It fully supports either a mouse or keyboard entry and will work on any IBM PC/PC- XT, AT or compatible computer with MS-DOS 2.11 or newer. Roadways is distributed as Shareware and as such is free to be copied, passed on and uploaded to any computer service or bulletin board. After a trial period, it is expected that the user will register his or her copy if it is going to continue to be used. Registration has many advantages. You will not only be assured of having the most up-to-date copy of Roadways PC, you will also get free technical support and a subscription to the Roadways Times, a newsletter produced just for the registered users of Roadways PC. Also you will be able to by-pass the opening copyright screen as well as having access to the Roadways PC support conference on the Missing Link BBS. If you have a modem, you may get the latest news and version of Roadways PC as well as technical help by calling the Missing Link bulletin board at (618)233-6982, 1200 to 9600 baud, 8 bits, No parity and 1 stop bit (i.e. - 2400, N, 8, 1), and [J]oin the Roadways conference, number 5. Whenever any new datafiles, suggestions or hints come in from other registered users, they too will be posted here for other Roadways PC users to use. To register your copy, see the registration form at the end of this documentation. SYSTEM REQUIREMENTS Here are the requirements for running Roadways PC on your computer: An IBM PC/XT/AT/286/386/486 or compatible computer Minimum 384K of RAM Any type display (Monochrome, CGA, EGA, VGA, etc.) One Floppy Drive (any size or density) (Hard drive recommended) Microsoft or Logitech Compatible Mouse or Trackball (Optional) Printer (Optional) DISTRIBUTED FILES Your copy of Roadways PC should include the following files. If it does not, please contact the author with information about where your copy came from, so a good copy of Roadways can be sent to both you and your source. This will ensure everyone will have a complete copy of Roadways PC, with all of its features intact. ROADWAYS.EXE ----------- The main Roadways PC program file 1 ROADWAYS.DAT ----------- The text file containing the city data ROADWAYS.DOC ----------- This documentation file ROADWAYS.STA ----------- Data sorted by State ROADWAYS.CTY ----------- Data sorted by City ROADWAYS.TIM ----------- Data for the shortest time routes PRINTDOC.BAT ----------- Documentation Printer File INSTALL.EXE ----------- Roadways PC installation program README.DOC ------------- Special information not in the manual INSTALLING ROADWAYS PC ON YOUR COMPUTER Installing Roadways PC is very simple. You may install Roadways PC to either a floppy disk or to your hard disk if you have one. If you are upgrading from an earlier version, please go to page 15 and perform the procedures in the section entitled, UPGRADING ROADWAYS PC. If you try to run Roadways PC without first running the INSTALL program, Roadways will remind you. You will see a screen that informs you that Roadways PC has not been configured for your system. At this point, Roadways will end and you can run INSTALL to configure the program. To install Roadways PC, all you need to do is follow these instructions: 1. Insert the disk containing Roadways PC into your disk drive. 2. Type INSTALL and press <enter>. 3. You should now see a menu that gives you the option to do one of four things: 1 - Install or change installation of Roadways PC 2 - Register your copy of Roadways PC 3 - Run Roadways PC 4 - Exit this program Select option 1. 4. Next, you will be asked if you wish to make a backup of your Roadways PC program disk. If you answer Y to this question, you will be exited from INSTALL so you can use DISKCOPY to back up your original disk. If you answer N to this question, you will be allowed to continue with the installation procedure. 5. Next the question "Do you want to install Roadways now?" is asked. This is just to make sure you really do want to install Roadways, and is only to give you a chance to change your mind (although you really should go ahead and install it!). 6. Now you will be asked if you wish to install Roadways PC onto a Hard drive. If you answer Y to this question: 2 a. You will be asked if the subdirectory C:\ROADWAYS is where you want Roadways installed. If you want Roadways installed in a sudirectory on drive C: called ROADWAYS, type Y. b. You can enter a different drive and subdirectory if you want. Just enter the letter of the drive you want Roadways installed to, and when asked for the subdirectory name, type in any legal DOS name. c. The subdirectory will be created on the specified drive and Roadways will install (or copy) itself into that subdirectory. 7. The next question asks if you have a color monitor. If you have any type of color monitor and card, type Y. If you have a monochrome or Hercules display of any type, type N. If you typed N, you will be asked if you have a Hercules video adapter or display. Answer Y if you have a Hercules card, N if you don't. If you answer N to the Hercules question, and get either an error when you try to run Roadways or the screen stays blank, try re-running INSTALL and selecting Y for Hercules. 8. The next question asks if you want Roadways PC to calculate a mileage reimbursement cost per mile. This option is primarily designed for folks that get reimbursed for their mileage on business trips, although it has other uses as well, such as calculations for IRS mileage deductions and so forth. Please note, however, that the author of Roadways PC makes no claims as to the accuracy of the mileages calculated. Roadways PC is primarily a tool to help you plan your trip, and as such should not be used when accuracy is important. If you want Roadways PC to calculate a cost per mile, simply type 'Y'. Next you will be asked for the mileage rate. This is the amount per mile you want Roadways PC to use. You must enter this number as a decimal. For example, if you want to use 24 cents per mile as the rate, type .24 and hit <enter>. Don't worry if the amount you want to use changes later, as you can easily update it from within Roadways PC. 9. Next, you will need to choose the type of printer you have. Simply select your printer from the list. You will notice that this list is very general. This is because the options differ only in the characters that are printed from the trip route screen. If you have a dot matrix or laser printer, it is probably IBM compatible. You can tell by looking at the printout when you do a route. If you selected the IBM, laser or EPSON selections from the list, when you print out a route, you should see smooth, uninterrupted lines between the headings and the list of cities and routes. If you have a dot matrix printer and you get a bunch of letters instead of smooth lines, you will need to change your printer dip switches to the IBM character set if there is one on your printer. Otherwise, you'll have to choose option 5 (Other). 