@Stu Sztukowski and @Tom.

The solution turned out to be stripping the datasets of their formats, then importing them into SAS Studio. Two ways to remove the formats are:

1. Exporting the data to a .csv file with PROC EXPORT:

proc export data=data.climate23_nf
  outfile='H:\CHIS\Data\climate23_nf.csv'
  dbms=csv
  replace;
run;

2. Removing the formats manually from within a data step with this code:

data data.climate23_nf;
    set data.climate23;
        format _numeric_   ;
        format _character_  ;
run;

I did both steps as part of preprocessing in SAS EGP and saved the files to a local directory. I then imported the files in SAS Studio using Build Models --> New Project --> browse for data --> Import --> Local Files.

I appreciate suggestions from both of you; they were very helpful.

Thanks,
