THE WORLD
Version 2.0
Instructions
A file named "CUSTOM.LOC" is automaticaly read when the program |
loads. If "CUSTOM.LOC" does not exist in the current directory |
an error will occur. You can add any locations you want on your |
world map. Use your favorite ASCII editor to add NAME,LAT,LONG |
for any place in the world. A sample is included and the file |
must be named "CUSTOM.LOC" to become a full part of WORLD V2.0 |
The main menu displays as follows:
1 - Select by LAT and LONG
2 - Select by large area NAME
3 - Select by area of EUROPE
4 - Find using CITY or COUNTRY name |
5 - Capitals of the USA
6 - Other CITIES of note
7 - NATIONAL CAPITALS
8 - Eneter new info on Hurricanes
9 - The GLOBAL view |
10- Point at a location
11- Approximate distance between two Cities |
99- Exit
?
1.
Lat & Long:
If you have the latitude and longitude you want to look
at, choose option 1. You will be asked for latitude first
then longitude. Do not enter minutes and seconds.
However, you are permitted to enter decimal parts of
a degree.
The program then asks for a scaling factor (a number from
one to five). A default scale of 3 is selected by pressing
the enter key. The largest area is 1 and the most detailed
is 5.
You will then be asked if you want hurricane tracks (tracks of |
sample hurricanes are included as file "TRACKS" and "TRAKSXX). |
XX is the year of the file. "TRACKS" is the current file. |
TRAKS85 is the history or storms in 1985. No is the default. |
Hitting "y" will read TRAKS. |
The bottom center will show a horizontal line which indicates 100 |
miles at the center latitude or the map shown. |
The upper right corner of the screen will show the number of
miles in one degree at the latitude of the center of the map
being viewed.
For scales of less than 3, the names of all national capitals |
within the area displayed and a small circle identifying each |
capital will appear at the appropriate coordinates. |
2.& 3.
Area :
Selected areas of the world, especially the USA, are
presented in a list. Choose by typing the capitalized
letters for your desired area (don't use the lowercase
letters ie. S.AM for S.AMerica). Scaling is handled by the
program and the upper right corner of the screen displays
the number of miles per degree at the center lat.
4.
City finder: |
Type in the name of any city or a combination of letters and |
WORLD V2.0 will search its Data Base (and CUSTOM.LOC ) for the |
combination of letters you have entered. It will then tell you |
what it found and ask: |
"[W]orld, Area map, Select again or Look some more" |
W is the default and centers a global view on the city |
A centers an small area map on the city chosen |
S sends you back to reenter a name |
L continues the search for another match |
When no more matches are found WORLD V2.0 will say |
"I can't identify that !" and send you back to the main menu. |
5.
State capitals:
State capitals are presented alphabetically and selected by |
number. You are then asked for a scaling factor as in item |
#1 and whether you want hurricane tracks. |
Again the lower center presents the 100 mile scale, the upper |
right the miles per degree at the lat of the capital you |
have selected. (on the map any state or national capitals within |
the area you have chosen will be displayed.) |
The lower left of the screen shows the name of the capital
that the map is centered upon. The capital is marked with a
small circle. Its lat is shown at the right side center and
long at the bottom center.
6.
Other cities:
Selected (at my whim) cities are displayed alphabetically and
allow selection by number. Scaling factors and hurricane
track questions are as in #1. 100 mile indicator, miles per
degree and national caps are as above. the name of the city
and its lat and long. are also displayed.
7.
National capitals:
Over 150 randomly selected national capitals are displayed in |
alphabetical order on several pages. Select by number. 999 for
additional pages. As in previous options scale and hurricane
requests are asked for. The 100 mile line, miles per degree,
center location and other visible capitals are displayed as above.
8.
Hurricane data:
Allows you to keep track of future Atlantic or Pacific |
hurricanes. It asks the storm's name first, then date in mmdd
form, then type of storm (Hurricane tropical Storm tropical
Depresion), then lat and long. It will then ask if you have
data on other storms (default is no). Next the program asks if
you want the display of hurricane data. If you respond "y"
then a display will be generated centered upon your last
storm data with a 100 mile radius circle around it.
all appropriate data will be displayed as above.
This is an ASCII file and can be maintained by an editor. |
If you are tracking more than one storm at a time the track |
plot of the storm will be discontinuous. Use your editor or a |
sort program to keep each storm together. |
9.
Global view: |
Asks for a lat and long of the point you want at the center |
of the screen. If you default Lat and Long WORLD V2.0 does |
its best to center the world on whatever you had selected |
last in any of the available views. If in doubt just hit |
ENTER whenever these two questions showup -- the worst that |
will happen is that the center of the screen will be at |
0 degrees north 0 degrees west. |
WORLD V2.0 now asks for a Magnification factor. 1 will show |
the entire hemisphere and will include lines of Lat and Long |
at 10 degree intervals. Numbers larger than 5 will work but |
there will be long periods when nothing seems to be happening. |
Actually each point on the globe and the line between them |
is being calculated. There is no guarantee that any line will |
show up on your screen. Even 3 is starting to stretch things |
so have fun. The cursor will appear --- eventually. ENTER is |
a bail out at any time in the draw sequence. |
DO YOU WANT HURRICANES? Default =N. |
Y brings a list of track files on the default directory |
<TRAKS> or TRAKSXX. |
Default is TRAKS (current year storms). Type TRAKS85 for 1985 |
storms. This will do the plotting in 320 mode instead of 640 mode. |
The lines will be blocky but in color to indicate whether the track |
is a DEPRESSION, STORM, or HURRICANE. |
Want State boundaries? Default is n. If y is selected, WORLD V2.0 |
will include state borders with a slight slowdown in completing |
the world. |
Take the Default to save time when looking at the far east. |
10.
Pointer:
A mercator type projection of the world is displayed
with a pointer located in the Atlantic Ocean. Use your
cursor or number keys to position the cursor at the location
you desire to examine. As the cursor moves its lat and long
will be indicated. When it is near where you want it, hit the
enter key and the cursor will become the center of an
expanded view. You can now reposition the cursor and expand
again by hitting enter. Including the full world map you
have five expansions. Expansion beyond the fifth level
returns the world map. Hitting the "e" key at any level
returns you to the menu.
After a few expansions the Names and locations of visible cities |
will be plotted. |
11.
Distance calculator:
Enter cities as above and approximate great circle distance will |
be displayed. |
99.
EXIT:
provides a graceful exit to dos from the main menu.
General
Most inputs have a default. If not specified on the screen the
program will use your last response to a specific request.
You can generally default from one display to another without
changing lat & long. You will note the absence of Country boundaries
in all except north & cent America and western Europe. Adding
them will slow down processing
Don't worry about upper or lower case for your input WORLD V2.0 |
changes the keyboard case to meet its needs. Occasionally you |
will note a change between upper and lower case. Keep your fingers |
off the CAPS LOCK key and WORLD V2.0 will be happy. |
Major changes between WORLD and WORLD V2.0 are indicated by | in |
the right hand margin of this document. |
