(alt.msdos.batch.nt added and followups redirected)

@echo off & setlocal enableextensions enabledelayedexpansion
set source=C:\_M\MyData.txt
set flagStart=
set flagEnd=
for /f %%a in ('type "%source%"') do (
echo %%a|find "START-OF-DATA">nul
if !errorlevel! EQU 0 set flagStart=true
echo %%a|find "END-OF-DATA">nul
if !errorlevel! EQU 0 set flagEnd=true
if defined flagStart if not defined FlagEnd (
echo %%a|find /v "START-OF-DATA"
)
)
endlocal & goto :EOF

The output
C:\_D\TEST>cmdfaq
asdfasdfg
asdfgdfgsfg
sadfsdfgsa
asdfgsdfg

All the best, Timo
