a Fortran question

Hi Gurus,

Sorry if this question is not appropriate for this list.

I have been using DEC Fortran for a long time, performing very
long calculations whose partial results are stored periodically
on disk so that if there is a power failure the work can be resumed
without much loss. Immediately after the partial result is available
the command WRITE can perform this with no problem.

On the other hand I am using also IBM XLFortran and this compiler
does not write on disk so promply - it accumulates the partial results
in a kind of buffer and only after there is a certain amount of data
in that buffer it actually flushes to disk. This is not working to
me since I am loosing much computational effort with frequent
machine uptime interruptions. Does anybody know how to solve this
difficulty? I have tried to open and close the file everytime I
have to write on it, but with no success.

TIA,
