[AccessD] OT:Batch File Syntax

Hi Arthur
The %%X stuff looks way cool
The If Exist and goto syntax options have worked beautifully
The Batch file is now much smarter - I have incorporated this newly learned
logic to many areas of the file - a lot more powerful and intuitive now
Many many thanks - I am grateful

Time for an article on the %%X stuff me thinks

Darren

Oops. That was supposed to be %%x not %x%. And to hell with the suspense,
here's an example:

for %%x in (system, command, shellnew, system32) do dir "%windir%\%%x" /W

This won't run straight from the command line. Save it as a file called
fordemo.cmd and then run it.
