BAT FILE TO LOAD JJBSHOW1 WITH JJB.QLB ) JJBQCS2.BAT (QUICK C .BAT FILE TO LOAD JJBSHOW2 WITH JJB.QLB ) JJBQCS3.BAT (QUICK C .BAT FILE TO LOAD JJBSHOW3 WITH JJB.QLB ) JJBQCS4.BAT (QUICK C .BAT FILE TO LOAD JJBSHOW4 WITH JJB.QLB ) JJBQCS5.BAT (QUICK C .BAT FILE TO LOAD JJBSHOW5 WITH JJB.QLB ) JJB-READ.DOC The main documentation file for JJB. JJB-FORM.DOC This is the JJB registration form file. From DOS, you can print it by entering: TYPE JJB-FORM.DOC > PRN: JJBFILES.BAT A list of all JJB files. JJBINSTL.BAT Explains how to install JJB. It is included in JJB-READ.DOC JJBPRINT.BAT Use this bat file to print all JJB files which have documentation. JJB.EXE JJBSHOW5.EXE These are demo files. It is hard to demo a programming environment and it probably should not be done; but I wanted to include something to show you what JJB can do. The source for JJBSHOW5.EXE is in file JJBSHOW5.C. Both of these were compiled with Quick C. If compiled with Turbo C they would run a lot faster. JJBKBD.H JJBSET.H In every program you write with JJB, you should include these two files as shown below: #include <jjbkbd.h> #include <jjbset.h> The JJB installation .bat files will move them to the \include directory for you when you do a learning or final installation. JJBQC-LI.BAT This file installs the learning installation for Quick C programmers. See the section in this file entitled 'QUICK C LEARNING INSTALLATION'. JJBQC-FI.BAT This file installs the learning installation for Quick C programmers. See the section in this file entitled 'QUICK C FINAL INSTALLATION'. JJBTC-LI.BAT This file installs the learning installation for Turbo C programmers. See the section in this file entitled 'TURBO C LEARNING INSTALLATION'. JJBTC-FI.BAT This file installs the learning installation for Turbo C programmers. See the section in this file entitled 'TURBO C FINAL INSTALLATION'. JJBREMOV.BAT Use this .bat file to remove all JJB files from drive c: and do a reverse installation. JJBQC.OBJ This is the main JJB 1.2 object file. The code is very tight and it was compiled with Quick C using only two include files: 'dos.h' and 'setjmp.h'. The same source file was used for both Quick C and Turbo C, however they were compiled separately to ensure that you do not have any problems with compatibility. JJBTC.OBJ This is the main JJB 1.2 object file. The code is very tight and it was compiled with Turbo C using only two include files: 'dos.h' and 'setjmp.h'. The same source file was used for both Quick C and Turbo C, however they were compiled separately to ensure that you do not have any problems with compatibility. JJBQCINP.OBJ JJBTCINP.OBJ These are the object files for the JJB 'input(' and 'enter(' functions. The same source file was used for both Quick C and Turbo C, however they were compiled separately to ensure that you do not have problems of compatibility. You will receive the complete source code along with comments when you register with JJB. JJBQCDOL.OBJ JJBTCDOL.OBJ These are the object files the JJB 'input_dollar(' and 'enter_dollar(' functions. The same source file was used for both Quick C and Turbo C, however they were compiled separately to ensure that you do not have problems of compatibility. You will receive the complete source code along with comments when you register with JJB. JJBSHOW1.C JJBSHOW2.C JJBSHOW3.C JJBSHOW4.C JJBSHOW5.C These are sample source files for both Turbo C and Quick C. In Turbo C you can just load them like any other source file after you install JJB. In Quick C, you should include the JJB Quick Library file JJB.QLB (qc /l JJB.QLB jjbshow.c) when loading or you can use the .bat files below designed only for Quick C loading of JJBSHOW files. JJBQCS1.BAT JJBQCS2.BAT JJBQCS3.BAT JJBQCS4.BAT JJBQCS5.BAT To load the source file JJBSHOW1.C in Quick C, enter the following from DOS: JJBQCS1. Do the same for the other show files. QUICK C ====================================================================== *** JJB LEARNING INSTALLATION FOR QUICK C PROGRAMMERS *** ====================================================================== Place the floppy diskette in drive a: and enter: JJBQC-LI It will: 1. Move all files to the hard disk drive c: jjbkey.h and jjbset.h to c:\include All the rest to c:\bin 2. Creates the JJB quick library JJB.QLB and load the first show file with JJBQCS1. You may have noticed that JJB tried to delete two files which it could not find on the disk drive. That is the way it should work because Quick C does not like to make a quick library if the file already exists on the disk drive. You should now be in Quick C looking at the sample file JJBSHOW1.C. If you now press 'F5', the file should compile and execute. If you need to exit Quick C, press 'ALT,' 'RETURN', 'X'. To re-enter the source file, from DOS enter 'JJBQCS1'. To compile and execute 'JJBSHOW1.C' from DOS enter: C:\BIN>JJBQCS1, then press 'F5'. You can load any of the five source examples with the following commands from DOS: JJBQCS1 JJBQCS2 JJBQCS3 JJBQCS4 JJBQCS5 To remove all JJB files from drive c: enter: 'JJBREMOV' This deletes all the JJB files from drive c: doing a reverse installation. QUICK C ====================================================================== *** JJB FINAL INSTALLATION FOR QUICK C PROGRAMMERS *** ====================================================================== The purpose of this installation is to install only the JJB files which are necessary for Quick C programming. The files are: JJBKBD.H JJBSET.H JJBQC.OBJ JJBQCINP.OBJ JJBQCDOL.OBJ Place the JJB diskette in drive a: and enter: 'JJBQC-FI' Don't forget to delete all JJB files from your hard disk before you make