I have to wonder:  why are these two areas even related?  I would
think that the code that reads SAS data sets (and handles the
firstobs= option) would not have much in common with the code that
writes external files (and handles the filestat option).  And why
would the LRECL of the file make a difference?

Over-optimized code?  Failure to check array boundaries?  One of the
other coding errors that Microsoft Internet Explorer seems so prone to?
