In general, older OS/2 programs run very well on later incarnations of the operating system. The Convenience packs (v. 4.5) incorporate major changes to the kernel, but I would hesitate to blame that without further evidence. Ada on OS/2 is not dead, though. Gnat on Intel PC started out as an OS/2 program, before Windows NT became the major PC operating system. Although ACT no longer provides ready-made binaries for the OS/2 version of the compiler, newer versions (up to the current 3.15p) are available thanks to the efforts of Dave Parsons. I use gnat 3.14p on OS/2 (v. 4.0) very regularly on fairly large programs and have never had a problem with it. I have so far not moved up to 3.15p (sorry, Dave), but I hope to do that one of these days. Gnat is of course Ada 95, whereas Alsys was Ada 83. That in itself should present no great problems. There are just a few minor issues which can be easily fixed. But if any Alsys-specific libraries are involved, that would of course be a different matter. Feel free to contact me privately, if I can be of any further assistance. Kees de Lezenne Coulander -- C.M. de Lezenne Coulander Aircraft Development and Systems Engineering B.V.
