Batch modifying text.txt before a specific word - batch-file

Question

I have a file.txt where there are lines as
IF TANK T395 LEVEL ABOVE 4 THEN PUMP PFALDA395&T395 STATUS IS CLOSED
that I would like to transform in
IF TANK T395 LEVEL ABOVE 4
THEN PUMP PFALDA395&T395 STATUS IS CLOSED
I tried with this code.bat
#echo off
del "newfile.txt" 2>nul
(
for /f "eol=| usebackq for /f tokens=1,2,3,4,5,6,* delims= " %%a %%b %%c %%d %%e %%f %%g in ("oldfile.txt") do (
for /f %%h in ("%%g") do (
if /i "%%h"=="THEN" (
echo %%a %%b %%c %%d %%e %%f
echo. %%g
)
)
echo %%a %%b %%c %%d %%e %%f %%g
)
)>"newfile.txt"
I got a fast
%b non atteso (not waited)
What am I stumbling in?

Answer 1

just replace every <space>THEN<space> with <newline>THEN<space>:
#echo off
setlocal enabledelayedexpansion
REM Creating a Newline variable (the two blank lines are required!)
set NLM=^
set NL=^^^%NLM%%NLM%^%NLM%%NLM%
for /f "delims=" %%a in (t.txt) do (
set line=%%a
echo(!line: THEN =%NL%THEN !
)
(I took the creation of a NewLine from here)

Answer 2

You tried to specify variables for all tokens in the outer for command, but you must specify only the first one, which is %%a in your case; all the others (%%b, %%c,..., %%g) are defined implicitly via the tokens option (see also #Stephan's comment).
Besides that, your code outputs the original and the split line into the output file. Hence I inserted an else clause.
Finally, I implemented an additional condition: the code searches for IF as well now and splits therefore only lines which start with IF and contain THEN as the 7th token.
#echo off
del "newfile.txt" 2> nul
(
for /f "eol=| usebackq tokens=1,2,3,4,5,6,* delims= " %%a in ("oldfile.txt") do (
if /i "%%a"=="IF" (
for /f "eol=| tokens=1 delims= " %%h in ("%%g") do (
if /i "%%h"=="THEN" (
echo %%a %%b %%c %%d %%e %%f
echo %%g
) else (
echo %%a %%b %%c %%d %%e %%f %%g
)
)
) else (
echo %%a %%b %%c %%d %%e %%f %%g
)
)
) > "newfile.txt"
Edit:
The above solution can be simplified after following #Aacini's comment:
#echo off
del "newfile.txt" 2> nul
(
for /f "eol=| usebackq tokens=1-7* delims= " %%a in ("oldfile.txt") do (
if /i "%%a|%%g"=="IF|THEN" (
echo.%%a %%b %%c %%d %%e %%f
echo.%%g %%h
) else (
echo.%%a %%b %%c %%d %%e %%f %%g %%h
)
)
) > "newfile.txt"
Herein, only one for loop and one if clause is required.
