.bat files are actually text files which are input to cmd.exe

Yeah, I know what they *are*. (I cut my teeth on PC-DOS 3.3, so I've written a couple of batch files. I once joked about writing interactive fiction as a series of DOS3 batch files for an abuse-of-language contest. Of course, Zarf's threat to do one in PostScript was a bit more impressive...) But the registry assocation that Explorer uses is set up (at least in Win9x/Me, by default) exactly the same way as for EXE files:

@="\"%1\" %*"

That is, they're directly executable. And there's obviously no magic number in them— they don't even have to have the trailing ^Z (EOF) any more in Windows. So I was wondering how the API can determine that they're batch files, if not by looking at the extension _again_ after Explorer has handed off to CreateProcess.

"In adjectives, with the addition of inflectional endings, a changeable long vowel (Qamets or Tsere) in an open, propretonic syllable will reduce to Vocal Shewa. This type of change occurs when the open, pretonic syllable of the masculine singular adjective becomes propretonic with the addition of inflectional endings."  — Pratico & Van Pelt, BBHG, p68
