WORLD29 Version 2.9H Purpose: WORLD29 version 2.9H is designed to provide rapid, graphic representation of the area surrounding any location on Earth. Rapid graphic location determination by several methods is provided. Tables are provided for U.S. State capitals, National capitals, and locations provided by the user. The location can be entered as a latitude and longitude. The user may select a location by typing the name, or a portion of the name, and selecting from the possibilities presented.New locations can be added to the database. The Continents of the world may be displayed. A pointer can be moved to a location on a projection of the world and a new projection centered on that location is created. Distances between selected points can be determined. Storm or other element tracking throughout the world is provided. Data can be entered within the program for future viewing. Single storm or other track plotting is provided. 1 Table of Contents Purpose. . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 Starting the Program . . . . . . . . . . . . . . . . . . . . . 4 The Opening Screen . . . . . . . . . . . . . . . . . . . 4 The Main Menu. . . . . . . . . . . . . . . . . . . . . . 4 The Details. . . . . . . . . . . . . . . . . . . . . . . . . . 6 Option 1 . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 Entry by Latitude and Longitude. . . . . . . . . . . . . 6 CITY VIEW OPTION . . . . . . . . . . . . . . . . . . . . 8 WORLD VIEW OPTION. . . . . . . . . . . . . . . . . . . . 12 OPTION 2 . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 The Continents . . . . . . . . . . . . . . . . . . . . . 15 OPTION 3 . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 Hemispheric views. . . . . . . . . . . . . . . . . . . . 16 Option 4 . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 Find using CITY or COUNTRY name. . . . . . . . . . . . . 17 Option 5 . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 Capitals of the USA. . . . . . . . . . . . . . . . . . . 20 Option 6 . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 National Capitals. . . . . . . . . . . . . . . . . . . . 21 OPTION 7 . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 Other CITIES of note . . . . . . . . . . . . . . . . . . 22 OPTION 8 . . . . . . . . . . . . . . . . . . . . . . . . . . . 24 Enter new info on Tracks . . . . . . . . . . . . . . . . 24 OPTION 9 . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 The Global view. . . . . . . . . . . . . . . . . . . . . 26 OPTION 10. . . . . . . . . . . . . . . . . . . . . . . . . . . 27 Point at a location. . . . . . . . . . . . . . . . . . . 27 OPTION 11. . . . . . . . . . . . . . . . . . . . . . . . . . . 29 Approximate distance between Cities. . . . . . . . . . . 29 OPTION 12. . . . . . . . . . . . . . . . . . . . . . . . . . . 31 Plot any one Track . . . . . . . . . . . . . . . . . . . 31 OPTION 13. . . . . . . . . . . . . . . . . . . . . . . . . . . 33 Name the City. . . . . . . . . . . . . . . . . . . . . . 33 2 PREPARING A WORKING DISK. . . . . . . . . . . . . . . . . . . 34 HARD DISK. . . . . . . . . . . . . . . . . . . . . . . . 34 FLOPPY DISKS . . . . . . . . . . . . . . . . . . . . . . 36 CUSTOM CONFIGURATION . . . . . . . . . . . . . . . . . . . . . 37 MONITOR SELECTION. . . . . . . . . . . . . . . . . . . . 37 CHECK FOR FILES. . . . . . . . . . . . . . . . . . . . . 37 SPECIAL SUBDIRECTORY . . . . . . . . . . . . . . . . . . 38 SUPPLEMENTAL FILE NAME . . . . . . . . . . . . . . . . . 38 COLOR SELECTION. . . . . . . . . . . . . . . . . . . . . 38 FILE FORMATS . . . . . . . . . . . . . . . . . . . . . . . . . 40 CUSTOM.LOC files . . . . . . . . . . . . . . . . . . . . 40 TRAKxxxx. files. . . . . . . . . . . . . . . . . . . . . 41 SUP.DAT files. . . . . . . . . . . . . . . . . . . . . . 41 REGISTRATION . . . . . . . . . . . . . . . . . . . . . . . . . 43 3 Starting the Program The Program is designed to run on any graphics PC compatible system with more than 256kb of memory without modification. The single exception is the case of a HERCULES or Hercules Compatible system. For these systems a CGA SIMULATOR must be run before running WORLD29. The program is started by typing WORLD29 and hitting ENTER. The Opening Screen You are presented with a stylized depiction of the world. This screen is on a timer. If you do nothing the main menu will appear. If you are in a hurry just hit ENTER to go directly to the main screen. The Main Menu Once an overlay and location file have been selected, the screen will clear and you will be presented with a Menu of 14 options. You will also see a report of the CURRENT .DAT and .LOC files and a way to end the program. To end an Option early type END or QUIT at a text prompt. The top of the screen lists the program name and version number. Option 1 - 1 - Select by LAT and LONG Permits entry by latitude and longitude. Once entered you will be presented with further options to enable the creation of a map centered on the latitude and longitude you have entered. Option 2 - 2 - Select by large area name Permits entry by Name. If you want a map of South America you type S. AM and hit ENTER. A map will be created based on the name you select from a list. Option 3 - 3 - Select by Hemisphere Permits entry by Hemisphere. A map will be created of the selected hemisphere. 4 Option 4 - 4 - Find using CITY or COUNTRY name Permits the user to create a map centered about a location identified in the data base. Searches may be made based on partial names. Search includes the LOCation file selected. Option 5 - 5 - Capitals of the USA Selection of a state capital is made by number from a list of the capitals. A map is created centered on that capital. Option 6 - 6 - National Capitals Selection of a national capital is made by number from a list of over 200 national capitals. A map is created centered on that capital. Option 7 - 7 - Other CITIES of note Selection of a location from the data base maintained by the user is made by number. A map is created centered on that location. This data base is the Location file selected. Option 8 - 8 - Enter new info on Tracks Allows the addition of information to tracking data Option 9 - 9 - The Global view Permits entry by latitude and longitude. Once entered you will be presented with further options to enable the creation of a global depiction centered on the latitude and longitude the user has entered. Option 10 - 10 - Point at a location A depiction of the world allows you to move a pointer and create a map centered on the location of the pointer. Option 11 - 11 - Approximate distance between Cities Calculates Great Circle distance between any two locations in the data base, including the LOCation file. Option 12 - 12 - Plot any one Track Permits the isolation of any single track. Option 13 - 13 - Name the City A simple game randomly creates a map and challenges the user to name the central location. Option 14 - 14 - Select new DAT or LOC file. Allows you to change OVERLAY and or LOCATION files. To end the program type 99 or END and hit the ENTER key. 5 The Details Option 1 Entry by Latitude and Longitude On the Main menu type 1 and hit ENTER. Purpose: This option provides a variety of maps centered on user entered latitude and longitude. It permits the rapid display of locations in proximity to a given latitude and longitude. This selection presents the user with an input module. The user is reminded that "Just ENTER will re-enter the last position". This means that, in general, if you want the same latitude (or longitude) as the last time, when asked for a lat, you can just hit ENTER. The first question LAT (-for SOUTH) ? is what latitude is the user interested in. (He is also reminded that a southern latitude may be entered as a negative number). The user can respond to the question in the form DD MM H or DD.FF. DD stands for whole degrees MM for minutes H for Hemisphere (N or S) FF for fractional degrees (1 minute =.0167 degrees) DD can be from -90 to 90 (if less than 10 degrees a 0 must precede the degrees) MM from 0 to 59 H can be any of s, S, n, or N. Entries over 90 will be changed to 90 degrees. A SPACE MUST separate degrees from minutes. For the Northern hemisphere the N may be left off, if present, it MUST be separated from the minutes by a SPACE. The minutes may be eliminated if whole degree entry is desired. 