Hi! I'm a long-time stata user and new to sas. I'm trying to figure out how to create a new variable based on the sum of the values of another variable.
In stata, I can do this using the "egen" command. For example,
gen CSI1strong = 1 if csi1>5
egen csi1strong=sum(CSI1strong), by(survey)
The first line of code creates a new variable, CSI1strong, that is equal to 1 if csi1>5
The second line of code creates a new variable, csi1strong, that is equal to the sum of CSI1strong for all rows of data, by survey.
How can I reproduce this in SAS?
Thank you in advance for your help!

It would help SAS users more to provide an example of the starting data, the desired result and a description of what goes on if the two examples aren't very straight forward.
SUMing a variable in groups can be done in Proc Means or summary with the groups defined by CLASS variable(s), or in Proc Sql with a Group by.
Then combine the results, how will depend on the data sets.
I don't speak STATA, so that syntax means nothing.