3 The same applies to other printers, if you see a bunch of letters across the page separating the headings and the list of cities. This indicates that you will need to select either option 4 or 5. This will use the '-' and the '=' instead of the extended characters. If you do not have a printer, it doesn't matter what you select, but you must select something! 10. The next questions are to establish the average speed you want used for calculating driving times. By default, Roadways will use 55 mph for roads with a 65 mph speed limit and 45 for all other roads. With this release of Roadways PC, changes were made to handle states with the lower 55 mph speed limit on interstates. As a result, the times for the eastern seaboard states are much more accurate. Just by way of explanation, the 55 and 45 mph averages were chosen as the defaults based on quite a few tests with several different users. Although most people are absolutely certain they average 70 mph in 65 mph areas, all but a VERY few actually average much over 60. If you have a family, 55 may be a little high on many trips, but most folks were surprised at how close these numbers came to their actual driving times. This option was added for those 'out-of-the-ordinary' folks that drive either faster or slower than the average person. To accept the default speeds of 55 and 45 mph, just hit <enter> to both of the questions. To enter your own speeds, simply type the numbers in. Decimals and letters are not allowed, only numbers, and the range can be from 0 up to ludicrous speed! 11. Now you need to choose the name of the city datafile Roadways PC will use. This is primarily for those folks that plan on using or creating datafiles for other countries or to cover, in detail, some particular area. For the first time user, I suggest just hitting <enter> since this will select the datafiles that came with your copy of Roadways PC. Please note that if you type in the name of a datafile that does not exist, Roadways PC WILL NOT RUN! You will have to re- run the INSTALL program to enter the name of an existing datafile. 12. Now, Roadways PC will create a file called ROADWAYS.CFG which will contain the configuration information for your computer. This file will be put in the subdirectory where you installed Roadways or on the floppy disk if you did not put it on a hard disk. << Note >> If you have configured Roadways PC for your computer, and wish to pass Roadways along to someone else, please do not copy the 4 ROADWAYS.CFG file onto their disk. Also, do not include it in an archive or zip file, as it may cause problems for the next person who gets the copy. The files that should be included are the ones listed above in the section entitled "DISTRIBUTED FILES". 13. Now the Installation program is complete. You will be returned to the main menu, and if you are a registered user, you will have the option to fully register your copy of Roadways PC. REGISTRATION If you are a registered user of Roadways, you may bypass the copyright screen that appears on bootup. If you are already at the INSTALL program main menu, skip to step 3. To configure your system to by-pass the copyright screen, follow these steps: 1. Insert your Roadways PC disk into your computer or go to the subdirectory on your hard drive that contains the Roadways PC program. 2. Type INSTALL <enter>. 3. You will be asked if you are installing Roadways on a Tandy 1000 RL, SL, TL, SL/2, TL/2 or TL/3. This option applies to any of the Tandy 1000 series of computers that have DOS in ROM. If you own one of these computers, ROADWAYS.EXE will be renamed RW.EXE, and you will be taken directly to step 5, and upon completion, a file called ROADWAYS.BAT will be put on the disk that contains your copy of Roadways. Please note that even if you are NOT a user of one of these computers, you may want to select this option since it will prevent any changes from being made to your AUTOEXEC.BAT file. Some folks prefer this. 4. When asked, enter the letter of the drive where you boot your computer. REGISTER will check that drive to see if an AUTOEXEC.BAT file exists. 5. You will be asked for the code that was in the registration letter that was sent to you by the author. Enter that code and hit <enter>. 6. If you have a Tandy, or chose the option in step 3, at this point the REGISTER program will end and the file ROADWAYS.BAT will be written to your disk. To run Roadways, type ROADWAYS and hit <enter>. If all has gone well, Roadways will run without the copyright screen. 7. IF you did not select the Tandy option, REGISTER will check your boot drive for an AUTOEXEC.BAT file. If one does not exist, you will be asked if you want to create one. If so, type Y . 5 8. A single command will be added to the beginning of your AUTOEXEC.BAT file. This command can be moved anywhere in the AUTOEXEC.BAT file you wish, as long as it gets executed before Roadways PC gets run. Please note that without the statement that REGISTER puts in the AUTOEXEC.BAT, you cannot bypass the copyright screen. 9. If all has gone well, you should be able to select option 3 from the main INSTALL menu and Roadways PC will start-up without the Copyright screen. USING ROADWAYS PC Roadways PC is designed to be simple to use. If you have a mouse that is 100% Microsoft compatible (i.e. - Microsoft, Logitech, Dexxa, etc.) and the driver is loaded, Roadways PC will detect that it is present and display a Mouse cursor whenever appropriate. Once you have Roadways PC properly configured, the program will load and run, presenting you with a copyright notice if you are not a registered user. To exit this screen, simply press any key or left mouse button or wait for about 5 seconds. At this point, Roadways PC will check to make sure you have all of the necessary data files and if not, it will attempt to create them. The most important file of all is the file ROADWAYS.DAT. Without this file, Roadways PC will not run. The other three data files, ROADWAYS.CTY, ROADWAYS.STA and ROADWAYS.TIM are created from the ROADWAYS.DAT file, so if they are missing, Roadways PC can still run. However, before it will work, it must create the missing files. If for some reason, any of the sorted data files is missing, Roadways PC will inform you of this and then it will proceed to create the files, save them and then run Roadways PC. This should be an almost automatic action requiring no input from you