SET "space= "
echo %space% > temp.txt
echo testing >> temp.txt
echo %space% >> temp.txt

You can use a subtle capability of the ECHO command to get around that.  Try this test:

SET "space= "
echo.%space% > temp.txt
echo.testing >> temp.txt
echo.%space% >> temp.txt
echo.123 >> temp.txt

Open in new window

Using the "echo." followed by text, variable or nothing works perfectly and is a nice general purpose solution. Thanks a lot.
