This document created with VDM.COM.
To extract files from the library *.LBR files, type
in,for example, :-
A>LT SIEVE A:*.* <cr>
NOTE: You must include the drive (even if A:) and
the *.*.
FILES ON THIS DISK:
QUIX-2.COM Graphics demos - trivial, perhaps, but I find them
fascinating, even on a green screen. Premium only.
SIEVE.PAS
SIEVE2.PAS
SIEVE.COM
SIEVE2.COM Two versions of the Sieve of Eratosthenes. The source is
there for those who don't have a compiler.
SIEVE2 is my preference.
GRAFUNCL.COM
GRAFUNCL.000 A program to plot certain types of graphs. You can alter
the variables to see how they affect the result. Can also
be used as a quick way of calculating the X Y coordinates
for plotting yourself.
This is a limited demo version.
COPI.DOC
COPI.COM Calculates the exact length of a file in bytes. Does this
as it copies the file. Don Thornton died some 6 months ago.
VDE.COM
VDM.COM
VINST.COM
VDE24USE.DQC
VDE24QRF.DQC
VDEINSTL.DQC A wordprocessor. File size is limited to available memory
which is about 40K on a Premium. I have loaded a 56K file
into VDE. VDE uses Wordstar-like commands and is quite
powerful. I find the WINDOW feature very useful as I use
VDE when programming in BASIC-E. Installation is not really
difficult. Its real usefulness is the speed with which you
can move about the file - Wordstar is s-l-o-w by comparison.
Another very useful feature is the ability to define up to
9 macros, either a defaults, or redefined for one off use.
ERUN.COM Run time interpreter for BASIC-E, a public domain BASIC
intermediate code compiler. Used to run .INT files
eg ERUN ALTAZI.
ALTAZI.INT Calculates the altitude and azimuth of stellar objects for
use with binoculars, Dobsonian and Altazimuth telescopes.
You must know the right ascension and declination of the
object and your latitude and longitude.
Azimuth bearings are calculated as EAST of North, unlike
STARFIX.BAS from SIG/M 283, which does the same job but
expresses azimuth as WEST of North.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 03E0 - 03EF }
- Longitude 0402 - 040C } initial screen only
- Latitude 0418 - 0421 }
- Place 0908 - 0925 >
- Longitude 08E5 - 08EA >
- Latitude 08F0 - 08F5 > used for calculation
- Time Zone 08FB - 0900>
JUPITER.INT The planet Jupiter has 4 moons visible in small telescopes.
JUPITER will plot their relative positions on screen for a
given starting date and period. You can print the results.
As BASIC-E has no LPRINT instruction, you must turn the
printer on or off by inputing P^P when asked.
Sometimes a strange date is shown at the end of a month if
the plot interval is less than 24hrs. However, the plot of
the moons is correct.
STARISE.INT Calculates the time and direction of rising and setting of
stellar objects of known right ascension and declination.
You must input your latitude and longitude.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 03F1 - 0400 }
- Longitude 0413 - 040D } initial screen only
- Latitude 0429 - 0432 }
- Longitude 08E8 - 08ED >
- Latitude 08F3 - 08F7 > used for calculation
- Time Zone 08FD - 08FE >
ECLIPSEL.INT
ECLIPSEG.INT Calculate the times of lunar and solar eclipses for a
particular location for a particular date range. You must
know your latitude and longitude.
Two versions are provided. ECLIPSEL calculates local times,
in this instance Eastern Australian Standard Time (EAST),
and ECLIPSEG, which shows Universal Time (UT).
Lunar eclipse times have checked out to within 5 - 6
minutes of times shown in ephemerides.
As I can find little information about detailed times of
solar eclipses at particular locations, I have not been
able to check solar eclipse results as thoroughly.
ECLIPSE does not check that the sun or moon is actually
visible at the time of eclipse. You will need to check
visibility with other programs.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
ECLIPSEG:
- Place 12BE - 12CD }
- Longitude 12E0 - 12EA } initial screen only
- Latitude 12F6 - 12FF }
- Longitude 17DD - 17E3 > used for calculation
- Latitude 17E8 - 17EC >
ECLIPSEL:
- Place 135A - 1369 }
- Longitude 137B - 1386 } initial screen only
- Latitude 1392 - 139B }
- Longitude 1884 - 1889 >
- Latitude 188F - 1893 > used for calculation
- Time Zone 1899 - 189A >
SOLEPHEM.INT Creates a Solar Ephemeris as found in an Astronomical
ephemeris.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 070A - 07A9 }
- Longitude 070C - 07C6 } initial screen only
- Latitude 07D2 - 07DB }
As SOLEPHEM uses UT (GMT) there is no need to use
variable lat, long, etc.
