How to create a new column in a SAS Data Studio Code Transform step?

[TheBugSlayer]

Hello. Don't ask me how I landed on SAS, but it's now on my plate so I am learning...

In my data plan, I am trying need to add a column to an existing dataset. The way I found to do it is by adding a column in a code transform. However, I am struggling to create a variable then assign that variable to the new column. I have looked at a few articles and I feel I am pretty close. As a matter of fact one of the iterations worked but I did not save it before. The error I am getting with this code is

The action was not successful
ERROR: Expecting an arithmetic operator.
ERROR: Syntax error, statement will be ignored.
ERROR: Statement is not valid or it is used out of proper order.
ERROR: Expecting an arithmetic operator. (occurred 16 times)
ERROR: Syntax error, statement will be ignored. (occurred 16 times)
ERROR: Statement is not valid or it is used out of proper order. (occurred 16 times)


Here is my code:

/* BEGIN data step with the output table data */
data {{_dp_outputTable}} (caslib={{_dp_outputCaslib}} );
/* Set the input set */
set {{_dp_inputTable}} (caslib={{_dp_inputCaslib}} );
length _renamed $50;
if LabName = 'THIS LAB' THEN _renamed = 'THAT LAB' ELSE _renamed = LabName;
"Laboratory_Renamed" = _renamed;
/* END data step run */
run;

What am I doing wrong?

Thank you!
