To do an operation on multiple files in a WinXP DOS batch:

Just a small caveat to the reader, this works within a batch file by
escaping the variable ("%A" in this case). If you're running it from
the command-line, you don't escape it, and thus use
for %a in (*.txt) do [command using %a]
instead of
for %%a in (*.txt) do [command using %%a]
Then again, maybe I'm among the freakish few that actually use for-loops
at the dos-prompt. :)

I have used them too, starting (in my case) with Dos 3.1. Your warning
is valid on old DOS shells, and is regarded as "good form" writing by
old hands like me, but IIRC, with "modern" versions of CMD.EXE, and with
NDOS.EXE, 4DOS.EXE or 4NT.EXE, you may use either %a or %%a in either
the command line or a batch file.