SUNTIMES.INT Calculates times of sunrise and sunset together with
the corresponding azimuths. Times are accurate to within
about one minute, azimuths about the same.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 00817- 0826 }
- Longitude 0839 - 0843 } initial screen only
- Latitude 084F - 0858 }
- Longitude 0CDA - 0CE0 >
- Latitude 0CE6 - 0CEA > used for calculation
- Time Zone 0CF0 - 0CF2 >
- Place 0CF8 - 0D05 >
SUNPOSN.INT Calculates the true and apparent geocentric ecliptic
longitude of the Sun and corresponding right ascension
and declination coordinates, or to put it more simply,
it just tells you where the sun is at a particular date
and time.
Given the weather in April 1990, this might be a VERY
useful program indeed.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 0794 - 07A3 }
- Longitude 07B6 - 07C0 } initial screen only
- Latitude 07CC - 07D5 }
- Longitude 0CAD - 0CB3 >
- Latitude 0CB9 - 0CBD > used for calculation
- Time Zone 0CCB - 0CD8 >
- Place 09A6 - 09B3 >
MOONPHAZ.INT Calculates date and time of new and full moons closest
to a nominated date. Accuracy is to within two minutes
or so.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 05B9 - 05C8 }
- Longitude 05DB - 05E5 } initial screen only
- Latitude 05F1 - 05FA }
- Longitude ---- - ---- >
- Latitude ---- - ---- > used for calculation
- Time Zone 099E - 09A0 >
- Place 09A6 - 09B3 >
MOONTIMZ.INT Calculates the times of rising and setting of the Moon
and the corresponding azimuths. The times are accurate
to within about 5 minutes of those in the Astronomical
Society of NSW ephemeris.
This should be adequate for most purposes.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 0D65 - 0D74 }
- Longitude 0D87 - 0D91 } initial screen only
- Latitude 0D9D - 0DA6 }
- Longitude 127D - 1283 >
- Latitude 1289 - 128E > used for calculation
- Time Zone 1294 - 1296 >
- Place 129C - 12A9 >
MOONPOS.INT Calculates the apparent geocentric position of the
Moon for a given date and time. Accuracy is very high,
to within a few arcseconds. However, the calculations
are complicated, and a little slow compared to the other
programs.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 0FB4 - 0FC3 }
- Longitude 0FD6 - 0FE0 } initial screen only
- Latitude 0FEC - 0FF5 }
- Longitude 1499 - 149F >
- Latitude 14A5 - 14AA > used for calculation
- Time Zone 14B0 - 14B5 >
- Place 14C3 - 14D0 >
PLANETS2.INT Gives the geocentric positions of any of the eight
major planets. PLANETS2 is most accurate closest to
1.1.1984, but the progressive errors are so small as
to be insignificant for most purposes.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 16F2 - 1701 }
- Longitude 1714 - 171E } initial screen only
- Latitude 172A - 1733 }
- Longitude 1B7B - 1B81 >
- Latitude 1B87 - 1B8B > used for calculation
- Time Zone 1B91 - 1B93 >
- Place 1B99 - 1BA6 >
TIMES.INC Converts between solar and siderial times, and for a
given date, shows local and Grenwich solar and siderial
times. Accuracy is to within a few seconds.
To permanently alter the location constants in the program
use DISKPCH2.COM on this disk. The areas to change are:
- Place 03E5 - 03F4 }
- Longitude 0407 - 0411 } initial screen only
- Latitude 041D - 0426 }
- Longitude 084D - 0853 >
- Latitude 0859 - 085D > used for calculation
- Time Zone 0863 - 0865 >
- Place - sorry, you'll have to work it out, its just
after the time zone.
DISKPCH2.COM On my 256TC, DISKPCH2 doesn't reboot the SHELL so I load
it from CCP.
The program is very easy to use. For those who are not
sure, I suggest you get an experienced friend to show
you how to use it.
If you want instructions, here they are:
- COPY DISKPCH2 AND THE PROGRAM ONTO ANOTHER DISK, AND
WORK ON THAT DISK.
- select F for file
- enter filename
- enter S for search
" for alpha string
PEMB for a string to search for
- enter E to edit
^A to go to the alpha side of the display
- use the cursor keys to goto the address you want
and type the new information over the old
- enter ^Q when you have made all the alterations
needed on the current screen
- enter W or A to write the current record or to abort
- you can then use + or - to scroll through the file
or search for the next string to change
- when finished Q takes you to the main menu
- enter Q at main menu to quit.
The instructions may be a bit terse, but they will get
you started. Just experiment, DISKPCH2, as I call it,
is fairly foolproof, and easy to use.
I am working on more astronomy programs, some of which may be of use to
those of us who are not expert astronomers, and which may obviate the
need to buy an Astronomical Ephemeris. I will pass them on when I think
they are bug free.
If anyone finds any problems with the programs above, please contact me
at RMB PEMBROOKE RD, PEMBROOKE, NSW 2446 (065) 859 264 (ah). I would be
interested to hear from anyone who has any good CP/M astronomy programs
they might like to pass on, or who can tell me where to find them.