other than pressing a key to go on. During the creation of the datafiles, you will notice a small box on the bottom of center of the screen with an arrow inside that changes direction. This is just to let you know that something is going on and that your computer hasn't locked up. Once Roadways has loaded and made sure all of the required files are present, it will begin loading the city data in. You will see two lines in the lower portion of the screen that look like this: Counting to: City Number: The first line indicates the number of cities in the database. The second line will count up until it matches the first line. The purpose of this is just to let you know that something is going on, and that your computer hasn't locked up. When the two numbers match, you will be presented with a 6 choice of having the cities sorted either Alphabetically by city or Alphabetically by state. Press either 'C' or 'S' or use the mouse to click anywhere on the word 'City' or 'State'. Controlling Roadways PC with the Keyboard You should now be at the main program screen. Down the left side there should be a list of cities, arranged either by state or by city, depending on your choice earlier, with the top choice highlighted. At the bottom, you will see a block with two choices, labeled NEXT PAGE and PREVIOUS PAGE. This block is for the Mouse user only. It can, however, help you remember the proper keys to use. The first letter of each of the commands is highlighted. Pressing any of these keys will do what the function says. If you have a mouse, see the section on Controlling Roadways PC with a Mouse for more information on their use. Pressing any unassigned keys (say for instance the 'H' key) will cause the Key Help block to appear just above this Mouse block, and provides you with the functions of all of the keys that can be used at this point in the program. Toward the top, you will see a block with the prompt: Select Starting City You do this by using the following keys: Up Arrow Key --------------------- Move up the list Down Arrow Key ------------------- Move down the list PgUp key (or P key) -------------- Go to Previous Page PgDn key (or N key) -------------- Next Page Home key ------------------------- Go to the First Page End Key -------------------------- Go to the Last Page Enter Key ------------------------ Select a city ALT Key -------------------------- Activate the menu bar Q key ---------------------------- Quit Roadways PC R key ---------------------------- Retrieve saved routes M key ---------------------------- Change the Mileage Rate Any other key -------------------- Key help window If you have problems remembering what keys do what, just press a key that is not on this list ('H' for example), and you will be presented with a window that shows the primary key commands for Roadways PC. To clear the window, just press <enter>, space bar or ESC. Selecting a City To select a city, simply use the arrow keys to move the highlighted area over the city you want, then press <enter>. If you do not see the city you are looking for on the screen, press the PgUp (or P) or PgDn (or N) keys to flip through the 'pages' of cities until you locate the city you are looking for. Once you have selected a Starting City, you will notice that 7 the block at the top right now says: Select Ending City Also, you will see a block just below that block which now indicates what city you chose as the starting city, and is waiting for you to choose the ending city. Repeat the above procedure to select the ending or destination city, and again press <enter>. Now you will notice that the window that contains the starting city also displays the ending city along with a prompt for you to decide if these are correct. If so, type either 'Y' or press the <enter> key. If not, type 'N', and you will be able to re-select both the starting and ending cities. If the starting city and ending city are the same, Roadways PC will clear the block and tell you to select the starting city again. Once you type 'Y', you will see a small square toward the top of the screen that is labeled: Miles: You will see numbers count up, as Roadways PC calculates the total mileage to the destination. As before, this is put on the screen mostly to let you know something is happening, since on a slower computer, the route can take longer to complete although it is still more than 5 times faster than my closest competitor! This is especially true of long, coast-to-coast routes. Menu Bar Pressing and releasing the ALT key will toggle the menu bar at the top of the screen. From these menus you can perform many of the functions that are also available from the hot keys, such as retrieving saved routes and exiting Roadways PC. The options on the menu are as follows: File This option lets you retrieve saved routes from disk. You will be asked for the drive and directory name of the directory containing your Roadways PC route files. If you have saved the route files in the same directory and drive that has Roadways PC, all you have to do is press <enter> . If there are no route files in the default directory or the directory you specify, Roadways will tell you and give you the option of entering a different drive and directory or you can press 'R' to return to the main city selection screen. If there are files with an .RDW extension in the directory, you will see a directory of all these files on the screen, and a prompt asking which file you want to retrieve. Just type in the name of the route file (with or without the extender. It doesn't matter.) and press <enter>. You should now see the route just as you saved it. At this 8 point you may elect to do one of the following: PRINT - Print the route you just retrieved MORE - Retrieve another route RETURN TO ROADWAYS PC MAIN - Return to the City Selection screen Simply press the first letter of the option you want and do what Roadways PC tells you. Utilities Here you can change the mileage rate, default settings, choose a default starting city, re-run the last route or toggle using either the shortest time or shortest distance calculations. Help This brings up the same window as pressing an unassigned key (i.e. - H or F1). ROADWAYS PC This will bring up the introductory Copyright screen that registered users get to by-pass. This is just for your own informational purposes. Quit Allows you to quit Roadways PC. Shortest Distance (or Time) This is just a status indicator and cannot be selected. This is where you can tell if you have selected to have a route run on the shortest distance or the quickest time. For more information on the options in the Utilities section, see the next chapter. UTILITIES