Code Practice Utility
G.G.Rajendra Kumar VU2ZAP
Dedicated to all the OLD TIMERS of Bangalore
This program may not run perfectly on some Graphic
adaptors. This utility requires the keyboard to be configured
as US type. All features except keyboard send will function on
other keyboard formats. If you wish to run Code Practice from
a floppy make sure the write protect is removed from diskette.
NEW VERSION 2.00 :
This version of Code Practice incorporates new features
with larger menus. Shell feature and capability of running dos
commands from within the utility adds more versatality. Run
parameters can be changed and hide can be toggled during send.
EGA/VGA users can set 50/43/35 lines per screen. Colors can be
changed to suit your taste.
ABOUT CODE PRACTICE :
This utility (CP) generates code for skill enhancement
of the radio amateur. Not intended for the beginner as we feel
that the initial character learning should be done under under
the guidance of an experienced amateur. We must add that NEVER
learn morse in graphic DOT and DASH format. Improperly learnt
code is very difficult to correct later. However a seperate
menu is provided for the beginner, this format is the way we
teach morse here.
The program comes with the following files
2. CP.DOC (This file)
If the diskette contains a file CP.INI, please delete
the file. The program will create its own file on calibration
If any file is missing write to the Author for the
complete diskette of the latest version. Please enclose a 48 TPI
5.25" diskette, a return disk mailer packet and sufficient post-
age for its return.
CP is a user friendly utility. Its screen is menu-driven
with a help line.

and extension. All unknown characters will not be sent, but
replaced with a word space. Press any key to EXIT.
In addition to the standard characters the following may be
used in any ASCII text file for Test or Teaching :
$ = SK ...-.-* = AS .-...
! = BK -...-.-& = ES ....
@ = AR .-.-.# = KN -.--.
^ = AA .-.-

6. CP measures the time it takes to send the standard word PARIS
5 times at 20 WPM and then computes the appropriate value of
calibration constant for your machine. Run this till you can
no further improve the calibration. The display will show the
time it took in ( Seconds X one hundred ) value, and also the
calibration constant. Time should be 1500/100 secs. After the
calibration process SAVE the settings. Some resident programs
will slow down the machine, recalibrate if you make any major
changes to your Config.sys or Autoexec.bat.
7. Run a dos command from within the code practice utility
All valid dos commands or utilities can be used. Press
any key to return to code practice screen.
8. Dos command shell from within the code practice utility
Any other program can be run without changes to this
utilty. Type EXIT to return to the program.

10. Return to main menu
11. QUIT - exit code practice
The groups of characters are sent at random 5 in a group.
Characters are learnt by watching the groups appear on the screen
and associating the sounds with each character. Start at the top
with EISH5 group and progress downwards as you master each group
We suggest you start with the CODE SPEED at 15 and SPACING at 4
or 5, this way you will learn the characters at a faster speed
with enough time between characters and words to interpret the
sound heard. As you progress, increase the spacing values. When
you are through with the nine groups, graduate to the main menu
and use the ALL mode. If you are weak with any characters, go
back to CODE menu and repeat that group till you have mastered
Press ESC to go to Main menu.
NOTE : Since calibration is referenced to the standard word
"PARIS", actual speed may vary depending on the type
of characters present in a set of groups being sent.
Always be prepared to copy at a higher speed if you
are upgrading or working towards a new license.
F1. Help on menu.
F3.F4. Increase or decrease speed from a minimum of 4 to a
maximum of 50 WPM (scale displayed will be relevant
only after calibration). Speed and spacings will be
F5.F6. Increase or Decrease the spacing between characters
and words. You can increase the space between
characters by decreasing the character spacing speed.
Useful in improving your speed by giving you more time
to write the characters down on paper.
F7.F8 Increase or Decrease the weight. The figure displayed
is the ratio of DAH to DIT. Old timers might find it
nostalgic to set a ratio of 5. The code will sound like
it is being sent on a ` BUG ' key !. Standard = 3.
Minimum is 1 and maximum is 6.
F9.F10. Increase or Decrease the frequency of the tone being
sent. The default value is 700 and the value displayed
is in Hertz. Minimum is 400 and maximum is 1200 Hertz.
Change to suit your taste and SAVE setting before you
QUIT the program.

Use only keyboard number keys. If you use a monochrome monitor
try the colors and see if you like inverted black on white.

CP creates a file named CP.INI, CP.INI can be placed in the PATH
or in any directory defined by SET INIT=c:\[directory] in the
CP.EXE searches the environment first for INIT defined directory
and if unsuccessful searches the path for CP.INI. If this fails
it will create a new CP.INI file in the current directory after
Program written and compiled in QuickC 2.0 and MASM 5.1
