Editors
MS-DOS Edit. This editor shows (not converts) a single TAB (ASCII 9) as
spaces. Looks as space: ASCII values: 0, 32 and 255.
Notepad shows the following characters as a single space: ASCII values:
0, 32 and 160.
Some values (ASCII 1 and other characters), can't be written [Alt+num]:
Use [Ctrl+P] [Alt+num].
ASCII 0: Can't be written with [Alt+0] or [Ctrl+P] [Alt+0]:
Use [Ctrl+@].
ASCII 9: Can't be written with [Ctrl+I] or [Alt+9]:
Use [Ctrl+P] [Ctrl+I] or [Ctrl+P] [Alt+9].
Hyper text markup language
Problems exist about ASCII value: 0.
Characters, which looks like
a space: 32 160 173.
a rectangle: 1;8 11;12 14;31 127 129 141 143;144 157.

About the SET command and how to perform a test on a special syntax
"SET;Variable=something" would be the same as
"SET Variable=something" (see the space between the SET and the Variable).
The first example above, would be something like this:
SET Chr=;
SET%Chr%Variable=something
Anyhow, just because a semicolon maybe between the SET and the Variable
doesn't mean that any character can be set to a variable named Chr.
The characters that can be used, range [001;255], [01;FF hex], are:
Dec: 09 10 32 44 58 59 61
Hex: 09 0A 20 2C 3A 3B 3D
Chr: TAB LF , : ; =
Notes: I tested this on Win98 and DOS 6.22 successful
except the colon (3A) which can't be used on old DOS.
How did I figured out of that?
The following batch file produces all the hex numbers
between and including 07 until 0C (see line 5 below:)
05 SET D=::|%COMSPEC%/E:2048/C%0 07 0C ## ::
: Number of "#" must match number of digits on both the 'items', 7 and C.
Between the below two lines is the program which used
the numbers to make a file named ~.tmp
22 IF ::==%D% GOTO EOF -----------------------------
34 IF %2==%6 EXIT. ---------------------------------
The ~.tmp file contents the hex number without CR-LF,
which goes to a file named ~.txt.
If the "SET t=!" is possible with a character such as
a semicolon between T and t, then !=%t% must be true.
@echo off %[Line number 15 maybe WRAPPED]%

if not !!==%t%! echo.~..>> %temp%.\~.txt
set t=
if %2==%6 exit. ------------------------------------
:EOF
If you remove the line:
if not %d%'==' echo.~%6~Not used..>>%temp%.\~.txt
along with all lines between ... eof ------------
and the line ... exit ---------------------------
then you'll get the first module, which I used to
make any number. Lines with a left margin are add
or modified. The program can easily be changed to
perform a test on another syntax, @prompt e0 etc.
Well, I never finished this one, hmmm.
@Super-loop:
The number of running through was 65025 so, I wanted to develop a loop,
which should be very much faster. The number of loops / running through
was for each number in the range of 7 through 22. I also calculated the
heighest frequency to 18 and an average of 17 (16.8). I executed my new
Super-loop and I used all the numbers in the range of 1 throughout 255.

I will in the future, create more examples about how to
create batch, (instead of just creating programs). This
doesn't means that I will delete my Homepage, but since
programmers makes their own programs, then I think this
is more useful than uploading my own/new constructions.

Notes about delimiters
Depending on the program and your solution, the variable V2: (see above)
would probably be used in a case as ECHO ( 210 121 212 ) | FIND " 21 "
An ASCII 255. It seems that the elements are NOT connected but they are.
An ASCII 7 as delimiter. If the data are present to the console, then it
seems that the elements are connected together as one data element. This
is true for DOS but an ASCII 7 chr would actually distinct each element.
An ASCII 32 [SPACE], simply distinct each element in the specified list.
