Sounds like it's working the way file I/O works.  While local (non static)
variables in the procedure get initialized with each call, the state of the
file cursor will persist from call to call unless you do something like
close the file or explicitly reposition the file cursor.  You might want to
look at the way you're accumulating the totals and see if you can reduce the
amount of I/O.  A single SETLL should have a trivial effect on performance
in an interactive program.
