Hello everyone.

I've got a huge list of post codes that havent got any spaces in them. there are 2 formats, for example

A12 3BC or A1 2BC so ideally I need something that will add a space 3 characters from the end of each line. The list has been put in notepad which caused problems viewing it from the START. Its a very big list.
WOULD be very grateful if anyone can help.

ThanksAre all the lines 5 letters? If so it would be much easyer.

Untested:
Code: [Select]@echo off
setlocal EnableDelayedExpansion
for /f "delims=" %%A in ('type "a.txt"') do call :loop
exit /b

:loop
set a=0
set line=%1
set char=0

:loop.1
REM find char in line
if not "!line:~%a%,1!"=="" (
set /a char+=1
set /a a+=1
goto :loop.1 )

REM find 3 spaces back
set /a end=%char%-3

set a=0
set line2=
:loop.2
REM set line2
set workingChar=!line:~%a%,1!
if %a% == %end% (
set line2=%line2% %workingChar%
) else (
set line2=%line2%%workingChar%
)
if not %a% == %char% goto :loop.2
echo %line2% >>file2.txt
goto :eof
Lemonilla, you don't ever pass the contents off to the loop.

@OP, try this:

Code: [Select]@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%a in (a.txt) do (
set line=%%a
set line=!line: =!
set line=!line:~0,-3! !line:~-3!
echo !line!>>newpost.txt
)
It removes any spaces from each line, then takes EVERYTHING but the last 3 characters, ADDS a space, then tacks on the last 3 characters to the end. It's all put into a new file called "newpost.txt".
