Fortran

[Demas Ami]

Dear Sir/Madam,

I'm new to linux. I tried to compile my fortran program using G77 and it
works. But when I run
the program, after I type the input file and the designated output file,
the program got aborted.
I already put the input file in the same directory as the program. My
program work in windows
using MS compiler.

I use the following sintax for open file:

open(unit=5, file='inputfile', status='new')
open(unit=6, file='output', status='unknown')

read(5,*)n ...........(something like this)

write(6,*) hf  ........(something like this)

Is it impossible to write program in linux(g77) using the input file
and writing the output into fiel

Thank you for your kind attention and cooperation.

Best regards,

Suwito

Well, as far as you showed us your program, this is all standard fortran
77, so it should work when compiled with g77.

However, there's one problem with it:

You read from a file for which you stated on the open statement that it
doesn't exist yet: "open(...,status='new')

That's only possible if you first write to the file on unit 5, before
reading from it (you also have to rewind before reading).

The snippets you showed are not conclusive in this regard, but if you
only intend to read from unit 5, you cannot open it with "status='new'".

If you do, you'll get the following error from the run time library:

open: 'new' file exists
apparent state: unit 5 named infile

Cheers,

I didn't speak a single word english as I started programming with BASIC on
the C-64 with the age of 8.

I never had a problem with using "if" instead of the german word "wenn" in
my programms, but having a german handbook helped a lot..

(nowdays I don't care much about german documentation, but that is a
different story ;-)

OK, fair enough. For sure, it is the case that efforts at translating
keywords have not caught on in mainstream use at all. Even translating
error messages is not common, and most professional programmers tend
to read english pretty well anyway.

The open question is whether it may be helpful to students learning
a language for the first time. I don't have an opinion on that. I
simply don't know, and there is no point in guessing when in fact I
suspect there are plenty of people who do have experience they can
relate (probably they are not readers of this list, where this
topic is only marginally on topic :-)

my point is, it leeds to nowhere, especially in a open-source community, where
there is a special demand on common agreements. so, i believe, a piece of
software shouldn't contain keywords like 'eger' or variable names like 'aaa'.

if that was the case, then i apologize.

i'd love to see more productive ideas on increasing the heterogenity of
software.
nevertheless, i think now you misunderstood me: i never wanted to reject
anything, since i am in no position to do something like that. rather, i
wanted to discuss the idea of translating programming languages.

If you do not agree with me, you are saying that it is not the case
that this makes sense to many people. I think that is just plainly
wrong, there have been lots of efforts at such translation.

If you are disgreeing with the idea, as seems to be the case, then
you did not read my message clearly. I never gave my own opinion
on the subject! you don't know whether you agree with me on the
issue of translation, because I did not give my opinion, and do
not care to.

My point was that this is a perfectly reasonable thing to
pursue from a technical point of view if someone thinks
it is interesting to do, and I think it is more useful on
this list to be inclusive of all kinds of different
approaches and projects than to reject ideas you don't
like :-)

none of those translated languages have survived, AFAIK.

i do not agree to you: especially initial student introduction should aim
towards developing in a common style. that is, every CS student in the world
should learn the same thing, and (s)he should be able to find tons of
information from the internet. 
i regard programming language keywords rather as symbols than words, that
could be ever translated. but that's just my view ...

> Not all the world speaks english :-)

here i totally agree, and i want to repeat my argument: as much documentation as
possible should translated.

There is a long history of versions of standard languages with
keywords translated into various languages. Translating the
keywords is of course easy enough. What is harder in some cases
is when the structure of a compound statement (such as if else)
does not match the native language.

So in fact to many people, it makes sense, especially say for
initial student introduction, to do these kind of translations.

i believe, that it is possible to implement quite easily, but why would you do
that? although the semantics of fortran wouldn't be affected, many developers
could be confused by different syntax (= language) of the same language.
so, IMHO, the translation of a programming language does not make much sense,
but i believe, documentation translations are highly welcome!
