Upgrsde from Visula Fortran 6.6C to 11.1 & Windows7

[davidgraham]

I have been using Visual Fortran 6.6C. There is very little development going on but there is occasionaly the need for bug fixes and some additional features. There has been no need to upgrade in the past.

I now have a Windows7 computer and I will need to support the software in the future.

Is there any advice on upgrading:
1. Would Visual Fortran 6.6C run on Windows7 - this would be the simplest option.
2. Do I neded to upgrade to Visual Fortran 11.1
3. Is there an automatic upgrade. How much will I need to change my code.

I have just gone through the process of upgrading Visual Basic code from VB6 to VB2008.

Thanks,
David

Please read Migrating from CVF for helpful information. You should not have to change your code. If you have VS2005, 2008 or 2010, you can use the CVF project conversion "wizard" to convert your projects, otherwise you will have to create a new project and add the source files to it.

Please note that the current version is Intel Visual Fortran Composer XE 2011, aka version 12.0. Feel free to ask here if you have questions after reading the above article.

If your Windows 7 installations support VPC/XPM (several optional components which depend on your platform supporting virtualization), you can install CVF inside. This remains limited to 32-bit mode, with no support. It's by no means the simplest option nor a popular one.
I don't see any reason to prefer ifort 11.1 over a more recent version, as you apparently aren't using IMSL.