MENU The Utilities Menu contains many different options to allow you to customize your Roadways PC. Here are the functions of the different items on the menu: Mileage Rate Change This option is used to change the mileage rate used to calculate driving costs. Here you will have 4 options: 1) Calculate actual cost per mile based on price of gasoline This option allows you to come up with a pretty accurate assessment of the gasoline cost on a trip. You will be asked for the price of a gallon of gasoline. Enter it like so: 1.089 would indicate a price of one dollar, eight point 9 cents per 9 gallon. You will also be asked for the gas mileage of your vehicle. This should be entered in miles per gallon. For example, if gasoline was a dollar eight point 9 and your car got 30 miles per gallon, you would enter the following to the first question: 1.089 <enter> and the following to the second question: 30 <enter>. Roadways PC is accurate to 2 decimal places on cost per mile to operate your vehicle. For the above example, you would find that the cost to operate your vehicle for one mile would be 3.63 cents. This takes into account only the cost of the gasoline and not wear and tear on you car. 2) Calculate cost per mile on a cents per mile rate Use this option if you want to calculate a cost per mile based on a set per mile rate. For example, if you get reimbursed by your company at the rate of .24 cents per mile, you would select this option. You will be asked what rate per mile you want to use. You must enter this amount as a decimal number. For example, if you get 24 cents per mile, you would enter .24 and press <enter> . If you forget the decimal, Roadways PC will remind you and give you some instructions. 3) Don't do a mileage calculation This will turn off the mileage rate calculations. If you select this option, you will not have the mileage rates displayed on the route screen or on your printout or disk save. If you selected one of the first 3 options, you are asked if you want to save this rate to disk for permanent use in Roadways PC. If you do, press 'Y', if not, press 'N'. If you pressed 'N', you will be asked if the amount calculated is correct. If it is, press 'Y' and you will be returned to Roadways PC and that rate will be used until you exit Roadways PC, or change it. If the rate calculated is not the one you want used for routes, press 'N' and you will then be asked if you want a mileage rate calculation done. If you answer 'N' to this question, there will be no mileage rate calculations on your routes, until the end of the current Roadways PC session or until you change it again by pressing 'M' at the City Selection screen. 4) Return to Roadways with no changes This option does just what it says. If you select this option, you will be returned to the main city selection screen, with the last selected mileage rate in use. As with most of the other screens in Roadways PC, this screen also supports a mouse. The mouse cursor will appear when it can be used. 10 Default Settings Next on the Utilities menu is the option to change the default settings of Roadways PC. Once you select this item, you can change any of the following items: 1 - Printer type - You can choose any of 5 options for the type of printer you have. 2 - Display type - Choose color, monochrome or Hercules displays. 3 - City datafile name - Choose the datafile Roadways will use. This is of special importance to folks that want to use datafiles for other countries or specific files for a particular state or region. These datafiles must be created by users and some have already been made, and are available on the Roadways PC support bulletin board. See the beginning of this document for more information on the support BBS. 4 - Change default speed used to figure driving times - This option lets you change the speeds used to figure the estimated driving times on the final route. If you change anything here, please note that upon exiting back to Roadways PC (by menu option 5) the driving time file will be re-created to reflect your changes. However, in order for these changes to take effect, you must re-start Roadways. For this reason, I recommend using option 6 after changing things here. 5 - Go back to Roadways PC - Lets you return to Roadways PC without using the changes you have selected. The changes will be saved to the ROADWAYS.CFG file, but until Roadways is re-started, they will not take effect. 6 - Re-start Roadways PC - This will reload and run Roadways PC to enact any changes you have made to the defaults. 7 - Get help - This option will bring up a screen of helpful information about each of the options. The Set Defaults options work just like their counterparts in the INSTALL program, so if you have questions or problems, take a look back at the section of this manual called 'Installing Roadways PC on your Computer'. The Mouse is fully functional on these screens as in most of Roadways PC. When you select the option to return to Roadways, the options you have changed will be saved to the ROADWAYS.CFG file, providing you made changes. Set Home (Starting) City If you are going to run several routes all from the same starting point, you can save quite a bit of time by setting that city as the default starting city. 11 When this option is selected, you will be taken to the main city selection screen. You will notice that just below the menu bar, will be a prompt telling you to select the default starting city, or press zero to for no default starting city. You can use the cursor keys or mouse to select the city you wish to be the default starting city. Once you choose it, a block will appear showing the starting city and you will only need to choose the ending city. All routes run after selecting this will ask for only the ending city. This option will only be active until you leave Roadways PC or go back into the 'Set Home (starting) City' selection and press '0'. This will turn off the default selection and you will be able to choose both the starting and ending cities as usual. Re-run Last Route This is a very handy feature if you are wanting to make several comparisons using different re-imbursement figures for mileage or want to see if there is a difference in fastest time versus shortest distance. Selecting this option will re-use the last selected starting and ending cities. Toggle Shortest Time/Dist This option allows you to decide whether you want the fastest route or the shortest. In most cases, the two are the same, but if there are a lot of county roads, state roads or passage through a state with a 55 mile per hour speed limit, the times could vary quite a bit. You may find that a