6 Alternatively, the user may enter the latitude as a decimal number of degrees (I.E., 45 30 S could be entered as -45.5) Acceptable entries are: 34 15 N 34 15 (Northern hemisphere assumed) 34 N 03 02 n (3 degrees 2 minutes North) 34 (34 deg. Northern assumed) 34.25 ( 34 15 N) 34 15 S 34 s -3.5 (3 deg 30 min. South) The user is then asked to enter a longitude. LONG (-for EAST) ? The response should be in the form DDD MM H or DDD.FF. DDD may be from -179 to 179 degrees MM from 0 to 59 minutes H can be e, E, w or W. FF is fractional degrees A negative number will be assumed to be Eastern hemisphere. Formats are the same as for latitude with the exception that there are 3 digits in the degree field. DEFAULTS The following questions all have DEFAULT answers represented by what is enclosed in the [] symbols. If the default choice is made (hitting ENTER in response to each question) for all the questions in this segment the resulting map will: Be a Mercator type projection in which the selected latitude and longitude is at the center of the screen. It will use a scale of 3 (the medium size area). The names of all appropriate locations in the internal and external data base will be printed on the map. These defaults were chosen to provide the most rapid display of the most likely desirable information. The alternatives are presented to cover those cases where other information is desired. 7 WORLD or CITY VIEW You are to choose "World view or nearby [C]ities" You type the letter W or C followed by ENTER or just hit ENTER. This prompt is to remind you that there are two types of maps available. The World view is a spherical map (as if on a globe) and the City view is more appropriate for viewing smaller areas (Mercator type projections). As noted by the [] surrounding the C in Cities, Cities (or Mercator) view is the default and will be selected if you just hit the ENTER. We will examine this choice first. CITY VIEW OPTION Purpose: To provide the quickest display of a relatively small section of the earth for rapid identification of locations in close proximity. SCALING The next question Scaling Factor 1,2,[3],4,5 ? has to do with scale of the map to be presented. A response of 1 provides approximately 60 degrees of longitude (about the size of the U.S.A). A response of 5 shows about 5 degrees (a little bigger than Massachusetts.) The range is as follows: 1 - 60 degrees of longitude 2 - 30 3 - 15 4 - 8 5 - 5+ degrees of longitude Display level selection allows you to control the amount of information (words) printed on the screen. The following display is intended as a reminder to the user of the variations permitted. 1=level 1 only 5=level 5 only A= accumulate level + lower levels eg. A5 NAMES= only locations with xxxxx in them Y or ENTER= only Capital cities N= no locations Do you want City names [Y]NA(1-5)? The first 6 lines are to remind you of the options you have available. 1=level 1 only - is to remind you that if you answer the question with a 1 you will see only the capital cities and the locations from the location file you selected in the opening sequence which are identified with a 1. 8 5=level 5 only - reminds you that only capitals and locations with an identifier of 5 will be displayed. A= accumulate level + lower levels eg. A5 - is to remind you that if you select A5 you will see all capital cities and all locations from the location file selected in the opening sequence that are on the display. eg: A1 displays all capitals and all with the 1 identifier. A2 displays all capitals and all with the 1 or 2 id. A2 displays all capitals and all with the 1 or 2 id. A3 displays all capitals and all with 1, 2, or 3. A4 displays all capitals and all with 1, 2, 3, or 4. A5 displays all capitals and all locations on the display. ------ ONLY AVAILABLE ON EGA/VGA SYSTEMS ------- NAMES= only locations with xxxx in them - is used only after a search for a city name (OPTION 4 on the main menu). The xxxxx will be replaced by what you searched for. ONLY AVAILABLE ON EGA/VGA SYSTEMS eg. You used option 4 to search for SAN. The program answers with SANTA FE, NM. When asked if you want City names you answer with NAMES. Select a scale of 1, 2, or 3. You will see the mark for SANTA FE and you will see some other marks in TEXAS. THESE are the locations from your location file which have the letter SAN in their name. (using scale one you will also see marks at SAN FRANCISCO, SAN DIEGO, and CABO SAN LUCAS if using the CUSTOM.LOC file that comes with WORLD29). ------ ONLY AVAILABLE ON EGA/VGA SYSTEMS ------- SHOW TRACKS You will be asked: "Show Tracks y[n]" The default response, NO, is designated by []. If chosen no tracking data will be displayed. If response of Y, y, Yes, or yes is received a menu will appear. It will consist of all files that begin with the letters TRAK that exist in the specified subdirectory (see CUSTOM CONFIGURATION) will appear. The first name will be highlighted. If you wish to plot the tracks stored in this collection hit ENTER. If you want to plot tracks stored in another collection of tracks use the up or down arrows to highlight the appropriate collection name. NOTE: Only 5 collection names are displayed at one time. If more exist a down arrow will appear at the bottom of the box. The down arrow will scroll the display until all have been seen. You can scroll back through the list with an up arrow until you select a collection by highlighting it and hitting the ENTER key. Once you have selected a collection of tracks the map will be created with the appropriate tracks. 9 MAPPING The program will create a map centered on the latitude and longitude chosen. Colors will be determined based upon the capabilities of the system and the mode selected in the configuration process. (Configuration should only be changed by knowledgeable personnel) A circle in the center of the screen represents the entered latitude and longitude. The latitude will be printed at the center right of the screen and the longitude at the center bottom. IF YOU ANSWERED AFFIRMATIVELY the question "Do you want City names [Y]NC(1-5)?" the appropriate data bases will be searched. At any time the ENTER key can be depressed to end the search. SEE PAGES 8 & 9. National and State capitals will be identified by a small circle. The name of the city and the state name or nations name will be displayed to the right of the circle. All locations identified by a display level of 1 will be identified by a small box with the name to the right. All locations identified by a display level of 2 will be identified by a chevron with the point up. All locations identified by a display level of 3 will be identified by a chevron with the point left. All locations identified by a display level of 4 will be identified by a chevron with the point right. All locations identified by a display level of 5 will be identified by a chevron with the point down. Selecting 1 will display capitals and all locations at display level 1. Selecting 2 will display capitals and all locations at display level 2. Selecting 3 will display capitals and all locations at display level 3. Selecting 4 will display capitals and all locations at display level 4. Selecting 5 will display capitals and all locations at display level 5. 