Large file problems on AIX

[Mark Morss]

When I compile with g95 on AIX 5.0, read statements that refer to a
file more than 2 GB in size return an error code 200. Also when I
write lines to a file, my code fails once the file grows to 2 GB (I
have forgotten the returned error code and I don't have the time to
create an example).

Can anyone suggest how I can get past this problem? There are no
obvious compiler or Fortran options that I can find to deal with it.

P.S. According to the g95 manual, error code 200 signifies "conficting
statement options," however it is very simple to eliminate this error
by cutting the file size and re-running the same executable. So file
size, not conficting statement options, is the problem.
