echo %stringy% > temporar.yhi
copy %dfile% temporar.yh3
REM If on Windows XP, you can just use "type %dfile% temporar" etc., but on
REM older operating systems, "type" can't use more than one file, so you need
REM to use my ANDD program instead, so if ANDD is in the EXE search path
REM named "a.bat", you can instead use "call a type %dfile% and type
REM temporar.yhi {key above period} temporar.yh2".  If you try to use the XP format on an older
REM operating system, it will accidentally delete %dfile%.  The only way to
REM stop this accidental deletion is to check to make sure temporar.yh2 is
REM larger than 0 bytes, or to scan for errorlevel after the "type" command is
REM issued.  Unfortunately, I don't know errorlevel codes and (to my knowledge)
REM you can't perform "if" relative to filesize.  This version uses "a.bat", but
REM a version that required XP but not "a.bat" could easily be made by changing
REM the line below.
REM I have taken another precaution by precopying %dfile% to temporar.yh3 (see
REM line above this bunch of REM's).
REM type %dfile% temporar.yhi > temporar.yh2
REM Update: it doesn't work to use ANDD in this program, but fortunately there is
REM another way: simply do `"copy "a.txt"+"B.txt" "3.txt"'.
