Re: Missing Intrinsics for quads

2009-11-18T01:27:17Z

Lots of quad intrinsics are missing and some are there but bugged.
Fortunately the only time I had to use quad precision in a real-world
program (volcanology is certainly real-world!) I needed only *, /, +,
- and real sqrt, all of which were OK.

If z is complex quad and x is real quad, the following were also

Missing Intrinsics for quads

2009-11-17T10:15:01Z

Hi,

I just want to note, that the Fortran intrinsic functions exponent() and
fraction() are missing in g95 for floating point numbers with quad precision.

Maybe there are some others missing too.

Best regards

Private Variables

Here's a silly wee puzzle. The solution is below. Why is there no
error produced from the assignment of 11 to y?

module m
integer, private :: y
end module m

program p
use m
y = 11
end program p

Module m's variable "y" is indeed private; the y being assigned 11, is

The error messages are very useful for debugging, but I need a way to
turn them off when we distribute the software. In the rare(?) case of
a user experiencing a runtime error, it's unacceptable for our program
to write out source code filename (with full path in some cases!) and
line number information. We already have one case of a user getting

Re: Strip filename and line number info

Sure, but in a program one distributes to others, one may want to
conceal such information -- even perhaps that the program is written
in the dreaded FORTRAN language .

Strange, usually, people prefer to get useful information from the
compiler
when a run-time error occurs... (BTW, I can give you some compiler
vendor
whom error messages are very unclear ;-).

I think that the '-s' flag you used remove only the symbol names out
of the
executable file. '(F5.2,A5)' is not a symbol, it is a format string

Strip filename and line number info

2009-11-04T18:22:48Z

Is there a compiler flag that will remove all filename and line number
information from the compiled executable? The example program below
illustrates how at runtime, the filename and line number associated
with the error get written to the screen:

=====fprog.f90=======
PROGRAM fprog
INTEGER :: i, j

Re: Temporary arrays when returning arrays from function calls

This is a little out of this list's scope then. :-) I do know a little C#, but there are plentiful examples out there. I suggest you Google "reading from files in C#". You'll get plenty of info that way.

I solved this problem by linking the coarray.o object file included
with cocon.

Excuse reply to self. The data file that you attached looks somewhat
like a Fortran Namelist, but IMO it's just a dump of variable name /
value.
While it does look like the type of fixed column format input that
Fortran handles easily with its FORMAT statements (or FORMAT
specifiers), this could just as easily have come from "screen scaping"

Re: Temporary arrays when returning arrays from function calls

This is not really a Fortran or G95 question, but here it goes anyway.
The process is similar in any of the Microsoft languages. In one of
the older languages (pre-dot net) you create a form and add a control
(text exit or rich text) to a form. Then pass the input file to the
control. On the output side, you invoke one of the common dialogs for

So I finally got a little more light shed on my assignment. Turns out I misunderstood what he wanted about Fortran. He actually wants us to create a program in C# that reads the .txt file and puts it into a GUI that allows me to change the contents. And when I save it, it must be saved as a .txt file. Don't know if you have any background in C# but I would assume you do. Any advice?

Coarray link errors

2009-11-02T16:06:06Z

I've downloaded the latest g95 source and compiled it. I'm able to
compile 'normal' Fortran code, but I'm getting the following errors
when linking my co-array program:

$ g95 coarray.f90
/tmp/ccyibhwb.o: In function `MAIN_':
coarray.f90:(.text+0x2a): undefined reference to `_g95_this_image'

The file looks a bit like a namelist, which is a Fortran way to read in and out named data. It's kinda neat. But I only say a bit like a namelist; it's missing the end character. (You can google 'Fortran namelist' if you want.)

There is no Fortran source code here though, so I'm at a bit of a loss.

I've got g95 on my machine I don't know about the school computers. I
can attach the text file and send it to you if you want to see it I am
so lost on this one.