10 To display a map with no locations identified select N in response to the prompt: "Do you want City names [Y]NC(1-5)?" To display only the capital cities enter a 0. There is no way to display any given display level without displaying the capitals. Note: Eliminating a capital If there is an error or change in the name or location of a capital (Berlin or Bonn???) please notify the author. As an interim fix you can add a location to the CUSTOM.LOC file which will overwrite the erroneous entry. Find the location of the capital you wish to eliminate (using WORLD29, of course). Convert the minutes to decimals (1 minute =.0167 degrees). Using your editor or word processor (in ASCII mode - see CUSTOM below) add an entry consisting of: "------,-----" (The number of - before the , equals the number of letters in the city name. Those after the , equals the number of letters in the country name) a comma The latitude of the city (in decimal degrees. Negative numbers represent the southern hemisphere) a comma The longitude of the city ( in decimal degrees. Negative numbers represent the eastern hemisphere) a comma 0 ( the number zero) This should look like: "-------,------",23.6,-120,0 If you use spaces the capital name will be overwritten by some other name. 11 WORLD VIEW OPTION Purpose: To provide the user with a spherical (or global) view of the data. This representation, although slower than others, displays shapes and areas as they are on the earth. It is the best choice when a very large area is required. If you chose W, w, or World and hit ENTER you will be asked for specifics about the global projection you want. DEFAULTS The following questions all have DEFAULT answers represented by what is enclosed in the [] symbols. If the default choice is made (hitting ENTER in response to each question) for all the questions in this segment the resulting map will: Be a global (spherical) type projection in which the selected latitude and longitude is in the center of the screen. It will use a scale of 1 (the entire hemisphere). No tracks will be plotted. No state borders will be plotted. No political borders will be plotted. Latitude and longitude lines will be plotted at 10 degree increments. These defaults were chosen to provide the most rapid display of the most likely desirable information. The alternatives are presented to cover those cases where other information is desired. GLOBAL SCALING You will be asked a scaling question. Scaling Factor [1],2,3,4,5? The default [1] is a scale of 1. This scale will show an entire hemisphere. Scale 1 = hemisphere Scale 2 = area equal to North America Scale 3 = area slightly smaller than USA Scale 4 = area about the size of the mid west Scale 5 = area about the size of Iowa, Illinois, and Indiana 12 The screen will clear and you will be asked a series of questions to determine which of the available information you wish displayed. Your selection will determine the absolute time necessary to create the final display. The less data you require the faster the process. TRACKING You will be asked. Do you want tracks Y[N]? The default is N for No, do NOT plot any tracks. A response of Y, y, or Yes will cause a selection menu to print to the screen. It will have a heading consisting of the preselected subdirectory for TRAKS files (selected in the WORLD.CNF file) and the word TRAK*. Below will be listed up to 5 TRAKxxxx files (xxxx can be any valid character), which have been previously created. If there are more than 5 TRAKxxxx files the list can be scrolled until all have been displayed. To select one of the files to be displayed, press the down arrow until the desired filename is highlighted. If you go too far, you can use the up arrow to retrace your steps. When the desired TRAKxxxx file is highlighted, press the ENTER key. After the selected section of the globe is displayed, the tracks stored in the chosen TRAKxxxx file will be displayed. STATE BOUNDARIES Do you want state boundaries Y[N]? The default is N for No, do not plot state boundaries. A response of Y, y, or Yes will result in the final display including the appropriate state borders. POLITICAL BOUNDARIES Do you want political boundaries Y[N]? The default is N for No, do not plot political boundaries. A response of Y, y, or Yes will result in the final display including the appropriate political borders. Political boundaries are the generally agreed to borders of the nations of the world as opposed to the physical edge of the continents. These borders change from time to time and will be reflected in updates when the new borders become generally accepted by the majority of countries of the world. 13 GRID LINES Do you want grid lines [Y]N? The default is Y for Yes, plot latitude and longitude lines at 10 degree intervals. A response of N, n, or No will omit the latitude and longitude lines from the final display. The screen will clear and a spherical plot of the selected area will be created with the selected latitude and longitude in the center of the screen. When the display is completed, the program will go into pause mode and display a "?" in the upper left corner of the screen. When you are ready to return to the main menu, hit the ENTER key. 14 OPTION 2 Select by large area name On the Main menu type 2 and hit ENTER. Purpose: To provide rapid access to certain preselected large area maps by name of the area. This selection presents the user with an input module. The user is presented with a list of names of preselected views of various areas. The program selects upper case automatically and the response to the question: WHICH AREA ? should be in upper case and should only include the upper case letters used in the listing. If you wish to see a map of South America you would type S. AM and hit the ENTER. When the ENTER key is depressed, the screen will clear and the preselected map will be drawn. If desired, you can add the current TRAKS file to the map by appending the letters TRACKS to your entry. In the above example you would type S. AMTRACKS. 15 OPTION 3 Select by Hemisphere On the Main menu type 3 and hit ENTER. Purpose: To provide rapid access to hemispheric views This selection presents the user with an input module. The user is presented with a list of preselected views. Selection is by number. When the ENTER key is depressed the screen will clear and the preselected map will be drawn. 16 Option 4 Find using CITY or COUNTRY name. On the Main menu type 4 and hit ENTER. Purpose: To provide rapid access to maps of areas surrounding locations when the user knows the name or part of the name. This selection presents the user with an input question: What combination of letters are you looking for? This is designed to be as flexible an entry as possible. Case is ignored. You can type any letter or combination of letters you desire. If you type END you will be returned to the main menu. WORLD29 will search its data base and the current .LOC file for the first occurrence of the letter or letters that were entered. When the program finds the combination of letter in the name of a location in the data bases it will present you with the name it identified and the following choices: [W]orld Area map Select again Look some more? NOTE: The [] denote the default W for World (or global projection). If you hit ENTER at this time a spherical map centered on the location identified will be created based upon further inputs. Magnification .25-10 [1] ? Do you want tracks Y[N]? Do you want State boundaries Y[N]? Do you want Political boundaries Y[N]? Do you want grid lines [Y]N? These questions are the same as described above under OPTION 1, WORLD VIEW OPTION. A for Area map selects a mercator type projection. The follow on questions and reactions will be as described above under OPTION 1, CITY VIEW OPTION. 