Hi,

I've enabled "delayed environment variable expansion". How can I use an
exclamaton mark in filenames in my batch files?

Regards,

Piotr

Trial and error shows that this works:

@echo off
echo. !b!.txt
setlocal enabledelayedexpansion
for /L %%a in (1,1,9) do (
set b=%%a
echo a=%%a, b=!b!
dir /b "^!b^!.txt"
)
