I have a line of Fortran code, which includes some text. I'm changing the text, which makes the code line too long for Fortran, so I split it over two lines using 'a'. Was: IF (MYVAR .EQ. 1) THEN WRITE(iott,'(A) (A)') 'ABC=', SOMEVAR Changed to: IF (MYVAR .EQ. 1) THEN WRITE(iott,'(A) (A)') 'ABC DEF GHI JK a ' // 'L=', S...
Is there an analog of the "-fdefault-real-8" gfortran (the GNU Fortran 95 compiler) option in g77 (the GNU Fortran 77 compiler)? This option sets the default real type to an 8-byte wide type. I currently have code where single-precision arithmetic is limiting my accuracy, and so I need double-precision. (It's not just intermediate val...
Hi, has anyone successfully compiled a pro*fortran program on windows that connects to Oracle 10g? I can only seem to find information that suggests that pre-compilation of embedded sql is possible against Oracle 8i and earlier. If you have done this please can you post any links you have for compilers, oracle downloads/articles etc a...
I need to convert a code from Fortran77 to Compaq Visual Fortran. Is it possible? If "yes": is it also possible to save the results in a form that can be imported in EXCEL 2003? ...
I want to save results in a text file. How can I do that? Write command? ...
I have a file that is compressed and I want to decompress it. Do you know if there is a command or do I need to follow another path? ...
I have a compressed file. Let's ignore the tar command because I'm not sure it is compressed with that. All I know is that it is compressed in fortran77 and that is what I should use to decompress it. How can I do it? Is decompression a one way road or do I need a certain header file that will lead (direct) the decompression? It's not a...
I've a question about Fortran 77 and I've not been able to find a solution. I'm trying to store an array of strings defined as the following: character matname(255)*255 Wich is an array of 255 strings of length 255. Later I read the list of names from a file and I set the content of the array like this: matname(matcount) = mname ...
I'm trying to write binary data files from fortran, but I find the regular file interfaces very limiting, I wonder if Fortran has POSIX compilant functions. I found this standard: IEEE 1003.9-1992, but I don't know it if is fully supported by most common compilers (or if I have to activate any flags). I can't find any practical informat...
I am a beginner trying to do some engineering experiments using fortran 77. I am using Force 2.0 compiler and editor. I have the following queries: How can I generate a random number between a specified range, e.g. if I need to generate a single random number between 3.0 and 10.0, how can I do that? How can I use the data from a text f...
In a .f file there is code that does this: real Bob, avar ... avar = Bob( 8.3 ) ... Bob appears to be a function but it is declared at the beginning of the file as a real. Then there is a .d file that has a reference to Bob. Also I know avar holds a value that appears is interpolated, The problem is the interpolation is not always r...
Hi, I am porting the application with old fortran compiler and old visual studio(VC5) to new fortran compiler 11 and visual studio 2005. Application contains both 'C' and fortran code. I am compiling the fortran code and creating library called server_lib.lib(library is createing with some warnings) and linking to the 'C' code. while l...
I am looking for an rpm or simple install instructions for getting f2c to work on my redhat linux os. I am new to linux and it is difficult finding something like this on google. (The goal is to use f2c to convert a simple fortran77 file to c, then compile) Does anybody have any suggestions? ...
Can somebody please point out what I'm doing wrong here? FORTRAN 77 dll code *$pragma aux DON "DON" export parm(value*8,value*8) SUBROUTINE DON(DAA,DBB,DCC) REAL*8, DAA,DBB,DCC DBB=DAA+1 DCC=DBB+1 RETURN END C# code using System; using System.Collections.Generic; using System.Linq; using S...
I have a project that is half in C and half in Fortran 77. [No, not Fortran 90 or 03, Fortran 77.] The code would be much cleaner if I could pass pointers generated on the C side back to Fortran, which would then pass them back as necessary for handling in other C functions. As it is, the C code is filled with global variables that shoul...
I'm attempting to work in Fotran 77, and I've found the need for a tree based data structure. Aside from implementing a tree with an array, is there any way to build a tree with pointer nodes to other nodes, as per a standard implementation in most languages? The documentation for this beast is scarce, and there doesn't appear to be any...
What is the motivation for defining PI as PI=4.D0*DATAN(1.D0) within a Fortran 77 code? I understand how it works, but, what is the reasoning? ...
When using the following to compute PI in fortran77, will the compiler evaluate this value or will it be evaluated at run time? PI=4.D0*DATAN(1.D0) ...
I have some old fortran 77 I'm trying to port to gcc on Windows. I'm using gfortran 4.4. The statement uses READ(FOO, '(F)' , ERR=BAR) BAZ and gcc is complaining about F. From what I've seen it looks like F needs a size associated with it. There are also FORMAT statements which use a similar construct. What is the proper way to port t...
Background: I am working on a project written in a mix of C and Fortran 77 and now need to link the LAPACK/BLAS libraries to the project (all in a Linux environment). The LAPACK in question is version 3.2.1 (including BLAS) from netlib.org. The libraries were compiled using the top level Makefile (make lapacklib and make blaslib). Probl...