the final installation. The entire purpose of the final installation is to clean up your hard disk. So please remove the files as shown in the learning installation. TURBO C ====================================================================== *** JJB LEARNING INSTALLATION FOR TURBO C PROGRAMMERS *** ====================================================================== Place the floppy diskette in drive a: and enter: JJBTC-LI It will: 1. Move all files to the hard disk drive c: jjbkey.h and jjbset.h to c:\tc\include All the rest to c:\tc 2. Add the object modules to the small library and load the first show file JJBSHOW1.C You should now be in Turbo C and can execute the show file by pressing CTRL F9. To remove all JJB files from drive c: enter: 'JJBREMOV' This deletes all the JJB files from drive c: doing a reverse installation. TURBO C ====================================================================== *** JJB FINAL INSTALLATION FOR TURBO C PROGRAMMERS *** ====================================================================== The purpose of this installation is to install only the JJB files which are necessary for Quick C programming. The files are: JJBKBD.H JJBSET.H JJBTC.OBJ JJBTCINP.OBJ JJBTCDOL.OBJ Place the JJB diskette in drive a: and enter: 'JJBTC-FI' Don't forget to delete all JJB files from your hard disk before you make the final installation. The entire purpose of the final installation is to clean up your hard disk.

Example: if ( between(x,1,12) ) dosomething(); --------------------------------------------------------------------- void bright(void) bright( --------------------------------------------------------------------- The bright() function turns on the bright bit for for 'vf' functions. Example: bright(); vfs("This will be brighter. "); normal(); vfs("This will appear in the normal color."); The bright() function turns on the bright bit for the video attribute currently being used. It handles for both monochrome and color monitors. To turn it off use the normal() function or any other function which changes the video attribute. --------------------------------------------------------------------- void cf(void) cf( --------------------------------------------------------------------- The 'cf()' function is used by jjb_initalize() to initalize each option with a null copyright function. In jjb_setup() you can set up options without assigning functions to them. The options that are not assigned will execute this function. --------------------------------------------------------------------- void clrkeys(void) clrkeys( --------------------------------------------------------------------- This function clears the eight variables which were sent when the last key was read from the keyboard. The variables are KE, KEU, KEE, KCODE, IKE, IKEU, IKEE, IKCODE as explained in file: JJBKBD.H. --------------------------------------------------------------------- void default_opt(void) default_opt( --------------------------------------------------------------------- This function allows you to assign any option as the default option. Place it after the 'option(' function in jjb_setup(). If you assign more than one option as the default option, JJB will only use the last one assigned. It is nice to to be able to immediately start testing the function you are programming. As you are writing your program, place this function after the option you want to test. Execution will start with the option. Use this function only in jjb_setup(). For examples see source files JJBSHOW1.C through JJBSHOW5.C. --------------------------------------------------------------------- void dosexi(void) dosexi( --------------------------------------------------------------------- This is the function JJB executes when you press ALT X to exit your program. You can disable it in jjb_setup() by setting the following switch to true as such: set(ALTXOFF_SW,T); Once disabled, ALT X will not exit your program. Most program ask a question before exiting. You can activate the question by setting this switch in jjb_setup(): set(ALTXSURE_SW,T); Pressing ALT X should then show the following question in the bottom left-hand corner of the screen: 'DOS exit. Are you sure Y/N ?' Press 'Y' for yes to exit and 'N' for no, do not exit but return to the function you were executing. --------------------------------------------------------------------- void dosexit(*funcptr) dosexit( --------------------------------------------------------------------- If you have a function you want executed when leaving the program use this function to assign it in jjb_setup(). Here is an example: my_exit() { any code here } jjb_setup() { dosexit(my_exit); } --------------------------------------------------------------------- void funct(*funcptr) funct( --------------------------------------------------------------------- Every option you set up in jjb_setup() should eventually be assigned a function. Use 'funct(' to assign. All options are initalized by jjb_initalize() with the null function 'vff()' displaying the JJB copyright notice. Use this function only in jjb_setup(). For examples see source files JJBSHOW1.C through JJBSHOW5.C. --------------------------------------------------------------------- int getcoff(void) getcoff( --------------------------------------------------------------------- 'getcoff' is short for GET CURSOR OFFSET. The offset returned will be an integer from 0 to 1999. This is a very useful function when you want to save the cursor position and then reset it later. Here is an example of saving and resetting the cursor position: int save_cursor; 1 save_cusror = getcoff(); /* save physical