17 S for Select again will send you back to the "What combination of letters are you looking for?" prompt. L for Look some more continues the search for the next match in the data bases. NOTE: This is a two edged sword! If you enter a single letter there is a high probability that many, many location names in the data bases will include that letter. If you enter a misspelled name of a city or country it is likely that the program will not be able to identify the location. The advantage of this system is that if you are only sure of a part of the name you can enter only that part. You will have a high likelihood that the program will identify the location you are searching for. EXAMPLE of LETTER SEARCH: Suppose we would like to create a mercator type map centered on San Diego, California. From the main menu choose OPTION 4 by typing 4 and hitting ENTER. At the "What combination of letters are you looking for?" prompt we decide that we will only type the letter S. The program will respond with Annapolis, since this is the first entry in the data base with the letter s in it. Since this is not what we want select L for Look some more. The program will respond with Augusta, the next name in the data base with the letter s in it. Obviously, this will take too long, so type S for Select again. This sends you back to the: What combination of letters are you looking for? prompt. This time we decide to really narrow the search and type SAN DIEGO, CALIFORNIA and hit the ENTER key. Unfortunately, this is too much information for the program to find a proper match. The program responds with: I can't identify that!! 18 When you press ENTER you are returned to the main menu. To continue the search you can either type 4 and hit ENTER or just hit ENTER to return to the: What combination of letters are you looking for? prompt. If we now respond with SAN, the program will step you through all locations it can find with the letters SAN in the name. This might be reasonable or we can try DIEGO, which should find the correct location rapidly. ALL the letters you enter must be in the location name stored in the data base in the order you type them including any spaces. This is helpful if you do not know the exact spelling of a location but are sure of at least a few letters. Suppose that you want to find DHAKA,BANGLADESH but don't know how to spell it. It is very likely, from the sound of it, that the letters BANG are in the name. Using OPTION 4 we can type BANG and after 3 or 4 come up with the correct response. If we had entered DAKA, as we might guess, we would not come up with the correct answer. 19 Option 5 Capitals of the USA On the Main menu type 5 and hit ENTER. Purpose: To provide a rapid method for accessing maps of areas surrounding capitals of the U.S.A.. The screen will clear and you will be presented with an alphabetized listing of all 50 states. Each state is identified with a number. You are prompted to: SELECT BY NUMBER? Enter any number from 1 to 50 inclusive. Typing END and hitting enter will return you to the main menu. A number (1-50) will result in the question: World view or nearby Cities W[C]? This question and later questions and will function as described above under OPTION 1 starting at WORLD or CITY VIEW. This option facilitates learning the state capitals in relation to surrounding states and can be used to rapidly find the shortest distance between capitals. 20 Option 6 National Capitals On the Main menu type 6 and hit ENTER. Purpose: To provide rapid access to maps of areas surrounding capitals of the nations of the world. The screen will clear and you will be presented with an alphabetized listing of 60 of the worlds capitals and the prompt: SELECT BY NUMBER (M FOR MORE)? You can select any of the listed names as the center of a map by typing the number associated with the capital and hitting ENTER. If you type END and hit ENTER, you will be returned to the main menu. If you type M and hit ENTER, you will be presented with capitals 61 to 120 and the same prompt. The procedure will be repeated until all capital names have been displayed. If you type M on the last page, you will be returned to the first page. At any prompt you can type any VALID number to create a map. If you type a number greater than the number of the last national capital in the data base, you will be returned to the first page. At any prompt you can type END to return to the main menu. M and ENTER brings up the next page of capitals. Valid numbers will result in the prompt: World view or nearby Cities W[C]? and later questions and responses as above in OPTION 1, WORLD or CITY VIEWS. 21 OPTION 7 Other CITIES of note On the Main menu type 7 and hit ENTER. Purpose: To provide rapid access to maps of areas surrounding locations chosen by the user. This is YOUR section. The files CUSTOM.LOC and USSR.LOC are provided as sample files and are to be maintained by the user. (See CREATOR.EXE and FILE FORMATS below) CUSTOM.LOC is the inclusive list of Names, latitudes, longitudes, and display levels each on its own line and stored as an ASCII file. This file is readable by most word processors such as EDLIN, PC-WRITE, WORD PERFECT (use CTRL-F5, DOS text, to save and load), and WORDSTAR (use N for NON DOCUMENT mode). The file, CREATOR.EXE, provided with WORLD29 can also be used to add locations to CUSTOM.LOC (discussed below). A sample CUSTOM.LOC file is included with the program. Option 7 displays the names of all files in the current .LOC file and associates each one with a number as in option 6. The names are listed with no more than 60 on a display page. The prompt: SELECT BY NUMBER (M FOR MORE)? is used as discussed in option 6. The limits on the number of items a the .LOC file is technically over 30,000 but practically much lower. The program functions properly and option 7 has been tested with over 1500 items in CUSTOM.LOC. A greater limiting factor may be associated with the speed to search the larger .LOC files. This speed will be dependant not only on the length of the file, but also, on the type of media (hard disk is faster than floppy) and the speed of the machine. 22 If you find the time to search the CUSTOM.LOC data base is excessive, you can physically split the file into two or more separate files. WORLD29 now supports LOCation files of over 1000 names. Paging is now handled with the letter M (for More). This provides access to LOCation 999 as well as all others. The display has been adjusted for proper display of up to 9,900 locations. You can page back and forth in the file using the "+" sign before a number. For example if you are on the page displaying LOCation 121 through 180. You know the LOCation you are interested must be a long way from where you are. Instead of repeatedly typing M ENTER, M ENTER, etc. type +1000. If possible WORLD29 will jump to the page containing LOCation number 1000. If you jump too far you can jump back with a +900. You can switch between the + and M as desired. Option 14 now makes it practical to utilize more than one LOCation file in a given session. You may type any filename at the "Location file to use" prompt. The filename may include a drive and a completet path. For simplicity I find keeping all of my LOCation files in the same directory as WORLD29. I also find that having all of my LOCation files retain the .LOC extention helps. WORLD29, however, doesn't care about the name, only the contents. SEE PAGE 40 This flexability also applies to the OVERLAY files. WORLD29 will accept any file that is in the proper format. SEE PAGE 41 Both of the overlay and location questions provide DEFAULT ANSWERS (the answer if you just hit the ENTER key). The DEFAULT ANSWER will be printed above the question inside square brackets []. As in prior version you may answer NONE to the "OVERLAY to use?" question to eliminate all overlays from the program. The "Location file to use?" question, however, will NOT accept NONE - you MUST have a LOCATION file. If you don't have one use the CREATOR program to creat CUSTOM.LOC. Each question will accept a complete filename, including a path to allow you to use files in directories other than the one WORLD29 is in. When you enter a filename WORLD29 will check to be sure it exists and if not give you a chance to re-enter the filename. WORLD29 does NOT, however, check for the proper format at this point. You must insure that the file your tell WORLD29 to run conforms to the standards specified in WORLD.DOC. If the program later finds an incorrect file format the results are unpredictable. NOT DANGEROUS just NOT what you were expecting. All of the features of Option 7 will function in the same manor as in Option 6. 