Hi
Here goes my problem. Im using a code that i got from another post to delete the last line in a text file if it founds a string.(lets call this code batch2)
set zfn=myfile.txt
set zsp=nº50
set ztf=z
:temploop
set ztf=%ztf%b
if exist %temp%\%ztf%* goto temploop
set ztf=%temp%\%ztf%
for /f "delims=[]" %%i in ('find /n "%zsp%" ^<%zfn%') do set zln=%%i
echo %zln%d>%ztf%a
echo e>>%ztf%a
edlin %zfn% <%ztf%a >nul
if exist %ztf%* del %ztf%*
for %%i in (ztf zln zfn zsp) do set %%i=
goto :eof
But i have utilitie batch (lets call batch1) file so what i want is that my batch file (batch1) make batch2 and than executed. I tried to do like Ex:echo set zsp=nº50 >>batch2 and that worked but with 2 problems:
In this line "if exist %temp%\%ztf%* goto temploop " in batch1 , when it makes batch2 it will put there my temp folder path becouse of the system variable and i want "if exist %temp%\%ztf%* goto temploop ".(exactly the same)
The other problem are 2 lines: "echo %zln%d>%ztf%a " and "echo e>>%ztf%a " becouse of the doble echo i think .
What i want is that batch1 to make batch2 exactly the same.
Sorry for my English and i hope you guys understand what i need.
Thanx

Sorry this took so long, I was busy elsewhere, then wanted to stip the VBscript out and insert DOS to test and make sure the DOS secial characters you used would not mess it up (they didn't).
The MS-DOS DIFF command on what this wrote on my Windows 2000 PC says it's the same as what I copied from above, with only a couple comments added at top and bottom.

for %%i in (ztf zln zfn zsp) do set %%i=
goto :eof
::END BATCH2.BAT If you include a "goto :EOF" you may start a BATCH 3 or more.
:EOF
sorry, i'm not tracking.
I just cut and pasted that from here to my XP Home (putting a pause before the execute) and compared the batch file created - that part worked. I tacked this clippet at the start of BATCH 2 and it did show me the batch2 file as it should, indicating it is launching the temp file:
.
.
.
::START OF BATCH FILE 2.BAT
echo.
echo.
echo bat2:
type "%~f0"
echo.
pause
goto :EOF
set zfn=myfile.txt
.
.
.
Can you be more specific as to what it is not doing? or fill in the part between :start and %zcall% ?

IF BATCH 2 IS A SET THING i mean if it is always going to be the same
save it as a text file and add this to you batch one
keep in mined the "type" below is a command
type batch2.txt>batch2.bat
call batch2.bat
here is what im confused about
if it is (im assuming by your origional post) always going to do the same thing why not just make it and be done with it
is the creation of the batch 2 conditionsal on something
if you are wanting the batch file to repeat once
you can do
(myif lf lines arent that good someone might help here)
your batch might look like this
try it and let me know
::beginningbatch
set zfn=myfile.txt
set zsp=nº50
set ztf=z
:temploop
set ztf=%ztf%b
if exist %temp%\%ztf%* goto temploop
set ztf=%temp%\%ztf%
for /f "delims=[]" %%i in ('find /n "%zsp%" ^<%zfn%') do set zln=%%i
echo %zln%d>%ztf%a
echo e>>%ztf%a
edlin %zfn% <%ztf%a >nul
if exist %ztf%* del %ztf%*
for %%i in (ztf zln zfn zsp) do set %%i=
::im confused what this line is supposed to do did you leave something out
::goto :eof
::this line should check to see if this command was executed already if so the batch has already done and
::should end
if exist batch2.bat goto end1
type 12.bat>batch2.bat
call batch2.bat
:end1
del batch2.bat
exit
by the way the goto :eof line i remarked becauseit cancels the batch because it has no command
but otherwise this works i tested it
thanks tnkr,
Nothing left out,
:EOF is a special label that is automatically goes to the End Of File for NT/XP/2K systems. Sometimes I put one there to allow the same thing to work in earlier DOS, but when I've already ruled out earlier DOS by using commands that don't work there it looks odd to also put in a :EOF with nothing after. (personal preference overrides, of course)

Two or more possibilities:
You could isolate bat2 as is and have batch1 run itself through a filter into batch2. I've got a demo of that here somewhere, . . .
Or you could use ^ to escape the special characters, like you did with ^< in the FOR /F to get < into the IN (' ... ' )
This gets prticularly messy when escaping the ^ itself with ^^ as well as the < after it though.
Have you considered using CALL to a label instead? Any time you CALL a label it acts as if the currently running program is a new program starting at that label
Good Luck,