cursor */ ` any code here setcoff(save_cursor); /* reset physical cursor */ In JJB there is an actual cursor seen on the screen and an invisible 'vf' cursor for all the video fast functions. This function affects only the actual phyicsal cursor. --------------------------------------------------------------------- int getvoff(void) getvoff( --------------------------------------------------------------------- This function returns the video offset position used by the JJB functions. The number returned will be a number from 0-1999. Here is an example of saving and resetting the video offset: int voffset; voffset = getvoff(); /* save invisible 'vf' cursor */ place any code here setvoff(voffset); /* restire 'vf' invisible cursor */ --------------------------------------------------------------------- unsigned char get_c(type) get_c( --------------------------------------------------------------------- This is a low-level keyboard function used JJB routines. It is explained in the complete printed documentation. --------------------------------------------------------------------- unsigned char get_any(void) get_any( --------------------------------------------------------------------- This function waits for you to press down on any key on the keyboard. It is unlike 'get_ch()' which will not return if you only press the capital locks or shift keys. Example: char ch; ch = get_any(); if (RIGHTSHIFT_PRESSED) do_something(); Once more thing. JJB is designed so that you do not have to worry about the character you just fetched from the keyboard. In the above example, you could use 'get_any();' instead of 'ch = get_any();'. --------------------------------------------------------------------- unsigned char get_ch(void) get_ch( --------------------------------------------------------------------- This is the main keyboard function you should use in your programs. Do not use getch() unless you want to bypass the JJB environment. The 'get_ch()' function is a very high-level function. It can read internally stored strings which you have defined with 'store_keys('. It can handle changing of options. In fact, it uses five lower-level functions in the following order: get_c(, keypress(, keyp(, kbint(, and read_kcode(. --------------------------------------------------------------------- unsigned char get_num(void) get_num( --------------------------------------------------------------------- This function is the same as 'get_ch()' except it will not accept alpha-numeric keypresses. --------------------------------------------------------------------- unsigned int get(int) get( --------------------------------------------------------------------- This function returns the value of an integer which has been stored in the integer array. Instead of having 50 to 100 separate integers. JJB uses only one array which can easily be set or accessed from any object module. See header file jjbset.h for a list of all the elements in the array. The complete printed documentataion explains each element in the array. --------------------------------------------------------------------- unsigned char getc(int) getc( --------------------------------------------------------------------- This function is the same as 'get(' except it gets a character from the JJB character array. Many examples are show in file jjbset.h --------------------------------------------------------------------- int gop(void) gop( --------------------------------------------------------------------- This function returns the current option number. Every option in your program is assigned a number starting with 1. If you have 50 options, then this function can return a number up to 50. See the help( function for examples. --------------------------------------------------------------------- void gname_out(void) gname_out( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void group(char *string) group( --------------------------------------------------------------------- This function defines a group by assigning it a character description. It also starts the assignment of options to the group. See the show files for many examples. --------------------------------------------------------------------- void group_heading(void) group_heading( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void help(*funcptr) help( --------------------------------------------------------------------- You can assign a help function which can be called in your program by pressing the F1 key. Here in an example: my_help() { if (gop() == 1) { do help for option 1 } if (gop() == 2) { do help for option 2 } if (gop() == 3) { do help for option 3 } if (gop() == 4) { do help for option 4 } if (gop() == 5) { do help for option 5 } } jjb_setup() { help(my_help); } --------------------------------------------------------------------- void init(*functpr) init( --------------------------------------------------------------------- Every group and option may be initialized with a function. There are many examples in the show files. --------------------------------------------------------------------- void jbot(void) jbot( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void jdelay(int) jdelay( --------------------------------------------------------------------- This is the JJB delay function. It does two loops, one inside the another. The number sent it must be from 1 to 255. If not, JJB will correct it. jdelay(1) does no delay. jdelay(2) loops 4 times (2 x 2) jdelay(5) loops 25 times (5 x 5) jdelay(100) loops 10,000 times (100 x 100) jdelay(255) loops 65,250 times (255 x 255) It is a simple little delay routine which does not take much thought