This should do what you want:

for %a in (*.jpg) do rem>%{at}name[%a].txt

It makes a 0-byte file for each .jpg file.

for %a in (*.*) do ren %a %{at}upper[%a]

 DD> I'm running Warp 4 with 4OS2/32 Version 2.5 and 4DOS Ver 4.02.

These work with the 6.01 (the latest version?). I'm not sure if
they work with 4.02.
