Creating a link in SAS EG
I have been unable to find any documentation on creating links in a SAS EG process flow. Here is an example what I mean by link:
The ones with the dotted lines are created by right clicking and pressing create a link.
But what do they do? my guess is they make one program run after the data it is linked to is created but I am not sure. What are they used for and is there any consequence for using them?
Thank you in advance.
Solution
If you compare those links to traditional CS terms, those links act as a stack. They allow to run operations sequentially.
SAS projects sometimes need to be run as a whole project, so you're giving a hint for SAS what to execute, in what order, etc.
