How can we get to know whether a flat file is used or VSAM file is used inside the program?

If the file in the program used has a select statement like the below
For KSDS
Code:
SELECT <file>  ASSIGN    TO  <filename>
       ORGANIZATION  IS INDEXED         
       ACCESS MODE   IS RANDOM         
       RECORD KEY    IS <key field>   
       FILE STATUS   IS < file status flag>. 


For RRDS
Code:
SELECT <file>  ASSIGN <filename>               
                   ORGANIZATION IS RELATIVE           
                   ACCESS MODE  IS RANDOM             
                   RELATIVE KEY IS RECORD-NUMBER     
                   FILE STATUS  IS <file status flag>.


For Sequential
Code:
SELECT <file>  ASSIGN <filename>           
                  FILE STATUS <file status flag>.
