Hi! Robert,

On Sun, 25 Jan 04, you wrote to me:

I wasn't sure how nested FORs worked and remembered something about
possibly having to do a...

  for %%x in (whatever) do CALL %COMSPEC% /C for %%x [whatever]...

as a workaround.  I forget the wherewithall as I don't run nested FORs to
begin with.  :)

Ahha!  Here we go.  From Jamie Hermans, posted MArch '95:

Normally, FOR-loops cannot be nested.  If they could, we could say:

  for %%f in (h H /?) do for %%g (// -) do if "%1"==(%%g%%f) goto {at}Help

It *is* possible to nest FOR loops, by using COMMAND /C...

  for %%f in (h H /?) do command /c for %%g in (// -) do if
"%1"==(%%g%%f)...

What if I refuse to run anything later that breaks NSET!?!  Jest kiddin'. 
:)  I have no hardware here capable of running better than Win95C, which
has the last bestest ever DOS, IMHO.

It's a straight-up batch solution.  No EDLIN of QBasic weirdness either. 
It was something MM came up with in a moment of pure ingenuity.  :)  He
turned out something that could apply any DOS command line against a list
of files or directories, contained in a text file listing.  I haven't tried
to use it but I'm waiting to hear from Gerry Miller, to see if it fitted
his need.

Cheers,
Paul.