to operate. Once you set the delay, it can continue with the same delay as follows: delay(80); delay(SAME); delay(SAME); delay(SAME); One more thing. JJB has the ability to read keys from a stored string. If not slowed down, they will appear on the screen as if they are being typed in. In order to slow them down every 'get_ch()' executes a delay depending on the value KBDDEL. The fastest setting is set(KBDDEL,1); The slowest setting is set(KBDDEL,255); Try this code and see what happens: store_keys("My name is John.!"); set(KBDDEL,88); input(30); The function 'input(30)' reads a string up to 30 characters in length returning the address. In the above example we don't need the address so it was ignored. The'!' character stands for the 'RETURN' key telling the input function that return has been pressed. The source code for all input and enter functions is available only for registered users. --------------------------------------------------------------------- void jjb_initalize(void) jjb_initalize( --------------------------------------------------------------------- This function initalizes JJB direct memory access address, the arrays and pointer, sets up the default color settings for the video mode in use, plus many other things. See the main() function in this glossary and the show files for more explanation. --------------------------------------------------------------------- void jjb_setup(void) jjb_setup( --------------------------------------------------------------------- Use this function to set up groups of options which JJB will execute when it executes the function jjb_start(). For examples, see source files JJBSHOW1.C through JJBSHOW5.C. --------------------------------------------------------------------- void jjb_start(void) jjb_start( --------------------------------------------------------------------- This function is a processing loop which executes your program functions. Whenever you select a new option, JJB does a long jump back to this loop executing the leave functions for the option and group, then it initalizes the new group and option and finally calls the option function. This loop will be continued until you press ALT X to exit your program. If you are testing your program you can press CONTROL C or CONTROL PAUSE to force an abort returning to QUICK C or TURBO C. Further down in this file is a box which outlines the processing loop that that function begins executing. --------------------------------------------------------------------- void jsel(void) jsel( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void kbint(void) kbint( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void keyp(int type) keyp( --------------------------------------------------------------------- This is a low-level function used JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void keypress(int type) keypress( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void leave(*funcptr) leave( --------------------------------------------------------------------- Every group and/or option can be exited with a function. There are many examples of this in the show files. --------------------------------------------------------------------- loc(int row, int col) loc( --------------------------------------------------------------------- Use this function to locate the physical cursor on the video monitor. 'loc(1,1);' places the cursor in the top left-hard corner of the screen. 'loc(25,80);' places the cursor in the bottom right-and corner. You can also use the function 'setcoff(' to position the physical cursor as in the following examples: setcoff(0) is the same as loc(1,1) setcoff(1999) is the same as loc(25,80) --------------------------------------------------------------------- void main(void) main( --------------------------------------------------------------------- This is the main function in your program. Every program you write using JJB should have a main function which looks like this: main() { jjb_initalize(); /* initalize JJB system */ jjb_setup(); /* set up your program options */ jjb_start(); /* start executing your program functions*/ } You do not have to use all of the features of JJB. If you just want to use some of the JJB functions, initalize JJB by making it your first instruction in main. After initalization, you can use almost all of the functions explained in this glossary. main() { jjb_initalize(); place your program code here } --------------------------------------------------------------------- int nbetween(x, from, to) nbetween( --------------------------------------------------------------------- int x; integer testing int from; from range int to; to range This function returns a true condition if integer x is not equal to or fall between the from/to range. Example: if ( nbetween(x,1,12) ) dosomething(); --------------------------------------------------------------------- void nf(void) nf( --------------------------------------------------------------------- Each group and option can be initalized and exited with a function you can assign in jjb_setup(). If you do not assign one, JJB will execute this null function which does nothing. --------------------------------------------------------------------- void normal(void) normal( --------------------------------------------------------------------- Use 'normal()' in your program when you want to change the attribute to the normal color. This function properly handles both color and monochrome monitors. This function resets the video fast 'vf' color attribute to the normal color attribute. On monochrome it is white on black (7). The normal color attribute is set in