Change to this:

size = filesize / 1024 / 1024;

Filesize contains the number of bytes. Dividing by 1024 gives you KB, dividing again gives you MB.

One more divsion would give you GB.

You could even use a multiplicator in the format and assign the format directly to filesize.

Some things helping us to help you:

use {i} or running-man icon to post formatted code, this increases readability
explain the expected result

The SAS environment i have access to prints the following error message:

40         
41         data data;
                ____
                57
ERROR 57-185: DATA is not allowed in the DATA statement when option DATASTMTCHK=ALLKEYWORDS.  Check for a missing semicolon in the 
              DATA statement, or use DATASTMTCHK=NONE.

After renaming the dataset the numbers seem to be to high. Maybe using the standard format sizekmgw.d is what you need.
