Michael Many thanks. This is much more flexible than my registry hacks. It works a treat as I use LNKs to run different projects in any case. Just goes to show one should always check out a program's command line options before complaining about lack of flexibility. By the way, does anyone know if VS .NET is going to be more flexible in handling project specific settings?? Perhaps even allowing you to define editor color settings for ASM files?? Define a color for virtual spaces?? (The whole VS IDE and editor seems to be several generations behind such tools as Ed for Windows and Codewright in these areas.) Gary