23 OPTION 8 Enter new info on Tracks On the Main menu type 8 and hit ENTER. Purpose: To allow the user to create or make additions to the file TRAKS. The file TRAKS is used as the current or default collection of tracks in option 2 and 3 and must exist before those options are used. The file TRAKS and any files created by the program and renamed to filenames beginning with TRAK are all ASCII files. ASCII can be modified by word processors as discussed in option 7 under the discussion of CUSTOM.LOC. For further information see FILE FORMATS below. The prompt: SHALL I CONTINUE [Y]N? give you the option to return to the main menu without changing or creating the TRAKS file. If you type N, or n, or No you will be returned to the main menu. The DEFAULT response is Y for YES (noted by []) will ask questions to determine what should be added to the TRAKS file. This response will create a file named TRAKS if it doesn't exits. TRACK IDENTIFIER STRING ? This is the request for a name or something to tie sequential entries together. (Originally used for the Name of a hurricane). If later sequential entries have the same IDENTIFIER STRING, they will be linked together as a track. DATE <MMDD> ? The date of the entry. Originally the month and day of the fix in two digit month and two digit day form. This can be any numeric entry. This number is not displayed but can be used for sorting or historical purposes. TRACK STRENGTH OR CONFIDENCE 1-4 1>4 ? A numeric representation of the strength or confidence in the fix. Originally used to represent storm strength as: 1 = Hurricane 2 = Tropical Storm 3 = Tropical Depression 4 = Tropical Wave 24 This number is translated to the size of the circle plotted around the fix with a 1 being represented by the largest circle. LAT? Requests the latitude of the fix. This MUST be in the form of decimal degrees. (44 degrees 30 minutes must be entered as 44.5) Southern latitudes are represented by a negative sign (- 44.25 would represent 44 degrees 15 minutes SOUTH latitude) LONG? Requests the longitude of the fix. This MUST be in the form of decimal degrees. (80 degrees 45 minutes must be entered as 80.75). Eastern longitudes are represented by a negative sign (-123.5 would translate to 123 degrees 30 minutes EAST) DO YOU HAVE MORE DATA Y[N]? The DEFAULT entry is N for No more data. A quick mercator type map will be created centered on the last entered fix. It will show any other tracks in the TRAKS file that occur on the map. A response of Y, y or Yes will take you back to the prompt: SHALL I CONTINUE [Y]N? If you have additional entries you can go on. If you type N, or n, or No you will be returned to the main menu. NOTE: This option can be used to track anything that can be given a latitude and longitude. The key to making continuous track plots is to keep all fixes with the same name in sequence. The TRAKS file is an ASCII file and can be loaded into, manipulated by, and saved from word processors as discussed in option 7. The file can also be sorted with the SORT program from the supplemental programs disk that comes with DOS to keep names together. When some logical collection of tracks is completed, the file named TRAKS should be renamed to something beginning with TRAK. For example each year I rename TRAKS to TRAKSxx where xx is the last two digits of the year. These file (TRAKS89, TRAKS88, etc.) represent collections of hurricane tracks for the appropriate year and can be retrieved and plotted with several options. 25 OPTION 9 The Global view On the Main menu type 9 and hit ENTER. Purpose: This option is provided to permit direct entry into a global or spherical representation. It provides the same features as OPTION 1, WORLD VIEW OPTION but allows the user to select a magnification factor. It is retained only for the convenience of certain customers. Once a global plot has started, it can be interrupted at any point by hitting the ENTER key. This will return you to the pause prompt. ("?" in the upper left of the screen) Hitting the ENTER again returns you to the main menu. 26 OPTION 10 Point at a location On the Main menu type 10 and hit ENTER. Purpose: To provide access to expanded views of areas of the world selected by a pointer. Secondarily, it provides a crude distance calculator. The screen is cleared and a mercator type representation of the world is drawn. A pointer arrow is created in the northern Atlantic Ocean. The pointer can be moved as follows: Up using the UP arrow or the 8 key Down using DOWN arrow or the 2 key Left using the LEFT or the 4 key Right using the RIGHT or 6 key Up and Right using the 9 key Up and Left using the 7 key Dn and Right using the 3 key Dn and Left using the 1 key The program has manipulated the NumLock key to allow this flexibility. It will restore the NumLock key and the CapsLock key to the condition that existed when the program started upon exit by the 99 menu entry. You may move the pointer arrow to any point on the map. Do NOT try to wrap the pointer around one end of the display or the other. As you move the pointer, the latitude of the point will be displayed at the center right of the screen. The longitude will be shown at the bottom center of the screen. The arrow will only move in 1 degree increments. Hitting the E for Escape or End at any point will return you to the main menu. When the arrow is pointing at a place you are interested in, hit the ENTER key. The tip of the arrow will become the center of a new, expanded map. This procedure can be continued through a total of five magnifications. On magnification 5 the CUSTOM.LOC file will be searched and any locations on the map will be plotted. On any EXCEPT magnification 5 you can do some rough (to the nearest whole degree) distance measurement. Move the arrow point to the first location you are interested in and hit the F1 key. At the top of the screen it will print: 27 First fix xx xxx xx will be the latitude of the point of the arrow. xxx will be the longitude of the point of the arrow. You can reposition the arrow and hit F1 again if this was not the point you expected. Remember, the latitude of the pointer is displayed at the right center and the longitude at the bottom center. Now move the arrow until the point is at the second point you are interested in and hit F2. The program will print: Second fix xx xxx xxxx miles just below the First fix. Again the xx will be the latitude of the pointer and xxx the longitude. xxxx will be replaced with the number of statute miles between the first fix and the second fix. You can now move the pointer and hit F2 again for another distance measurement. F1 has remained the same. This can be repeated any number of times. If you want a new first point, place the cursor and hit F1 again. You must select a new second point once you have used F1 or the distance will not be relevant. 28 OPTION 11 Approximate distance between Cities On the Main menu type 11 and hit ENTER. Purpose: To provide rapid calculation of the shortest distance between any two known points on earth. The screen clears and you are asked for a first name. The input is similar to that in option 4. Case is not considered and the entire data base is searched for the letters you enter. The prompt is: Ok or Look more ([O]L,Q)? O for OK is the default. (indicated by []) L for Look more continues the data base search Q for Quit sends you to the pause prompt and then the main menu. Once you have accepted a location you are asked for a second location. The prompts and actions are the same as for the first name. Upon acceptance of a second location the screen clears and a box opens with prompt as below: Approximate distance between FIRST NAME and SECOND NAME is XXXX miles YYY Deg Would you like a map? FIRST NAME is replaced by the name selected above. SECOND NAME is replaced by the name selected above. XXXX is replaced by the approximate number of statute miles between the two locations on a GREAT CIRCLE running through the two. YYY is an approximate bearing on the GREAT CIRCLE route from the first location to the second location. The distance calculator can also be used to calculate the distance between two pair of latitude and longitude coordinates or a named location and a latitude and longitude. When a number is entered instead of a location name it is assumed to be a latitude and you will be prompted for a longitude. Either or both the first and second entry may be either a name or a location. 