I have a SAS data set which just has the variable names for each variable:

Separately, I have two CSV files - one that contains the variable label (file is in 'long format'):

and one that contains the response option labels (also in 'long format'):

I would like to apply the variable labels and response option labels to my SAS data set. I imagine uploading my CSV files to SAS, to make data sets, but then after that, I am not sure how to proceed. It seems that Proc datasets may be an option, but I have not been able to find an example that I could figure out to apply to my scenario. Any help - as always - is much appreciated.
Best, Camilla
