This is the technique that is used when running QSIM under ACL on Windows 95. QSIM displays the results of a simulation by writing the information for a requested display to a file and then invoking an X-windows program that reads the file and displays the results. One of the issues that must be addressed when installing QSIM on a new Lisp is that the installer must find out how to make a foreign function call from within Lisp and must add the appropriate call to the X-windows program. This symbol is a read-time conditional. Currently, we have already included the command for most of the publicly available Lisp implementations.
More information is contained in the installation manual.
If you do install QSIM on a new version of LISP, please contact us with information about your experiences. Install Allegro Common Lisp on a PC running Windows 95 2. For the QSIM installation, please refer to the installation instructions . There are two measures you can use to determine whether the installation is successful. The problem may just be in the mechanism used to load the example files from the menu since this can be a little flaky.