29 If you respond to the "Would you like a map?" prompt with a N or NO or ENTER you will return to the main menu. If you respond with a Y or y a representative map will be created. NOTE: The map request will provide a rectangular projection displaying both the first point and the second point. The only purpose for this map is to show the relative locations of the two points. The map is often distorted. It is always created from West to East and the line connecting the two points does NOT represent the GREAT CIRCLE route between the points. The connecting line is only to identify the points at each end of the line as the first point and the second point. The first point and the second point can be at either the left or right of the line and no attempt is made to identify which is where. When tracking an item you can rapidly find the distance between any point and the most recent location. Enter the identification of the point in response to the First Name prompt. Enter the word CANE or the word TRACK at the Second Name prompt. You will be presented with the list of track collections. Select the appropriate file. WORLD29 will then tell you the distance from the point to the last entry in the file. 30 OPTION 12 Plot any one Track On the Main menu type 12 and hit ENTER. Purpose: To allow the user to isolate a single track on a map containing the initial position of the track. The screen will clear and a small window will appear listing up to 5 TRAKxxxx files. If more files exist you may scroll through the list using the UP or DOWN arrows. On most systems a highlight will move through the list as you scroll (certain monochrome systems do not show the highlight and will require the user to keep track). When the highlight is on the TRAKxxxx collection name you are interested in, hit the ENTER. The screen will clear and all unique track names in the collection will be displayed. Up to 100 names can be displayed at once. If there are more than 100, they will scroll out of sight. The tracks that scroll are still accessible but breaking the TRAKxxxx file into two separate names is recommended. The prompt: Type the name of the track you want to plot? NOTE: This search, unlike all before, is for an exact match. It is case insensitive, however spelling DOES matter. This is to reduce the chance of plotting the incorrect track. If the program cannot make a match it responds with: I didn't see that one Any response will return you to the main menu where you can start over with the default re-entry into option 12. Once a match has been made you will be prompted: World view or nearby Cities W[C]? Default, questions, and responses are as in option 1 above. Scaling Factor 1,2,[3],4,5? Default, answers and responses are as in option 1 above. 31 Do you want nearest City [Y]N? NOTE: The default is Y for yes. You must type N or n or No to avoid this calculation. NOTE: The Nearest City feature calculates the distance from the initial point of the track to the nearest location. The distance calculation takes place between the plotting of the initial point of the track and the plotting of the second and subsequent points, if any, in the track. In this case the second and subsequent points will not be plotted until you have exited the nearest location routine by responding with an ENTER. 32 OPTION 13 Name the City On the Main menu type 13 and hit ENTER. Purpose: To provide a simple geographic knowledge challenge. Maps are created of the area surrounding randomly chosen world and U.S. capitals. The user is challenged to name the city and country or state. The map is always scale 3, includes the latitude and longitude of the capital, and any other capitals on the map. The user must respond with the exact spelling of both the city and the country as entered in the data base. (After all, you don't like it when someone misspells your name!) Case does not matter. U.S. states will be identified by their two letter postal abbreviation. Responding with END or QUIT at any prompt will take you back to the main menu. A running session score of the number of correct responses versus the number attempted is maintained. This permits the user to exit the game to study the maps some more. When you reenter the challenge your score is based upon what you did earlier in the session as well as this time. OPTION 14 Requests new DAT and LOC file names. ENTER, by itself makes no change. You must include the path if the file IS NOT in the current directory. PRINTING A MAP The creators of the operating system chose not to support the printing of GRAPHIC images within DOS. This requires an external program to be run before running the WORLD29 program. For CGA screens the supplemental disk that comes with DOS contains a program named GRAPHICS. This program is discussed in chapter 7 of the DOS manual. There are restrictions on the printers supported and options that can change the appearance of the output. The GRAPHICS program that comes with DOS version 4.01 or later supports CGA, EGA, and VGA screen prints and many printers. 33 PREPARING A WORKING DISK Neither WORLD29 nor any of its associated files are copy protected and a backup of the original disk should be created before the program is used. Creating a Backup disk Start the computer with the Disk Operating System (DOS). If you are presented with a menu of options, see your supervisor about making backups. HARD DISK If you have a hard disk and are presented with a C:> prompt or some variation of this: Place the original copy of WORLD29 in the A: drive. This is generally the Top or Left most Floppy diskette drive. Close the door on the A: drive. Find a diskette to make the copy on. This diskette will effectively be erased and any data or programs on it will be unusable once a copy of WORLD29 is placed on it. Place a label on this disk telling you that it is the BACKUP copy of WORLD29. IF YOU HAVE ONE FLOPPY DRIVE type DISKCOPY A: B: and hit enter. Don't worry, after the computer reads some of the data from the original disk it will tell you to place the second (or TARGET) disk in the drive. The computer may ask you to place the disk with COMMAND.COM on it back in the drive. That means the DOS disk. If it asks, put the DOS disk in the drive. If it asks for the SOURCE disk, it wants the Original WORLD29. If it asks for the target, it wants the BACKUP disk. When it does so, remove the original and place the disk that will be your backup in the drive and close the door. When you are ready, press the ENTER key and the computer will write what it read to the new disk. When it has finished, it MAY ask you to put the original disk (SOURCE) back in the drive. This will depend on how much memory the computer can find to work with. If it asks for the original, take the backup disk out and put the original back in the drive. Close the door and press ENTER when you are ready. Continue this process until the computer asks you if you want to copy another disk. Answer this question by pressing the N key and hitting ENTER. Remove the disks. Place the original copy of WORLD29 in a safe place. If you ever have a problem with the BACKUP copy, you can retrieve the original and follow the same procedure to make another BACKUP. 