Endianess and Fortran

Endianess and Fortran

[Hassan Aurag]

 This is new to me. What are the things to watch when dealing with
porting Fortran programs from old big-endian machines to Linux on Intel?

 I heard EQUIVALENCE statements are a problem. What are the other things
to watch for?

 Any help or pointer to Fortran related issues is welcome.


 Thanks

Well, it's hard to enumerate all the possible problems with switching to
a system with a different endianness than your original one.

There's one problem we *always* hear about:  It is not possible to read
unformatted files produced on your old system on your new system.

So transfer any needed data by writing it out as formatted data.

Hope this helps,
