In particular, when conversion to _Bool is required any mumeric value that isn't zero gets converted to 1 (didn't carefully check what happens to imag... 22 Jan 2008 16:16

Compatibility of MOD files
How come the .mod files are not compatible between different compilers? E.g., a .mod file produced by Intel Fortran Compiler (ifort) cannot be used by g95, etc. It's very cumbersome when installing some libraries with Fortran bindings - even if the library has been compiled and all the required .mod files are alrea... 24 Jan 2008 14:34

Is there a way to construct a generic "list" by Fortran 95?
In my finite element program, I want the Load, Element ..... are defined by list type. If there is a generic list type can be defined by Fortran 95, it will be convenience. Then, it can be difine: Type(list) :: Load Type(list) :: Element ..... call add(Load, i) call add(Element, i) .... A generic list ty... 23 Jan 2008 19:43

gfortran -std=f95 overzealous?
I use INDEX and LEN_TRIM in some initialization expressions and gfortran complains that their use here is an extension to the Fortran-95 standard. None of my other compilers complain (with f95 compliance ON) . The standard seems to say any intrinsic involving only integer and/or character types is allowed. Who's... 25 Jan 2008 04:19

FITS Library Package upgrade
Hello, I have updated my FITS (Flexible Image Transport System) Library Package. Besides fixing a few bugs related to writing header keywords under certain conditions, the major improvement is that one can now write output to the input file even when the dimensions of an image extension have changed. One c... 20 Jan 2008 22:04

code to find average values
Hi, Could you please give me some hints to find the average of the following value of 1.1, 2.2, 3.3 and 4.4 only, seperated with 3 others values, using Do Loop in Fortran 90: 1.1 2.0 3.0 4.0 2.2 2.2 2.0 3.0 4.0 3.3 3.3 2.0 3.0 4.0 4.4 4.4 2.0 3.0 So that I can get (1.1+2.2+2.2+3.3+3.3+4.4+... 20 Jan 2008 18:09
