Carl Mascott ported mawk to V7 and in the process rooted out some subtle (and not so subtle) bugs. Ian Searle ported mawk to System V and put up with my insane attempts to get fpe exception trapping off. An anonymous reviewer for comp.sources.reviewed did the MSC and Mac ports and wrote .bat files for the tests. Another or maybe the same reviewer did the Dynix port. Ports to new systems: Layne Lommen ApolloSR10.3 Ed Ferguson MIPS M2000 C2.20 OS4.52 Jwahar R. Bammi Atari ST Berry Kercheval SGI IRIX 4.0.1 Andy Mason Next 2.1 Mike Carlton Next 2.1 Elliot Jaffe AIX 3.1 The DOS version is a lot better thanks to suggestions and testing from Ed Ferguson, Jack Fitts, Nadav Horesh, Michael Golan and Conny Ohstrom. Arnold Robbins kept me current on POSIX standards for AWK, and explained some of the "dark corners".
