F2003's get_command_argument() intrinsic
All, I was reading through the description of get_command_argument(). It has the form get_command_argument(number [, value, length, status]) where number is the argument number that one wants information. value, length, and status are option, and from the description none of these are required. Thus. pro... 20 Jun 2010 13:27

looking for some advice on program organization
Hello everyone, I'm learning a little bit about organization in fortran, and was wondering, if I could trouble you for a bit of answers on some questions - well, ... advice more, actually. The answers I'll find in a manual, but good experience is hard to come by. The structure of most of my programs (f77 mostl... 24 Jun 2010 11:49

Functions with side effects in I/O list
The following code definitely is ill-advised (a function changing its arguments is not a good idea). Is it also illegal? module foo implicit none contains integer function f(i) integer, intent(inout) :: i i = i + 1 f = i end function f end module foo program main use foo implicit... 19 Jun 2010 15:39

Random number in Fortran 90/95

preprocessing issue with Visual Studio
To demonstrate this issue, I created three files. The first 'dim.h' is a head file with a variable definition in it: #define dim 2 The second file 'typ_boundary.f90' contains a module definition: #include "dim.h" #if (dim==2) MODULE TypBoundary_2D #elif (dim==3) MODULE TypBoundary_3D #endif INTEGE... 19 Jun 2010 01:35

Commercial Fortran Compilers
I am in the market for a single copy of a commercial* Fortran compiler to use under Windows. I'm seeking advice on the options. Because I am a one-man, part-time consulting shop, price is important. Lahey Express is cheap, but apparently it's not being updated any more. Intel and Absoft both seem good and curre... 24 Jun 2010 18:35

Why was SPREAD left out of initialization expressions?
I know RESHAPE is allowed in Fortran-95+ initialization expressions, but why is its "cousin" SPREAD not allowed? Al Greynolds www.ruda-cardinal.com ... 17 Jun 2010 15:37