jjb_initalize() as followed: set(VNCOLOR, WHITE ONBLUE). It can be changed in jjb_setup() to any color on any color as follows: set(VNCOLOR, BLACK ONBLUE); The JJB manual devotes an entire chapter on how easy it is to select a color setting. --------------------------------------------------------------------- void option(char *,DRAWLINE) option( --------------------------------------------------------------------- The option function starts defining a new option by assigning it a string of characters. examples: jjb_setup() { option("Copy File") option("Read 'F'ile",DRAWLINE); option("Write File F8") } In the first example above, we did not specify which letter to use for selection so JJB will use the first letter. If the first letter was used by a previous option, then JJB will use the second letter and so on. In the second example we specified 'F' to be the selection letter. You can assign to any option the function keys F2 thru F9 by just placing it in the description at the end. Notice that the ',DRAWLINE' is optional and should be used only when you what to separate this option from the next one. After 'option(' you can use 'funct(', 'init(', 'leave(', default_opt(' in any order. --------------------------------------------------------------------- char *pak(void) pak( --------------------------------------------------------------------- The 'pak()' function returns the global address of "Press any key ". The following will video it on the screen and wait for a keypress: vfs( pak() ); get_ch(); It is the same as: char ch; printf("Press any key "); ch = getch(); --------------------------------------------------------------------- void read_kcode(void) read_kcode( --------------------------------------------------------------------- This is a low-level function used by the JJB routines. It is explained in detail in the complete printed documentation. --------------------------------------------------------------------- void reverse(void) reverse( --------------------------------------------------------------------- Use 'reverse()' in your program when you want to change the attribute to the reverse color. This function properly handles both color and monochrome monitors. This function resets the video fast 'vf' color attribute to the reverse color attribute. On monochrome it is black on white (112). The reverse color attribute is set in jjb_initalize() as followed: set(VRCOLOR, BLUE ONWHITE). It can be changed in jjb_setup() to any color on any color as follows: set(VRCOLOR, RED ONWHITE); --------------------------------------------------------------------- void set(int offset, int value) set( --------------------------------------------------------------------- This function sets the value of an integer which has been stored in the JJB integer array. Instead of having 50 to 100 separate integers to handle JJB, it uses only one integer array which can easily be set or accessed from any object module. See jjbset.h file for a list of the elements in the array. The complete printed documentataion explains each element in the array and what it does. --------------------------------------------------------------------- void set_color(unsigned int color) set_color( --------------------------------------------------------------------- This is a high-level function which allows you to change the color setting. Examples: set_color(BLACK ONRED); set_color(BLUE ONWHITE); You can set the color to any color on any color. When your program runs, if the user of your program has a monochrome, then the change will not be made. --------------------------------------------------------------------- void setcoff(int) setcoff( --------------------------------------------------------------------- 'setcoff' is short for SET CURSOR OFFSET. Use this function to set the physical cursor anywhere on the screen. It does the same as the 'loc(' function except it uses only one integer amount for the offset instead of a row and a column. The number you send it must be between 0 and 1999. setcoff(82) will place the cursor on row 2, column 3. Here is an example of saving and resetting the cursor position: int save_cursor; save_cusror = getcoff(); ` any code here setcoff(save_cursor); --------------------------------------------------------------------- void setvoff(int) setvoff( --------------------------------------------------------------------- This function sets the video fast 'vf' invisible video offset cursor. It should always be a number from 0 to 1999. Here is an example of saving and resetting the video offset: int voffset; voffset = getvoff(); /* save video offset */ any code here setvoff(voffset); /* reset video offset */ The video offset can also be set with the 'vloc(' function. Both do the same thing except 'setvoff(' does it with only one integer and is much faster because there is no calculation to make. --------------------------------------------------------------------- void store_key(char *pointer) store_keys( --------------------------------------------------------------------- The 'store_keys(' function allows you to internally store a string of characters to be read as keypresses with the get_ch(), input( and enter( functions. Example: store_keys("Your program typed this in.!"); Once you have stored the characters using this function, nothing will happen until execution comes to the next get_ch(), get_num(), get_any(), or any of the input or enter functions. When that happens, the actual keyboard will not be read. Instead the character will be fetched from the string. You can adjust the speed at which characters are read by setting the KBDDEL variable as follows: 'set(KBDDEL,88);'. The get_ch() function does a delay with every read just for the purpose of slowing down internally stored strings. KBDDEL is usually set to '1' so there is no delay unless you reset it. You can place special characters in the string which have the following meaning: '%' is ALT '!' is RETURN '@' is ESC '<' is LEFT ARROW '>' is RIGHT ARROW '^' is UP ARROW '~' is DOWN ARROW The JJB demo does a 'store_keys("%!