The above line does not work after i save it as .bat and execute

i want to put the paragraph in a file with a unique name so that it does not overwrite any existing file. Do i need to echo at each and every line and keep appending.

You don't need to use an echo at each line if you add a `^` as the last character on each line, as per http://stackoverflow.com/questions/1015163/heredoc-for-windows-batch. — Fabian Tamp, Jan 27 '13 at 14:37

Put a unique text marker after the final EXIT /B, followed by your paragraph. Use FOR /F with FINDSTR to locate the unique marker, and then use a FOR /F loop to process all the lines after the marker.

There are many variations, each with different limitations.

Here is the simplest form, but it also has the most limitations. The limitations are described in the text.

@echo off
setlocal disableDelayedExpansion
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText" "%~f0"'
) do if not defined skip set skip=%%N
>test.txt (
  for /f "usebackq skip=%skip% delims=" %%A in ("%~f0") do echo(%%A
)
type test.txt
exit /b

:::BeginText
This text will be exactly preserved with the following limitations:

  1) Each line will be terminated by CR LF even if original has only LF.

  2) Lines are limited in length to approximately 8191 bytes.

  3) Empty lines will be stripped.

; 4) Lines beginning with ; will be stripped.

  5) The text will be truncated at the first occurance of hex code 0x1A (Ctrl-Z).

Special characters like ^ & < > | etc. do not cause a problem

Some odd FOR /F option syntax removes the limitation on lines beginning with ;

@echo off
setlocal disableDelayedExpansion
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText" "%~f0"'
) do if not defined skip set skip=%%N
>test.txt (
  for /f ^usebackq^ skip^=%skip%^ delims^=^ eol^= %%A in ("%~f0") do echo(%%A
)
type test.txt
exit /b

:::BeginText
This text will be exactly preserved with the following limitations:

  1) Each line will be terminated by CR LF even if original has only LF.

  2) Lines are limited in length to approximately 8191 bytes.

  3) Empty lines will be stripped.

  4) The text will be truncated at the first occurance of hex code 0x1A (Ctrl-Z).

Special characters like ^ & < > | etc. do not cause a problem
;Lines beginning with ; are preserved

Reading FINDSTR /N output instead of reading the file directly preserves empty lines. But a new limitation with leading : is introduced.

@echo off
setlocal disableDelayedExpansion
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText" "%~f0"'
) do if not defined skip set skip=%%N
>test.txt (
  for /f "skip=%skip% tokens=1* delims=:" %%A in (
   'findstr /n "^" "%~f0"'
  ) do echo(%%B
)
type test.txt
exit /b

:::BeginText
This text will be exactly preserved with the following limitations:

  1) Each line will be terminated by CR LF even if original has only LF.

  2) Lines are limited in length to approximately 8191 bytes.

:::  3) Leading : will be stripped from each line.

Special characters like ^ & < > | etc. do not cause a problem
Empty lines are preserved!
;Lines beginning with ; are preserved.

This final version is about as good as it gets. Delayed expansion must be toggled on and off to preserve ! that may appear in the text.

@echo off
setlocal disableDelayedExpansion
set "skip="
for /f "delims=:" %%N in (
  'findstr /x /n ":::BeginText" "%~f0"'
) do if not defined skip set skip=%%N
>test.txt (
  for /f "skip=%skip% tokens=*" %%A in (
   'findstr /n "^" "%~f0"'
  ) do (
    set "line=%%A"
    setlocal enableDelayedExpansion
    echo(!line:*:=!
    endlocal
  )
)
type test.txt
exit /b

:::BeginText
This text will be exactly preserved with the following limitations:

  1) Each line will be terminated by CR LF even if original has only LF.

  2) Lines are limited in length to approximately 8191 bytes.

Special characters like ^ & < > | etc. do not cause a problem.
Empty lines are preserved!
;Lines beginning with ; are preserved.
:::Leading : are preserved.
