	It is possible. However, whichever version you install second will overwrite the symbolic links in /usr/bin, /usr/lib, /usr/include and so forth. That means you have to extra care- ful when running applications. That is you should have your path setup to point through the appropriate bin directories. For instance set path = (/usr/kits/DMA32A/bin $path) should guarantee that you are running V3.2A. this would have to be done in your shell login script (.profile, .login, .cshrc or equivalent). similarly when building applications you need to be careful when compiling against the include files and linking against the libraries. lastly, you need to worry about running applications. applications need to be linked against the run- ning version. if you have a single application that you want to run against the two different versions you would need two sepa- rately linked images of that application and make sure you run the correct one. In short it is more trouble than it is worth. _sjz.