>>>>>>>>>@");' to show you some fast windowing. --------------------------------------------------------------------- void strcopy(char *pointer, char *pointer) strcopy( --------------------------------------------------------------------- This function does a simple string copy. An example is: char string[30]; char *sp; sp = &string[0]; strcopy("Copy this", &string[0]; strcopy("Copy this",sp); --------------------------------------------------------------------- void va(unsigned int color) va( --------------------------------------------------------------------- This is the lowest-level function for setting the color. Here is an example: va(RED ONBLACK); It does not take into consideration monochrome like the 'set_color(' function does. Use it only when you know the monitor your program will be displayed on. It does 'exactly' the same thing as: set(VATTRIB, RED ONBLACK)G. --------------------------------------------------------------------- int vbl(void) vbl( --------------------------------------------------------------------- This function returns the video fast 'vf' invisible offset for the beginning of the row you are on. It will be an integer from 0-1999. Example: int beg_line; beg_line = vbl(); --------------------------------------------------------------------- void vfbout(char) vbout( --------------------------------------------------------------------- This does a video fast 'vf' of the bits of one byte. vfbout(9); puts out: 0000 1001 --------------------------------------------------------------------- void vch(char ch, int voffset) vch( --------------------------------------------------------------------- This is a low-level video fast 'vf' function which puts on the screen one character at the invisible offset position: Here is an example: char ch; ch = 'A'; for (x=70; x<=159; x++) { vch(ch, x); } The above will put 80 characters on the screen. Ten characters will appear on row one, and 70 characters will appear on row two. --------------------------------------------------------------------- void vclr_screen(void) vclr_screen( --------------------------------------------------------------------- This is a video fast 'vf' function which clears the screen and places the 'vf' invisible cursor in the home position. --------------------------------------------------------------------- void vclreol(void) vclreol( --------------------------------------------------------------------- This function will clear to end of a line starting at the video fast 'vf' offset position. It clears to the end of the row from the present invisible 'vf' cursor. --------------------------------------------------------------------- void vclrft(int from, int to) vclrft( --------------------------------------------------------------------- This function clears the screen from one row to another. Example: vclrft(2,24); The above example clears rows 2 through 24, leaving row 1 and row 25 on the screen. --------------------------------------------------------------------- void vclrw(void) vclrw( --------------------------------------------------------------------- This function clears the main JJB window. If you do not want a window to appear, set the following switch in jjb_setup(): set(VCLRW_SW,T). Once set, vclrw() function will clear rows 2 through 24 not making a window. --------------------------------------------------------------------- void vcr(void) vcr( --------------------------------------------------------------------- This function videos fast 'vf' a carriage return. It is the 'vf' equivalent of 'printf("\n");'. --------------------------------------------------------------------- void vcrs(int x) vcrs( --------------------------------------------------------------------- This videos fast 'vf' x number of carriage returns. --------------------------------------------------------------------- void vf_window(row,column,depth,width) vf_window( --------------------------------------------------------------------- This function videos fast 'vf' a window at integer row, column, depth, and width. Example: vf_window(8,20,10,50); You can use the set_color(COLOR ONCOLOR) before using this function to make any color window you choose. --------------------------------------------------------------------- void vfc(char) vfc( --------------------------------------------------------------------- Use this function to video fast 'vf' a character on the screen. Here is an example: char ch; ch = get_ch(); vfc(ch); --------------------------------------------------------------------- void vfcc(char) vfcc( --------------------------------------------------------------------- Use this function to video fast a character on the screen placing the physical cursor after it. Here is an example: char ch; ch = get_ch(); vfcc(ch); If you have the source code for the JJB input routines then you can see that this function was used to display each character as it was typed in. --------------------------------------------------------------------- void vfi(int number) vfi( --------------------------------------------------------------------- This function videos fast 'vf' an integer on the screen. Examples: vfi(1200); vfi(x); --------------------------------------------------------------------- void