I have an old version of f95 (2.52) which works OK on Windows 2000. Up till now the executable programs work OK on Windows XP and Vista machines. Howevere I encountered a fatal error when using the executable cod on a Winows Vista 64 bit machine. All of the features seemed to work except that at one point I got a fatal error:

"Floating Point Coprocessor fault"

I have not folowed through the diagnostics yet (the actual fault was flagged in code that I had not written).

My questions are these:

If I but a new version of f95 compiler can I use it on both 32 and 64 bit machines? (not at the same time of course because that would invalidate the license?)

If I use the the compiler on a 32 bit machine will a binary work on a 64 bit machine?

If I do the compilations on a 64 bit machinewill the binary executable work on a 32 bit machine?

If the answer to these last two questions is NO this is not a problem, since I can always distribute ytwo versions of the executables

Final question. Can I generate complete binaries? That is can I generate
distributable code that is entirely self contained, and does not require ant DLL's to be included in adistribution?

I wonder if you mean ftn95 rather than f95.

If you are using ftn95 then you can download the current free personal edition and try that. There is a good chance that it will work OK.

The error report could relate to a function call with the wrong return type, i.e, the function return type has not been declared.

Peter,

When the 64bit OS is XP then the answers are as follows (I would not expect 64bit Vista to be different) :-

If I but a new version of f95 compiler can I use it on both 32 and 64 bit machines?

- Yes

If I use the the compiler on a 32 bit machine will a binary work on a 64 bit machine?

- Yes

If I do the compilations on a 64 bit machinewill the binary executable work on a 32 bit machine?

- Yes

regards,
John
