Origin Ver. Origin 7.5 SR6
Operating System: XP

When I checked some of the labtalk scripts, I found sth like "$Smooth".
What does the $ sign mean? What is it used for?

Hi,

$ sign is one kind of substitutions in LabTalk. You can refer to this page for more information. Please note that this page is for the latest version, Origin 8.1, and some features do not exist in Origin 7.5. If you are interested, you can download a demo and have a try.

I read the wiki and it seems still unclear to me.
This line is from Smooth.ogs in origin files.

%K=$Smooth.Order9;

Does the $ sign in front of Smooth mean something special or substitution?

The notation with leading $ and no following parentheses is indeed special and it means to

$ = Look in the ORIGIN.OMG file
Smooth = In the [Smooth] Section
Order9 = And return the string value of the Order9 keyword

So %K = $Smooth.Order9
assigns
First Second Third Fourth Fifth Sixth Seventh Eighth Ninth
to %K.
