A) PURPOSE:
=â
To produce quality graphic representations of high-and-low or
median temperatures for one or more localities.
B) FEATURES:
=ä
Current temperatures are plotted against historical data on a
calendar-year or quarterly basis.
Plotted historical data can be smoothed using 3-day, 5-day or
7-day moving averages. The raw data is unaffected.
The graphs can be scaled in degrees Fahrenheit, degrees Celsius
or both at once.
Total heating degree-days and cooling degree-days are displayed
on all graphic presentations except when plotting exclusively
in degrees Celsius.
Graphs can be displayed in color, black/white-on-white or
white-on-black. The latter two options accommodate graphic
screen printing utilities such as GRAPHICS (the version that
comes with DOS 4.0, and higher), SCRNDUMP and PRTSC.
When in color, the background and ten other graphic elements
can be set to any one of sixty-four colors (including black).
Built-up databases can created for any locality. Each hastens
access to its data, particularly when a database reflects more
than five years' of historical temperatures. There can be up
to one-hundred built-up databases per locality (at the rate of
of 6K-bytes per database).
The contents of any built-up database can be viewed, saved to
a text file or sent, formatted, to an IBM- or Epson-compatible
dot matrix printer. The printout can be in either degrees
Fahrenheit or degrees Celsius -- but not both at once.
Likewise, the data for any one year for any locality can be
saved to a text file or sent to a printer.
Each built-up database can carry a unique title and footnote
- or credits line - which appears on its graph. Also, each
built-up database carries its own color information along
with a quantity of other options.
Tables listing average temperatures, extremes and degree-day
values over a period of years can be viewed and printed.
Special built-up database USERPREF.WHS furnishes the default
parameters used when creating a new built-up database. You
can choose most of those parameters by selecting "Graphic
parameters" from an Options menu. Another special file,
USER1992,WHS, is associated with this feature.
Sample data is provided under the locality name of MNOQ for
Minocqua, WI. It is intended as a learning aid.
You can erase WHIST data files from within the program itself.
There is ample protection against accidental erasure.
Just for the record, WHIST uses 640 x 350-pixel graphics.
An annual histograph is scaled in steps of one X-axis pixel
per day and 1.6 Y-axis pixels per degree Fahrenheit (2.88
pixels per degree Celsius). Quarterly graphs are scaled in
steps of four X-axis pixels per day with current-year high
temperature deviations being offset from low temperature
deviations by one pixel (so that any overlap can be seen).

C) HARDWARE REQUIREMENTS:
=æ
1) IBM PC, or equivalent, running under PC/MS-DOS 2.1 or higher.
2) Display and driver: EGA (Enhanced Graphic Adapter) or better,
with at least 256K bytes of graphic memory.
3) Minimum conventional memory: 384K bytes of available RAM.
4) Function keys F1 through F10.
5) Cursor (arrow) keys.
ü
D) NON-REQUIREMENTS:
=î
1) A hard disk (C, D, E or F) is supported, but not required.
2) A math co-processor neither supported nor required. Math
co-processor emulation is built into the program.
ü
E) LIMITS AND LIMITATIONS:
=Æ
1) Up to one-hundred thirty-three years of daily temperatures can
be processed into a single histograph. Data is not restricted
to contiguous years nor does it have to be complete for every
year in the database. At least two years' data are needed to
produce a (barely) useful histograph. This version supports
years 1795 through 2020 (according to Jeopardy, the U.S.
Weather Service was founded in 1895).
2) This facility accommodates temperatures ranging from -40 to +110
degrees Fahrenheit or -40 to +45 degrees Celsius. Unusual input
is trapped, bleeped and questioned.
3) This facility accommodates two-hundred twenty localities, disk
space permitting. The locality last selected becomes the default
locality the next time you start this program.
4) Although WHIST cannot produce hard copies of weather histographs,
other utilities, such as SCRNDUMP by Hardwood Software Associates
and PRTSC by User Friendly, Inc., can. Neither utility is included
with this package. They are not mine to distribute. I got my copies
from the Public (software) Library of Houston, Tx.
Graphics driver GRAPHICS.COM furnished with DOS version 4.0, and
higher, can print weather histographs. é ~î
~é
Going the commercial route, the SNAPSHOT/SNAP2ART utilities found
in PSF:First Publisher, version 2.0 and up, can print weather
histographs. But it takes a bit of doing.
Microsoft Windows 386 can capture and paste a weather histograph
into Paintbrush. Windows 286 can NOT capture histographs because
of 'insufficient available memory', or something like that.
5) Extended/expanded memory is not supported.
6) This facility works with calendar years and quarters. It does not
recognize seasons.

I) VERSION HISTORY - in reverse order:
=ï
3.0 A MAJOR RE-MAKE.
~ï
Re-wrote WHIST to make it more like WHIST3D, a program that
creates planer 3-D graphs from WHIST data files. See Section
J, below, for more about WHIST3D.
Annual data files shrink by 50% to less than 1K and built-up
database files by 75% to about 6K. A utility for converting
version 2.xx data files to work with this version is included.
Versions 1.x got lost by the wayside. I don't remember all
of the changes - improvements?
2.11 Version 2.10 destroyed the printout routine for daily temper-
ature values. Dang! Fixed it. Added dynamic high and low
monthly averages along with monthly heating and cooling degree-
day values to the data-entry screen. Added those same values
to the (just now fixed) printout routine. Added tables that
compare extreme and average temperatures as well as degree-days
on a monthly basis over a range of years. The new tables can
be viewed and printed, but not sent to file.
2.10 CORRECTED AN ONGOING GROSS ERROR.
Degree-days was consistently overstated by 60 percent in earlier
versions of this program! Ç ~ö
Added current and historic degree-days summations on graphic
presentations -- in Fahrenheit only. Toggle keys hide/display
them. Added the ability to hide/display the credits line on
graphic presentations. Changed "histogram" to read "histograph"
throughout the program.
2.00 Heard from Bondi Junction, NSW, Australia where Celsius is
spoken, so:- added Celsius capability (not as easy as it
sounds). Added ASCII output features and incorporated year
1991 in the sample database. Added more user options, compli-
cated the menus accordingly, streamlined certain features and
expanded the documentation. Also, arranged to recognize more
hard disk drive letters during the installation procedure.
1.12 Program recognized Ctrl-Ins and Ctrl-Del key combinations from
an AT keyboard but not a PC keyboard! Fixed it. Also expanded
upon the documentation, rearranged the main menu and made the
graphing menu a bit more user-friendly.
1.11 Fixed a debilitating file-naming error in the ORIGINATE A
LOCALITY routine.
1.1 Added the ability to display white-on-black histographs (the
original was multi-color only) in order to support various
graphics screen-dumping programs. Also, added the ability
to create a built-up database from a list of daily 'normal'
temperatures.
ü
J) PLANER 3-D HISTOGRAPHS - EGA graphics (or better) required.
=Æ ~¥
Another program, WHIST3D, can be obtained from this author. It uses
WHIST data to create planer 3-D histographs.
Key-in PLANER3D and press <Enter> to see a sample planer 3-D histograph.
