OpenVMS lives forever ;) Me likeee ;) hm, i dont know OpenVMS - but googled around a bit for 'VMS asynchronous' and it gave me this: http://en.wikipedia.org/wiki/Asynchronous_system_trap is AST what you mean? From a quick read AST seems to be a signal mechanism a bit like Unix signals, extended to kernel-space as well - while syslets are a different 'safe execution engine' kind of thing centered around the execution of system calls.