route is quicker when you take a slightly longer (mileage wise) drive because of the speed limits. Selecting this option will toggle the calculation to either the shortest (quickest) time or the shortest distance (the default). You can tell which is currently selected by looking at the upper right hand corner of the screen, in the menu bar. Due to routes being slightly different based on whether you start in a 65 mph zone or 55 mph zone, when you select this option, the route is actually run from both directions. The one problem with this is that you could wind up with the route being opposite from the one you want in direction. For example, run a route from Washington, D.C. to St. Louis, Mo. with the shortest time option activated. You'll find that the route displayed shows from St. Louis to Washington. This can be somewhat confusing and I hope to be able to fix this soon. ROUTE SCREEN Once the route is complete, the screen will clear and the route will be displayed. At this point, you have five more options: 1. Press 'P' to print the route out to your printer. 2. Press 'O' to save the route to disk. 12 3. Press 'M' to see Mileage information if it is enabled. 4. Press 'Q' to Quit Roadways PC completely. 5. Press the Spacebar to do another route. Print You may print the route out as many times as you wish. Simply press 'P' for each copy you want. When you are done printing, you may either quit or run another route. A help menu is available on this screen as well. To activate it, press any key not highlighted on the screen in a command box. I recommend either 'H' or 'F1' since these are the normal help commands in other programs, but any unassigned key will do. The right mouse button will also turn this screen on. Once the help window is open, you can close it by pressing either ESC, <enter> or the space bar, or by clicking in the upper left hand corner or on the <CLOSE> spot with the mouse. If you calculate a route that is longer than will fit on a single screen, you will see two little boxes at the bottom of the screen that say Scroll Up and Scroll Down. By using the arrow keys or the U and D keys, you can scroll through the list of cities at your leisure. Disk Output Saving routes to disk is very simple. From the Route sceen, press 'O'. Roadways PC will ask you for a path and filename. If you want to save the route in the same directory as Roadways, all you need to do is enter the filename you want your route saved under. Do not enter an extender, only a valid MS-DOS filename of eight characters or less. PLEASE NOTE: You cannot save any routes under the filename ROADWAYS. Roadways PC will not allow this, since it could be possible to overwrite one of the program files by accident. Also, if you at any time change the extender from .RDW to another, Roadways PC will not be able to find the file if you wish to retrieve the route in Roadways PC. All Roadways files are saved with the extender .RDW and are simply text files. There are no special characters or funny formatting. This was done to make it easy for you to read into your favorite word processor for inclusion in a letter or document you are preparing. Mileage Calc. Selecting this option will open a small window in the middle of the screen that displays the mileage calculations if they have been enabled. If you chose not to do mileage calculations, a message will be displayed in the box informing you of this. If you chose to do mileage calculations, the following information will be displayed: The mileage rate in cents per mile 13 The total mileage cost one way The round trip mileage cost As with other windows in Roadways PC, this one can be closed by pressing the ESC, <enter> or spacebar keys or by clicking on the <CLOSE> spot or upper left corner of the box. Quit This option will end your Roadways PC session. Space Bar to Continue Pressing this will take you back to the main city selection screen. If you haven't printed out your route or saved it to disk, it will be lost. However, if you suddenly realize this has happened, before doing anything else, you can select 'Re-run Last Route' from the Utilities menu. CONTROLLING ROADWAYS PC WITH A MOUSE Roadways PC is a program that lends itself well to a mouse or pointing device. Use of the mouse is almost intuitive, since it makes sense to point at what you want. This is the philosophy around which the mouse interface was designed. When you first boot up, after the copyright screen, you are presented with a choice of sorting the cities by either city or state. Simply move the mouse cursor to the one you want, and click with the left button. You can click on any part of the word, not just the first letter. Once at the main menu, the following is the assignment of the mouse buttons: Left Button - Select button Right Button - Activate the Keyboard help window As this implies, to choose a city, select a menu item or do something in a box that is on the screen, just position the mouse cursor over what you want and press the left button. To page through the cities, simply go to the boxes at the bottom of the screen. Here is the function of the boxes: NEXT PAGE - Selects the next page (screen) of cities PREVIOUS PAGE - Selects the previous page (screen) of cities By using the mouse cursor and clicking with the left mouse button on your selection, you can page through the cities effortlessly, and select your starting and ending cities. The same thing goes for the other screens. When you see a box with several selections in it, simply click on the word or box you want. 14 [Yes/No] PROMPTS When using a mouse, you can answer a yes or no prompt by simply putting the mouse cursor over your choice. For example, after selecting the ending city, you are asked: Is this Correct <[Y]es/No>? To answer yes, position the mouse cursor over the response you wish to make and click the left mouse button. This is the way to answer all Y/N prompts if you do not want to use the keyboard. This includes the ones when exiting Roadways. Using the Mouse on the Route Screen The only active mouse areas on the route display screen are in the box at the bottom of the screen. Here you have the options of either Printing, Disk Output, Mileage display, Quitting or Space bar to continue. By clicking with the left mouse button on the word with the highlighted letter, you can select that option. Also, if you have a route longer than the screen will display all at one time, you can click in either the Scroll Up or Scroll Down box to scroll the city route display. Again, you do not have to click on the highlighted letter, just anywhere on the word that contains the highlighted letter. QUITTING ROADWAYS PC To end