How to position echo output of variables
Batch Newbie
4.0):
1. Assign a start position of an echo variable variable
2. Assign the end position of an echo variable variable
For example:
@echo off
set var1=hello
set var2=world
echo %var1% %var2%
The result is:
hello world
What if I wanted var1 to start on the 5th space and var2 to start on
the 15th.
Example:
hello world
...............
5th 15th character
Or how to set var1's last character to end on the 10th space and
var2's last character to end on the 20th.
Example:
hello world
....................
10th 20th character
Thanks!

See if this gives you an idea
@echo off
set var1=hello
(set var1= %var1%)
set var1=%var1:~-10%
set var2=world
(set var2= %var2%)
set var2=%var2:~-10%
echo %var1%%var2%

I'm sorry foxidrive, NT4 doesn't know the minus variant. You will have to
get the length and do math.
OTOH there are 3rd party tools to do positioning:
wbat from Horst Schaeffer, http://home.mnet-online.de/horst.muc/
and
conset/conutils from Frank P. Westlake http://gearbox.maem.umr.edu/fwu/

The code seems great.. but it doesn't seem to work on Windows NT 4.0.
Perhaps I'm missing something. I know it's easily done with third
party tools. I've download some and and have working test batch
files. But I'm just curious if it can be done with pure batch or even
wsh enhanced batch files.
Thanks!

You can also use an included program to position (colored) text on
the screen:

Phil's batch doesn't work due to the usage of delayed expansion (!),
which was introduced with win2000.
Change line 07 to :
call set "var%%a= %%var%%a%%"

get the following results:
C:\>space.bat
!var1! !var2!
C:\>set var
var1= !var1!
var2= !var2!
The spacing seems off (probably just a matter of adjusting the
numbers). But the variables Hello World aren't being set. The
variables aren't being set properly on step 7 (at least on WinNT).

Matthias addendum to Phil's coding seems to be working great. I'll
need more time to figure out what all the codes mean and why it
actually does what it does :)
Hey Herbert.. I noticed several of your posts and like the idea of
creating a temporary application through echoing. Is there a site
with source of programs that can be echoed? Or how you obtaining the
code of a program in order to create it through echo? For example..
lets say I want to echo choice.exe ? I know it's not as simple as
popping in an executable into a text editor and then placing echo in
the front of each line and >name.exe on the first line and >>name.exe
in subsequent lines.
Thanks!

It is only useful to include small executables (a few hundred bytes)
within a batch. I think choice.com (5 kbyte) is much to large.
If you want to include a com file and only have the binary, you can use
Laura's cm3 utility:
>Assemble .COM file using MASM6+ and convert .COM file
>to ascii-code using my CM3 utility ( http://lf.8k.com/TOOLS )
If you have the source code, you can also use:
ftp://137.193.64.130/pub/assembler/ube.zip
You can include any binary (not only com programs) if you use a
hex2bin converter and include a hex dump of the binary:

If the binary is smaller than about 40 kbyte, you can also include
a com file which, when executed, generates the binary file:

The second for iterates from 1 to 4 to add that number of spaces.
Delayed expansion or the use of a call is neccesary to to evaluate
the vars in a specific order.
set var%%a= !var%%a!
The percent vars evaluated first giving,
set var1= !var1!
set var2= !var2!
then the ! vars follow, this way adding a space on each turn of the
inner for.
The call with help of doubled percent signs work similar. To escape
a percent sign you have to double it. The call causes the line to be
evaluated twice, at first run inserting values for %%a and changing
the doubled percent to a single one. So
call set var%%a= %%var%%a%%
gets:
set var1= %var1%
This use of call is AFAIK undocumented and works in combination with
the for set commands.

Upon further testing (figured out what the for statements does).. the
Phil's code with Matthias' contribution only pads spaces in front of
the variables and doesn't actually make the variables start at a
predetermined position (or end at a predetermined position.
01. @echo off
02. setlocal
03. set var1=hello
04. set var2=world
05. for /l %%a in (1,1,2) do (
06. for /l %%b in (1,1,5) do (
07. call set "var%%a= %%var%%a%%"
08. )
09. )
10. echo 123456789012345678901234567890
11. echo %var1%%var2%
Result is:
C:>space.bat
123456789012345678901234567890
hello world
Hello ends at position 10 and world ends at position 20. However,
this is only true if var1 and var2 is only 5 characters long (since it
is just padding). If it they are shorter or longer than 5 characters
then it is broken.
I've experimented with Herbert's ctext.com program. Looks great but
it appears to just assign starting positions of variables and not
ending positions.
I feel tears coming down :)

with a HEX dump both gif files take up 908 bytes in the batch files
using yenc they would take up 557 bytes
it cuts the size by 40%

You missed the point. If there is a binary channel so you can
transfer the decoder program (uuencode, mime or yenc) then
you also can transfer the binary gif the same way, no need to
encode it at all. But if you don't have such a binary channel,
then you have to transfer the decoder program also with the ascii
channel. And then it makes more sense to use a simple encoding
to get a small decoder because you have to minimize the sum
of the decoder size + the encoded gif size.
