The script begins by initializing the CAS session and assigning all available CASLIBs. Then, it uses a DATA STEP to copy the 'sashelp.baseball' dataset to a new CAS table named 'baseball_stats' in the 'casuser' CASLIB. Once the data is in CAS, 'PROC MEANS' is executed on 'casuser.baseball_stats' to calculate descriptive statistics. Finally, the script lists the complete history of CAS session actions, which is useful for debugging and auditing.

DATA STEP Data
Explanation :
This DATA STEP creates a new CAS table named 'baseball_stats' in the 'casuser' CASLIB. It copies data from the SASHELP dataset 'sashelp.baseball' into this new table. The execution of this DATA STEP occurs on the CAS server.