34 IF YOU HAVE TWO FLOPPY DRIVES place the BACKUP disk in the second drive, close the door, type DISKCOPY A: B: and hit enter. The computer will read the information from the A: drive and write it to the B: drive. When the computer asks if you want to copy another disk, answer by pressing N and hitting ENTER. Remove the disks. Place the original copy of WORLD29 in a safe place. If you ever have a problem with the BACKUP copy you can retrieve the original and follow the same procedure to make another BACKUP. COPY THE FILES TO THE HARD DISK. Place the BACKUP copy of WORLD29 in the A: drive. Now create a special subdirectory to keep all the files belonging to WORLD29 together. Type MD\WORLD29 and hit ENTER. This means Make a directory named WORLD29. (Notice the \ slants from upper left to lower right and you can give the subdirectory any name you want after the \) Now to get to the subdirectory type CD\WORLD29 and hit ENTER. This means Change location to the subdirectory named WORLD29. (if you used a different name be sure to type that name instead of WORLD29 after typing the \) Now type copy A:*.* and hit ENTER. This means to copy each and every file from the disk in the A: drive to the subdirectory you are now in. 35 FLOPPY DISK SYSTEM Type DIR DISKCOPY and hit Enter. If the computer does not print things that include the words "DISKCOPY.COM" and the words "1 File(s)", you will have to find the disk with the program DISKCOPY on it. This is generally the second disk that came with the DOS. IF YOU HAVE ONE FLOPPY DISK place the disk with DISKCOPY.COM on it in the drive and type DISKCOPY A: B: and hit enter. Don't worry, after the computer reads some of the data from the original disk it will tell you to place the second (or TARGET) disk in the drive. The computer may ask you to place the disk with COMMAND.COM on it back in the drive. That means the DOS disk. If it asks, put the DOS disk in the drive. If it asks for the SOURCE disk, it wants the Original WORLD29. If it asks for the target, it wants the BACKUP disk. When it does so, remove the original and place the disk that will be your original in the drive and close the door. When you are ready press the ENTER key and the computer will write what it read to the new disk. When it has finished, it MAY ask you to put the original disk (SOURCE) back in the drive. This will depend on how much memory the computer can find to work with. If it asks for the original, take the backup disk out and put the original back in the drive. Close the door and press ENTER when you are ready. Continue this process until the computer asks you if you want to copy another disk. Answer this question by pressing the N key and hitting ENTER. Remove the disks. Place the original copy of WORLD29 in a safe place. If you ever have a problem with the BACKUP copy, you can retrieve the original and follow the same procedure to make another BACKUP. IF YOU HAVE TWO FLOPPY DISKS place the disk with DISKCOPY in drive a:, the BACKUP disk in the second drive, close the door, type DISKCOPY A: B: and hit enter. The computer will read the program from the A: drive, then it will ask you to put the SOURCE disk in drive a: and the TARGET disk in drive B:. Source is the original WORLD29 and TARGET is the BACKUP disk. The computer will then read the information from the A: drive and write it to the B: drive. When the computer asks if you want to copy another disk answer by pressing N and hitting ENTER. Remove the disks. Place the original copy of WORLD29 in a safe place. If you ever have a problem with the BACKUP copy, you can retrieve the original and follow the same procedure to make another BACKUP. Use the Backup for your daily use. 36 CUSTOM CONFIGURATION Although WORLD29 is designed to be run upon receipt, you may want to change certain things to take advantage of your taste or system. These SPECIAL changes will be stored in a file called WORLD.CNF. WORLD.CNF is presently set up for operation on a computer with a CGA graphics board. It will have WORLD29 check to insure certain files are where they should be. It expects to find all TRAKSXX file in the same subdirectory as WORLD29. The colors are set the way I normally use them on a CGA. To change any of these settings the CREATOR.EXE program has been provided. This is the WORLD FILE CREATION ASSISTANT (CREATOR.EXE). It will present you with a menu of options. To change the WORLD.CNF file press W and hit ENTER (Note the capital W). MONITOR SELECTION The program will ask "Do you have CGA, EGA, or VGA ([C],E,V)? The Default answer (the answer you will get if you just hit ENTER is enclosed in the square brackets []) is C for CGA. This is used internally by CREATOR only (2.9G on) If you have a CGA or Hercules compatible system you MUST select C and hit ENTER (or just hit ENTER). The program will not function properly if you enter E ENTER or V ENTER. If you have an EGA or VGA you can type C or E or V. If limit the colors to those avaiyou select C the program will limit to colors available on a CGA. If you type E and ENTER you will maximize the capabilities of WORLD29. You will be allowed to select the colors of various line segments and display all maps optimally. If you type V and ENTER you will be running the program at the limits of its capabilities. This is, in fact, the EGA mode. The V is provided for convenience. I have experimented with VGA modes and have found that the line strength does not warrant its use. (IE. the data does not support higher resolution and the line strength is too weak) CHECK FOR FILES The program will ask "Do you want to check for the presence of correct files ([Y]N)? The Default answer is Y for Yes. I recommend only selecting N if you know that a required file is missing and that the fact that it is missing does not concern you. When you leave this answer Y, WORLD29 will check to see if certain files are where they are supposed to be. If it finds 37 something wrong, the program will give you a report when you start the program. Depending on which file is missing you will be told what to do if anything. If, for example, this file (WORLD.DOC) is missing WORLD29 will simply print a list of files that should be present. If the program cannot find the TRAKS file, it will report that fact and remind you to use option 8 to create a new TRAKS file. SPECIAL SUBDIRECTORY Since the data in the TRAKS files is in ASCII (no special characters), the file can be utilized by other programs. To facilitate the use by other programs I have provided the ability to place these files (TRAKSXX - where XX can be any legal character) in a different subdirectory. The usual location is in the same subdirectory as WORLD29. This is the default (Current) subdirectory and is chosen by simply hitting the ENTER key. If you wish to keep the TRAKSXX files in another subdirectory, type the name of the subdirectory and hit enter. NOTE: Do NOT include the first \ when typing the name) SUPPLEMENTAL FILE NAME WORLD29 can read in supplemental files that act as overlays for the appropriate maps. Two sample supplemental files are included with the program (SUP.DAT - the boundaries of the provinces of Canada and USSR.DAT - the Republics of the Soviet Union -courtesy of Brian Cook). You can create your own overlays using these files as examples. They are ASCII files and can be read by word processors or editors. The default supplemental file is SUP.DAT. If you hit ENTER, this file will be loaded each time WORLD29 is run. If you want another supplemental file, simply type its name and hit enter. If you want no supplemental file, type NONE in capitals and hit enter. COLOR SELECTION You will be prompted for a number that translates to a color that depends on your system. Unfortunately, what I call and see as yellow on my system may not be what you call and see as yellow on your system. I have provided defaults for each color that I find pleasing or useful. If you do not like my choices feel free to experiment! The first selection is for the Primary text color - default is 7 (generally white) 38 The next is for Primary background color - default is 0 (black) Color for box 1 - default 4 - recommend 0 for mono systems. Frame for box 1 - default 3 - recommend 7 for mono systems. Color for box 2 - default 4 - recommend 0 for mono systems. Frame for box 2 - default 11 - recommend 7 for mono systems. Header color box 2 -default 11 - recommend 0 for mono systems. Header frame box 2 -default 4 - 7 for mono IF YOU HAVE SELECTED C FOR A CGA SYSTEM above you will be asked "Screen 1 color