vfir(int number, int fieldlength) vfir( --------------------------------------------------------------------- Use this function to video fast 'vf' an integer in a field, right-justified. Examples: vfir(x,5); vfir(123,5); This might be on another subject, but one nice thing about the input routines is that in addition to editing the numbers input, they also return the number right-justified in a field ready to be displayed on the monitor. In that case you do not need to use this function. --------------------------------------------------------------------- void vfs(char *pointer) vfs( --------------------------------------------------------------------- This function videos fast 'vf' a string at the invisible cursor position. Examples: char string[40]; char *sp; sp = &string[0]; vfs("Put out this string."); vfs(sp); vfs(&string[0]); --------------------------------------------------------------------- void vfsc(char *pointer) vfsc( --------------------------------------------------------------------- This function is the same as 'vfs(' except it puts the physical cursor on the screen after putting out the string. Normally, the 'vf' function advances the video offset so your strings and integers are not all placed in the same location. They do not normally place the physical cursor because then they would not be fast. This function videos fast the string and then places the actual physical cursor at the end. --------------------------------------------------------------------- void vfsdo(char *ptr,int down,int over) vfsdo( --------------------------------------------------------------------- The 'vfsdo(' function, videos fast 'vf' a string of chararacter and then comes down and over on the screen. Once set, you may use ',SAME' to duplicate the previous functions. vloc(6,20); vfsdo("Put this on screen.',2,20); vfsdo("This appears on row 8 starting at column 20",SAME); vfsdo("This appears on row 10 starting at column 20",1,20); vfsdo("This appears on row 11 starting at column 20",SAME); vfs("Press any key "); get_ch(); --------------------------------------------------------------------- void vfsl( char *pointer, int fieldlength) vfsl( --------------------------------------------------------------------- This function videos fast 'vf' a string left justifing it in a field. It is a very useful function when you do not know how many characters will be put out. Example: vfsl("Put 6 blanks after this.",30); The above string is only 24 characters in length. The required field length is 30, so 6 blanks will be put out after the string. --------------------------------------------------------------------- void vftout(char,int x) vftout( --------------------------------------------------------------------- 'vftout(' stands for video fast times out. It does a super fast character out x number of times. Example: vloc(10,1); /* locate 'vf' at row 10 column 1 */ vftout('-',80); /* put out 80 hyphens */ The above example places a line on the screen at row 10 at extremely high speed. --------------------------------------------------------------------- void vfw(row,col,width,depth) vfw( --------------------------------------------------------------------- The 'vfw(' function makes a video fast 'vf' window on the screen. Example: set_color(RED ONBLUE); vfw(8,16,50,10); normal(); The above example makes a window with a blue background at row 8, column 16, width of 50, and depth of 10 rows. The color attribute was then set back to the normal color. --------------------------------------------------------------------- void vgrid(void) vgrid( --------------------------------------------------------------------- This function places a border around the screen. You can use it to help determine rows and columns. JJB is designed so that if you press CONTROL G whenever your program is expecting a keypress, JJB will place this programmer's grid on the screen. --------------------------------------------------------------------- void vloc(int row, int column) vloc( --------------------------------------------------------------------- This function sets the video fast 'vf' invisible cursor. Row must be an integer from 1 to 25. Column must be an integer from 1 to 80. You can access this value with the 'getvoff()' function as a number from 0 to 1999. The 'setvoff(' function is the same as 'vloc(' except it requires only one number 0-1999 to set the 'vf' invisible cursor. 'vloc(1,1)' sets the 'vf' offset to the top left hand corner. 'vloc(25,80)' set the 'vf' offset to the bottom right hand corner. 'vloc(1,1) is exactly the same as setvoff(0). --------------------------------------------------------------------- char vr(int voffset) vr( --------------------------------------------------------------------- This function reads a character with color attribute from the video monitor returning it to you. --------------------------------------------------------------------- unsigned char vrc(int voffset) vrc( --------------------------------------------------------------------- This function reads one character from the JJB save screen array, and places it on the screen with its attribute. The function 'vsave_screen()' stores the entire screen in the array. With the 'vrc(' function you can fetch a character from the array and place it back on the screen. This function was used in the JJB demo to slide the window across the screen very smoothly. --------------------------------------------------------------------- void vrest_scr(int array address) vrest_scr( --------------------------------------------------------------------- This function restores a screen from an array. See the 'vsave_scr(' function