your Roadways PC session, go to either the main screen (the one that contains the city list) or the route display screen. You may either press 'Q' or click on the appropriate menu selection with the mouse. COMMAND LINE SWITCHES There are several command line switches available to make loading and running Roadways PC easier and more customizable. Here are the command line options: /C - Load Roadways and sort the cities in City order for display /S - Load Roadways and sort the cities in State order for display /I - Run the city sorter program (creates ROADWAYS.CTY ROADWAYS.STA, and ROADWAYS.TIM) /? - Provides help on the Command Line switches If at any time you cannot remember what the different switches are, simply type: ROADWAYS /? This will display all the switches available and return you to the DOS prompt. The /C and /S switches speed entry into Roadways PC, by 15 selecting ahead of time, the way you want the cities displayed; whether by city or by state. You will find out more about using the /I switch in the coming section. ENVIRONMENT USE If there is one particular setup you always want to use, you can install it in an environment statement. You can have up to 3 separate environment switches to activate options in Roadways PC. In reality, if you look at the list of possible command line switches, you will notice that there is really only a need for one switch. The most obvious use for this is to add the capability to have Roadways PC come up with the cities listed either by city or by state. Here are the options available: SET ROADWAYS =/C Makes Roadways PC come up sorted by City SET ROADWAYS =/S Makes Roadways PC come up sorted by State To use one of these, just add the appropriate statement above to your AUTOEXEC.BAT file. Please note that the command line will override whatever environment switches you choose. While you can use some of the other command line switches in the environment, I don't recommend it, since Roadways PC will come up with those options selected every time you run it. ADDING CITIES TO ROADWAYS PC Obviously, this program would be of only limited use if it could not be expanded and customized. Since the initial database is fairly limited, it would be good to be able to add new cities. There are two options for adding cities: First, you can order the City Editor from the author of Roadways PC for only $10.00. This is not a shareware program, but it will greatly speed the entry of cities and reduces the possibility of errors. The second option is fairly easy, but does require some planning. Manually! Here I will detail the manual method. Before adding your first city, make sure you have the following available: A good road atlas A calculator (to help add up the number of miles) A printout of the datafile ROADWAYS.DAT A backup copy of the datafile ROADWAYS.DAT (VERY IMPORTANT!!!) While I can't help you with the first two, I can help you get a good printout of the data file. 1. Set up your printer and make sure it is on-line. 16 2. At the DOS prompt, type COPY ROADWAYS.DAT PRN <enter> The data file should now print out. Be forewarned. This is a fairly long datafile (more than 5 pages) so make sure you have enough paper! Once you have all of the items at hand, sit down at a table and lay the data file printout out in front of you. The first 4 lines should look something like this: 201,8 1,ALBANY,NY,5,156,90,146,151,90,85,105,87,88,23,-7,154,14,88,142 2,ALBERT LEA,MN,4,87,90,262,94,35,93,147,90,168,47,35,148 3,ALBUQUERQUE,NM,4,56,40,323,37,25,365,52,25,257,192,40,114 Let's look at what each piece of this data means: The top line is very important. This line contains two pieces of data indicating the number of cities in the datafile and the maximum number of connections that any one city can have. In this case, the first number tells us that there are 201 cities in the datafile. Your listing will have a larger number here more than likely, as new cities are being constantly added and the datafile is growing regularly. The second number tells Roadways PC what the maximum number of cities any one city is connected to. This will become more apparent as we move on, so don't worry too much if you don't understand yet. On the second line is the first piece of city data. Please note that the cities are numbered from 1 to 201 (in this example. Yours may be higher), consecutively. YOU MUST NOT MOVE THE CITIES AROUND! You cannot change the order of the existing cities or remove a city without invalidating the entire listing. You can remove the last city or put a new city on the end, but that is the extent of the modification you can make to the city file. The city data is set up like so: CNUM,CITY,STATE,CONN,C1,R1,D1,C2,R2,D2,C3,R3,D3... CNUM is the city number and applies to this line only! In our example, CNUM for Albany is 1. CITY is the city name. STATE is the state name. CONN is how many other cities this city connects to. In the case of Albany, it connects to 5 other cities (in the example). C1 is the city number of the first city that this city connects to. In our example, the first connection from Albany is to city 17 number 156, which should be SYRACUSE,NY. R1 is the number of the route by which this city connects to the city indicated by C1. Albany is connected to city number 156 by interstate 90. D1 is the distance from this city to the city indicated by C1. Albany is connected to city number 156, by interstate 90 at a distance of 146 miles. C2, R2, D2, C3, R3, D3, etc. are the other cities that connect to this city, in exactly the same format as C1, R1, and D1. The data for each connecting city is always entered in this format: City number, route number, distance. Spaces are not allowed anywhere but in the actual city name. To make it easier to understand adding a new city, let's take a look at how city number 201 was added to the data file. If you haven't already, print out the city data file, ROADWAYS.DAT. Take a look at city number 201. We are going to pretend that this city does not yet exist in the datafile. What we want to do is add the city MARION, Illinois. By looking at my atlas, I have decided that I want it to connect to three other cities that are in the datafile already. The cities I want Marion, Illinois to connect to are: Mt. Vernon, Il. (city number 99) Paducah, Ky. (city number 112) Sikeston, Mo. (city number 145) From my atlas, I get the route information about the roads like so: Mt. Vernon, Il. is 53 miles away on interstate 57 Paducah, Ky. is 42 miles away on interstate 24 Sikeston, Mo. is 60 miles away on interstate 57 Now, I just have to build my new line entry. Here are the steps for this example: 1. First is the new city number: 