pallet" the default is 0 Green, Red, Yellow 1 Cyan, Magenta, White The program will now print on the screen what you have entered for the configuration. This will also include a line of zeros. These are place holders and should be of no concern to you. It will then ask " is this ok ?" If it is the way you want it, type Y and hit ENTER. Any other response will NOT write the new WORLD.CNF file to the disk. If you respond with Y and ENTER, the program will confirm that it has written the new WORLD.CNF file to the disk. IF YOU HAVE SELECTED EITHER E FOR EGA OR V FOR VGA, you will be asked for more color selections. Each selection will include a default that can be chosen by simply hitting the ENTER key. You may enter any number between 0 and 63 for any of these selections. Each number represents a color that can be reproduced on the EGA or VGA system. You can experiment with the choices until you achieve the desired effect. Remember, if you have chosen a 0 (black) background, drawing lines in color 0 (black) will create invisible lines or erase portions of lines that are overdrawn. The program will now print on the screen what you have entered for the configuration. It will then ask " is this ok ?" If it is the way you want it, type Y and hit ENTER. Any other response will NOT write the new WORLD.CNF file to the disk. If you respond with Y and ENTER, the program will confirm that it has written the new WORLD.CNF file to the disk. 39 FILE FORMATS As discussed above, all files created by WORLD29 are ASCII files. They can be maintained, changed, or created by a vast array of editors and word processors. When using use mode EDLIN standard commands PC-WRITE standard commands (no dot commands) WORD PERFECT load with CTRL-F5, Dos Text WORDSTAR Non Document mode For any other editor check the manual for DOS or ASCII file manipulation. NOTE: in the following discussions FF represents fractional degrees (1 minute =.0167 degrees). Do not confuse this with minutes. (sng) - represents single precision numbers and (int) represents integers. CUSTOM.LOC files. Each line represents one location or record. Each element of the record must be separated by a comma ",". The format for each line is: Quoted string - Used as the location name. Number(sng) - Used as latitude.(South Hemisphere -) Number(sng) - Used as longitude.(West Hemisphere -) Number(int) - Used for display level (1-5) NOTE: The Quoted string MUST contain a ","(comma) or a " " (space). Without either a comma or space the displays will not be properly identified. Limitations: Technically the Quoted string may be up to 250 characters. Practically it should be limited to 32 characters for display in the nearest location field. When displayed in the Option 7 table it will be truncated to 19 characters. The latitude must be less than 90 degrees and greater than -90 degrees. They must be in the form DD.FF. Leading and trailing 0s are not required. Negative indicates SOUTHERN hemisphere. The longitude must be less than 180 and more than -180 degrees. It must be in the form DDD.FF. Leading and trailing 0s are not required. Negative indicates EASTERN hemisphere. The display level must be an integer from 1 to 5 inclusive. 0 is reserved for internal locations and numbers greater than 5 will not be displayed. 40 TRAKxxxx. files Each line represents one fix, position, or record. Each element of the record must be separated by a comma ",". The format for each line is: Quoted string - used as the track identifier Number(int) - used as a date identifier Number(sng) - Used as latitude.(South Hemisphere -) Number(sng) - Used as longitude.(West Hemisphere -) Number(int) - Used for display level (1-4) Limitations: Technically the quoted string is limited to 250 characters. Practically It should be small to avoid screen clutter when displayed (generally less than 20 characters) The latitude must be less than 90 degrees and greater than -90 degrees. They must be in the form DD.FF. Leading and trailing 0s are not required. Negative indicates SOUTHERN hemisphere. The longitude must be less than 180 and more than -180 degrees. It must be in the form DDD.FF. Leading and trailing 0s are not required. Negative indicates EASTERN hemisphere. The strength or confidence level must be an integer from 1 to 4 inclusive. These numbers are translated into circle diameters with 1 being the largest and 4 the smallest. SUP.DAT files The name SUP.DAT is representative of a class of files I call supplemental or OVERLAY files. These file allow you to add whatever graphic information you wish to the maps created by WORLD29. The program comes with two sample OVERLAY files: SUP.DAT, which includes the province boundaries for CANADA USSR.DAT, created by Larry Cook, the republics of the USSR The format of this file is somewhat more flexible than the others. Essentially, WORLD29 reads pairs of numbers from the OVERLAY files and deals with them on the following basis. If the NUMBER PAIR is 99,99 it is treated as a PEN UP command. Any line being drawn is ended. If the PEN IS UP and THE NUMBER PAIR IS (int),99 and int is less than 15 on an EGA or VGA system the color associated with that attribute in the WORLD.CNF file is used to color subsequent line segments. For CGA systems the int should be 3 or less. Larger numbers will be indistinguishable. 41 If the PEN IS UP and THE NUMBER PAIR is 99,99 WORLD29 ceases reading the file (This is its EOF marker - 99,99,99,99) If the NUMBER PAIR consists of (sng),(sng) and the first number is a valid latitude (90 to -90) and the second a valid longitude (180 to -180) WORLD29 will attempt to plot the point in the current color. If the PEN is UP it will be lowered and a line will be drawn from this point to the next valid point unless the PEN UP command (99,99) is received. The first (sng) will be considered a latitude, the second a longitude. NOTE: In OVERLAY files the WESTERN hemisphere is indicated by a negative (-sng). This is inconsistent with the entries made within the program and in the TRAK files. This is due to the internal manipulation of data. The number of elements on any line is not critical. Each element on any line must be separated from the next by a comma ",". It IS critical that the numbers be paired. I find it most convenient to type sequential lat and long points to a convenient line length, continue on the next line, if necessary, and end a line with the PEN UP (99,99). I isolate color changes to a single pair on a line ((int),99). This, however, is not necessary. 42 REGISTRATION Registration is buying the program! It's as simple as that. When you pay a distribution service a few dollars you have bought a disk and paid for the service to search through many many programs to find programs that are of value to their customers. The person or company that created the program receive nothing from the distributor. If you receive the program from a friend or BBS, the creator of the program again receives nothing. Shareware is like test driving an automobile. You have a 100% operational, real program to test drive! You can take the car out of the showroom and, in some cases, even take it home for a while. With shareware you can even take it to work and see if it does what you want it to do. But, until you register the program it is not yours! Once you find that you are USING the program for something, not just trying it out to see what it will do, it is your responsibility to pay for the program. That alone is enough reason to register programs but in most cases there are other benefits that accrue to those who do register. The Cost of registering a single copy of this program is $10 in U.S. funds. When you register this program you will: Be entitled to the latest update of the program on your disk for free and all future updates at $5 each. Updates will be the result of user suggestions and/or corrections. (an additional $5 handling fee if I am to supply the disk and mailer) You will receive an acknowledgement from the author and a single page summary of other programs he has written.
