Message-ID: <185@riv04.UUCP> Date: Wed, 20-Jun-84 11:47:19 EDT Article-I.D.: riv04.185 Posted: Wed Jun 20 11:47:19 1984 Date-Received: Fri, 22-Jun-84 08:05:52 EDT Organization: RIVM, Bilthoven, Holland Lines: 24 F77: A number of the applications programs we buy are in Fortran 77. Unfortunately, we have some problems with f77 under Unix : - Arrays of char* can be viewed as 'internal files'. Each array element can be read as a record, and the end should deliver 'end-of-file'. Some combinations don't work (at least under our V7 and 4.1BSD). - The mathematical library refuses to generate floating exceptions. In cases like 'sqrt(-1)' they always return 0. Is there a reason ? - There is little input checking when reading floating point numbers. It is possible to read a real '1. o 2', it returns 1.2 ... - Ever heard of 'assigned format statements' ? Some programs depend heavily on them. We can't get them going. - And some more (lesser) problems ... Who has had similar difficulties, and somehow solved them ? Who is the author of / supports Unix f77, and especially : how can we reach him ? Fortran programs may not be your favorite (nor ours), but they keep showing up, and we don't have the manpower to reinvent everything ... Any help / suggestions would be greatly appreciated, Jean-Claude Wippler Please reply by mail, I might overlook news : ..!mcvax!riv04!jc