201 2. Next is the city name: MARION (all caps) 3. Next is the state name: IL (two letter abbreviation) 4. The number of cities we want to connect to: 3 5. City number of the first connecting city: 99 (Mt. Vernon) 6. Route number of the first connecting city: 57 18 7. Number of miles to the first connecting city: 53 8. City number of the second connecting city: 112 (Paducah) 9. Route number of the second connecting city: 24 10. Number of miles to the second connecting city: 42 11. City number of the third connecting city: 145 (Sikeston) 12. Route number of the third connecting city: 57 13. Number of miles to the third connecting city: 60 Our new line should look like this: 201,MARION,IL,3,99,57,53,112,24,42,145,57,60 The order of the cities in the line is not critical, however the format of the data is. In other words, it's ok to put Sikeston, Mo. as the first city in the line of connecting cities, however it is not ok to put the number of miles before the route number, since Roadways PC will think the route number is the distance and vice-versa. Once you have developed the new line, you must now go and make the connection at the other end. For instance, you have added a connection to city number 99 (Mt. Vernon, Il), but Mt. Vernon still does not have anything showing it's connection to city number 201. To complete the connection, go up to city number 99 and increase the number of cities it connects to. Next add the connecting city information. In this case you would add the following to the end of the line: 201,57,53 This should look familiar. 201 is the number of the city that was added at the end of the datafile. 57 is the route number from Marion, Il. to Mt. Vernon, Il., and 53 is the number of miles between the two cities. Repeat this for each of the connections made to the new city. To simplify matters, I usually just use a pencil to write the new information on the datafile printout. This way, I can verify that I haven't left anything out. Once you have finished adding cities and making the changes to the printout, load up your favorite text editor. Please be aware that you should avoid using a word processor if possible, unless you are very familiar with using it to make a true ASCII file. You MUST save the datafile as an ASCII file with hard carriage returns ONLY at the end of each line of data. If you 19 break any of the data lines anywhere other than at the end of the last piece of data for that line, Roadways PC will not work. I recommend using an editor such as MEDIT or even EDLIN, if you are familiar with it's use. Different Kinds of Roads Roadways PC allows three kinds of roads to be used. They are 1) Interstates, 2) State Highways, and 3) Turnpikes. To differentiate between them, you use the following rules: 1) To specify an Interstate, Simply type the number of the interstate (i.e. 64 would indicate interstate 64 or I-64). 2) To specify a State Road, simply type the number of the road as a negative (i.e. -64 would indicate US-64). 3) To specify a turnpike, simply type the number 0 (zero). This will cause Roadways PC to print the word Turnpike, instead of the highway number. Things to Keep in Mind Here are some important things to keep in mind when adding cities: 1. NEVER insert a city into the datafile anywhere but at the end! 2. NEVER delete a city from the datafile, unless you are prepared to either delete all of the cities after the city you want to delete or completely rebuild the file to renumber all the cities after the deletion and change all references to the cities to the new numbers. 3. After adding a new city or connection, make sure you go to the cities connected to and make the connection back to the new city or connection. 4. If you add a city to the listing that is on the path between two cities that are already connected, it's best to remove the connection between the two farthest cities and connect them through the in-between city. Once you have made all the changes to the datafile, go to the top of the file to the very first two pieces of data. If you remember, in our example these were the numbers 201 and 8 separated by a comma. You will need to change the first number to reflect the total number of cities now in the data file. For instance, if the last city is city number 205, you should change the 201 to 205. Also, if any of the cities connects to more than 8 other cities, you will need to change the second number to the maximum number of connections. For example, if the city with the largest 20 number of connections has 10 total connections, you will need to change the number 8 to a 10. The City Sorter Now that all of your changes have been made, save the datafile and exit your editor. If all has been done correctly, you should now be ready to run Roadways PC with the city sorter activated. To do this, type: ROADWAYS /I <enter> This will run the city sorter, recreating the sorted city files with your changes included. It will also create the time datafile used to figure the fastest route. This file will be created using the speeds that were saved in the configuration file, either from running the INSTALL program or from changing the default speeds in the Utilities menu from within Roadways PC. After the new datafiles have been created, Roadways will run, and you should see your added cities in the list. I recommend you try some routes, in both directions, on your cities to make sure that the information you put in is correct and that you didn't make any errors. Common Pitfalls When Adding cities Probably the single biggest pitfall when adding cities is the temptation to try to add new cities without a printout of the data file. This is NOT a good idea, and can result in errors or omissions. A recommendation from one of Roadways PC's registered users was, "don't try to add more than 3 cities at a time" (thanks for the hint, George!). This will greatly reduce the probability for error. Another big problem area can crop up if you use a word processor or editor that splits the data lines. When doing an ASCII save, these programs will frequently put a hard carriage return at the end of each screen line instead of at the end of the physical line. This is why it is very important to keep a backup of the datafile on hand, in the event the one you are working with gets messed up. If something goes wrong with your datafile, it will be obvious, as the program will either not run at all or it will give you an error and terminate operation. If this happens, you know something is wrong with your datafile, and you will either have to correct the problem with a word processor or re-copy your original datafile back to the directory or disk you are running Roadways PC from. It really isn't hard to add cities. Just copy your datafile to some other place and play with it. Just remember to run Roadways PC with the /I switch to allow the city sorter to update the lists of cities. TROUBLESHOOTING PROBLEMS WITH ROADWAYS PC 21 1. You get an error message that the ROADWAYS.DAT file is missing - This error indicates that for whatever reason, the file ROADWAYS.DAT is not in the same place as the ROADWAYS.EXE file. There are two ways to fix this: You can re-install Roadways PC from your original disk, or you can just re-copy the file ROADWAYS.DAT to your working disk or subdirectory. 