Windows 7 and Compaq 6.6C

[longthong]

I am running 6.6C under Windows XP and am very happy. I am thinking of getting a new DELL computer (faster). Does COMPAQ Fortran 6.6C work in the Windows 7 yard? I have heard bad things about Windows 7 and XP programs. Like you have have a special version to run XP programs. Why can't we live with XP forever?

The reports are that it does not work there - mainly because of its Visual Studio 6 environment that makes assumptions not valid on Windows 7. Please consider moving to Intel Visual Fortran, a current and supported product.

As you're probably aware, Windows 7 has a facility called XPM to run a virtual Windows XP 32-bit, but this has various limitations, performance not even up to par within its limitation to a single thread. This may perform as well as your old computer. I don't know whether you could pry the information out of Dell as to which of their models support this (ours doesn't). A minimum requirement would be that the CPU model shows VT-x support at http://ark.intel.com/
If you're interested, no doubt you can find information on line as to why Microsoft discontinued XP, and on the pros and cons of using an old compiler "forever."

XP Mode no longer requires VT support, but there is a minimum edition of Windows 7 required to use it. See http://www.microsoft.com/windows/virtual-pc/download.aspx

Without hardware virtualization support, one may incur more limitations on features and performance, as this note from Microsoft says.
