need help! need a batch script to delete certain data from a .c file

Funny, I did something almost exactly the same, but I was away from my computer for an extended period.

The code below iterates what you are wanting. You can either use this or Squashman's code (use in place of the second FOR loop in mine) and it should give you the results that you are looking for.

Code: [Select]

@echo off
setlocal enabledelayedexpansion
set switch=0

for /f "delims=" %%A in ('dir /s /b *.c') do (
  for /f "delims=^( tokens=1*" %%B in (%%A) do (
    if !switch! equ 0 (
      if "%%B"=="ROM_START" (set switch=1)
      echo %%B^(%%C >>temp.txt
    )
    if !switch! equ 1 (
      if "%%B"=="ROM_END" (
        set switch=0
        echo ROM_END >> temp.txt
      )
    )
  echo del %%A
  echo ren temp.txt %%~nxA
  )
)
Same rules as above with the removing the echo and adding move if needed. Let us know how this works.

Thank you raven and squashman for all your help
