JSI Tip 8097. Enclosing a set of commands in parenthesis () simplifies some batch files?

Enclosing a set of commands in parenthesis () groups them together.

Example:

@echo First line of new file>"%TEMP%\FileName.tmp"
CD C:\FolderName
@echo Folder is %CD%>>"%TEMP%\FileName.tmp"
dir /b>>"%TEMP%\FileName.tmp"

Then, using parenthesis results in a simpler construct:

(
 @echo First line of new file
 cd C:\FolderName
 @echo Folder is %CD%
 dir /b
) >"%TEMP%\FileName.tmp"
