PATTERN Matching - Need To Escape % Character?

I have two files in a folder:

test.jpg
test-25%.jpg

Select PATTERN % selects both files
Select PATTERN '% selects the 2nd file

% is not listed as a special character in Pattern Matching Syntax in the Help File. Why does it have to be escaped and are there any other unlisted characters that need to be escaped?

You can use environment variables with the select command, via the usual %var% format.

For example:
[ul][li]Create a file called Windows_NT.txt and this command will select it:

Select PATTERN %OS%
[/li]
[li]Create a file called the same thing as your computer and this will select it:

Select PATTERN %COMPUTERNAME%[/li][/ul]

Ah OK. Thanks Leo - that explains it. I've submitted a support request for the Help File to be updated.
