NSIS scripting file error while extracting a zip file

When I am using the following NSIS script:

ZipDLL::extractall "C:\Users\sid008\Desktop\NSISTutorials.zip" "F:\nist" "<ALL>"
then I am getting the below error:

!define: "MUI_INSERT_NSISCONF"=""

Changing directory to: "C:\Users\sid008\Desktop"

Processing script file: "C:\Users\sid008\Desktop\Ext1.nsi" (ACP)Error: Can't add entry, no section or function is open!
Error in script "C:\Users\sid008\Desktop\Ext1.nsi" on line 1 -- aborting creation process

As the error points out, to use ZipDLL::extractall, you must call it from within a Section or Function.
