It may be possible if you have a 32 bit version of Windows 7. (IIRC, there are folks on the WordStar list who deliberately got a 32 bit version of Win 7 so they could still run WS7 in it. Win7 is the last version of Windows that has a 32 bit version. Win8 is straight 64 bit.) It is *not* possible in 64 bit versions. Native support for 16 bit applications was dropped. The only way to do it in 64 bit Windows is to run a virtual machine. If you have Windows 7 Pro, you can get Microsoft's VM software and an XP image to run in it, then run the DOS stuff in the XP VM. Others have reported some success with Oracle/Sun's open source VirtualBox VM software, or using VMWare Workstation. Expect to fiddle, regardless. > JAS ______ Dennis ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
