PARADISE Packages for Asynchronous Real-time Ada Drivers for Interconnected Systems Exchange This set of packages has been developped to implement inter-processes, inter tasks and inter-machines communication for ADA programs in the UNIX (BSD and System V) world. These packages give the user full access to files, pipes, sockets (both UNIX and Internet), and pseudo-devices. They also implement useful operation such as FORK or EXEC. All objects are implemented as ADA types, along with all notions that we thought could be useful (Internet adresses, subnet adresses,...) MORE IMPORTANT : blocking IO are no longer blocking the whole UNIX process , but are now just blocking the task requesting data-transfer. These packages are 9000 lines long.The distribution includes a complete manual. It contains a short introduction to PARADISE and to basic mechanisms of communication in UNIX, a description of each important function of PARADISE, and some useful examples demonstrating how PARADISE can be used in a multi-tasking world to communicate with pipes, pseudo-devices, UNIX and INTERNET sockets between tasks, processes and machines. These packages have been developped for the Alsys ADA compiler, and the SUN/OS operating systems, but we think that only minimal modifications are required to compile and run with other compilers or other UNIX/OS. We are very interested in experiments on other machines. If you succeed in porting PARADISE, please tell us. We will try to maintain PARADISE as much as we can, and to provide minimal user support.

We are ready to discuss the possibility of releasing new versions of PARADISE under an other kind of license. PARADISE is available by anonymous ftp on enac5.enac.dgac.fr (143.196.3.5), /pub/paradise.tar.Z.