2. You get an error message that there is an error in the ROADWAYS.DAT file at a particular city number - This error usually occurs when you've added a city to Roadways and made an entry incorrectly. I suggest that you print out the datafile and look especially close at the area around the city number where the error occurred, since this is where Roadways found the problem. Usually, the problem is just that either a piece of data was left out or a period was put in where a comma should have been. If you just can't find the problem, drop your printout in the mail to me along with a copy of your ROADWAYS PC disk and I'll see if I can find the problem. 3. Roadways PC says that the sorted datafiles are corrupt - This usually will occur either during or just after these files are created using the /I command line parameter. Usually, this means that something is ultimately wrong with your main ROADWAYS.DAT file. Here is the best way to test this: Try running Roadways PC without any command line switches (i.e. - just type ROADWAYS and press <enter>). If the problem is ultimately in your main datafile, the error listed in #2 above will be displayed. If, however, you still get a message saying the problem is in one of your sorted datafiles, try re-running Roadways with the /I switch and see if it fixes the problem. 4. When I try to run ROADWAYS PC, after the copyright screen, I get an error right away that says I have Roadways PC configured for the wrong display and to select Hercules in the setup program - This error is due to the inability of the Hercules display to work in anything but 80 column text mode. Just re-run the INSTALL program and answer N to whether you have a color monitor and Y to whether you have a Hercules card and monitor, and re-run Roadways PC. This should fix the problem. 22 A NOTE ABOUT THE WINDOWS IN ROADWAYS PC You will notice that the help windows and the mileage calculation window are very similar. For the mouse user, these windows can be either closed or moved at will. To move a window, just click and hold the left mouse button down on the top bar of the window, and draw it where you want it. After the window is closed, it will revert to it's original location if re-opened. You can close the windows by either clicking in the top left corner, clicking on 'OK', hitting <enter>, pressing the space bar or hitting ESC. UPGRADING ROADWAYS PC If you are upgrading from a previous release of Roadways PC, here are the steps you need to take to avoid losing any changes you have made to the city datafiles: 1. MAKE SURE YOU HAVE A BACKUP OF YOUR ORIGINAL ROADWAYS PC DISK AS WELL AS THE NEW ONE!!!!!!!!!!! 2. If you have added or modified your city datafiles, make a backup copy of YOUR city datafiles that contain the changes (ROADWAYS.DAT, ROADWAYS.CTY and ROADWAYS.STA). Put the backup away so you don't accidentally erase or over-write it. If you haven't changed the datafile, you may want to use the newer datafile as it may contain new city data you don't currently have. If this is so, copy everything from the new disk to your ROADWAYS subdirectory, go to step 3 and skip step 6. 3. Copy all the files EXCEPT ROADWAYS.DAT, ROADWAYS.CTY and ROADWAYS.STA from the newer version to your Roadways directory or disk. 4. Delete the file ROADWAYS.CFG from your Roadways directory or disk. 5. Type INSTALL at the MS-DOS prompt. INSTALL should load and run. Follow the steps listed in the section INSTALLING ROADWAYS PC to make the new ROADWAYS.CFG file. 6. Go through the configuration process. When it is done, you should now have a completely upgraded Roadways PC! A key thing to remember is that the new configuration file (ROADWAYS.CFG) is incompatible with earlier releases. BACKGROUND ON ROADWAYS PC The idea for Roadways PC came from a similar program done on the Apple many years ago. This program worked but was very slow and not at all flexible. It seemed to me that a much better 23 implementation of the idea could be had by using the IBM PC with it's far superior processing speed, memory capabilities and the availability of better languages to work from. Initially, Roadways PC was done in GW-BASIC, however it became apparent very rapidly that this was unsuitable. Besides being horrendously slow, it was also bulky, requiring the use of the BASIC interpreter. After discovering Microsoft QuickBASIC 4.0, the entire program was re-written in modular form without line numbers. Several bugs manifested themselves, some of which were in Roadways PC and some which were part of QuickBASIC. At this point, I discovered the Microsoft BASIC Compiler, version 7.1. This is what this version of the program is written in. Here, finally, was the support I needed without the limitations and bugs in QuickBASIC.

Also added Disk Output to the display screen. Added a mouse box with Print, More and Return to Roadways PC Main to the Retrieval screen. 6. Added the mileage rate input to the config screen. 7. Added mileage output to all output screens. 8. Added the option to change the mileage rate from within Roadways with the 'M' key. 9. Updated the documentation to include all of the above features. 10. Changed the Help box to a true window that is closeable and moveable. 11. Put the mileage information on the route screen into a moveable, closeable window. Changes to version 2.5: 1. Pull down menus have been added to the main city selection screen. 2. The route display is scrollable if it exceeds the room on the screen. 3. Starting and ending cities in the route display have been highlighted to make them more visible. 4. A help menu has been added to the route screen. 5. The configuration program has been removed from the main program and revised to include installation to a hard drive. 28 29 Changes to versions 2.51, 2.52 and 2.53: 1. Several minor bugs were fixed that caused problems with calculated dollar amounts in the mileage calculation routines. 2. The Up and Down keys were switched to make the Up Arrow key scroll the list up and the Down Arrow key scroll down. (oops!) 3.