for examples. --------------------------------------------------------------------- void vrest_screen() vrest_screen( --------------------------------------------------------------------- This function restores the screen from the JJB integer array. Use it after the vsave_screen() function to restore the screen. --------------------------------------------------------------------- void vsave_scr(int array address) vsave_scr( --------------------------------------------------------------------- This function allows you to save a screen. It can be used to save as many screens as you need. Below is an example of how to use it to simultaneously save and restore two screens. any_function() { int screen1[2000]; /* integer array for a screen */ int screen2[2000]; /* integer array for a screen */ vsave_scr(&screen1[0]; /* save screen 1 */ clr_screen(); /* clear the screen */ vloc(1,1); /* home the 'vf' cursor */ vfs("First message"); /* put text on screen */ vsave_scr(&screen1[0]); /* save screen 1 */ vloc(1,1); /* home the 'vf' cursor */ vfs("Second message"); /* put text on screen */ vsave_scr(&screen1[0]); /* save screen 2 */ vrest_scr(&screen1[0]; /* restore screen 1 */ get_ch(); /* stop to pause */ vrest_scr(&screen2[0]; /* restore screen 2 */ } There is no limit to the number of screens you can save and restore with this function. --------------------------------------------------------------------- void vsave_screen(void) vsave_screen( --------------------------------------------------------------------- This function saves the screen in the JJB integer array. It is used by JJB to save the screen before doing the pull-down menus. The screen can be restored with 'vrest_screen();'. --------------------------------------------------------------------- void vspace(void) vspace( --------------------------------------------------------------------- This function is the video fast 'vf' equivalent of printf(" "). --------------------------------------------------------------------- void vspaces(int x) vspaces( --------------------------------------------------------------------- This function videos fast 'vf' x number of spaces on the screen. --------------------------------------------------------------------- void underline(void) underline( --------------------------------------------------------------------- Use 'underline()' in your program when you want to change the color attribute to the underline color. This function properly handles both color and monochrome displays. This function resets the 'vf' color attribute to the underline color attribute. On monochrome it is '_' (1). The reverse color attribute is set in jjb_initalize() as followed: set(VRCOLOR, BLUE ONWHITE). It can be changed in jjb_setup() as in this example: set(VRCOLOR, RED ONWHITE); --------------------------------------------------------------------- char upcase(char) upcase( --------------------------------------------------------------------- This function returns the upper case of the character sent to it. ****************************************************************************** * * * Functions in file: * * * * ( Note 1 ) ( Note 1 ) * * * * JJBQC.OBJ & JJBQCINP.OBJ & JJBQCDOL.OBJ & * * JJBTC.OBJ JJBTCINP.OBJ JJBTCDOL.OBJ * * --------------- --------------------- ------------------- * * * * jjb_initalize() input( input_dollar( * * jjb_start() input_num( enter_dollar( * * group( input_lnum) * * option( enter( * * init( enter_num( * * leave( enter_lnum( * * help( Plus additional functions * * default_opt() you can use to make * * dosexit( your own input and * * plus the other enter functions * * functions listed * * above * * * * Note 1: The complete source for these object modules will be sent to * * users who register with JJB. * * * ****************************************************************************** ****************************************************************************** * * * jjb_start() * * * * This function, in its simplest form, is a continuous loop. * * * * * * while (1) { * * * * execute the function initalizing the group, if any. * * * * execute the function initalizing the option, if any. * * * * -------> execute the function for the option. * * (long jump to here when changing options. * * execute the function leaving the option, if any. * * * * execute the funtion leaving the group, if any. * * * * } * * * * Changing options does a long jump back to this loop finishing up the * * option and group and starting a new one. * * * ****************************************************************************** ****************************************************************************** * * * Functions you may use in jjb_setup(): * * * * group( Start a new group of option & assign group description. * * * * option( Define the next option by assigning a description * * * * funct( Assign a function name to an option. * * * * init( Assign a function name to initalize group or option. * * * * leave( Assign a function name to exit a group or option. * * * * default_opt( Tag this option as the default option. * * * * help( Assign a function name for F1 help key. * * * * dosexit( Assign function be be executed when exiting to DOS. * * * * set( Change variable or switch setting in the integer array * * * ****************************************************************************** ****************************************************************************** * * * char * input(int length) * * char * input_num(int length, int from, int to) * * char * input_lnum(int length, long from, long to) * * char * input_dollar() * * * * These are high-level programming functions.
