Format with implied do loop
In a write statement that contains an implied do loop such as: print *, (k, k = 1, numk) is it possible to add a format that has a variable: write (*, '(x, numk(I3))') R Fitch ... 2 Feb 2010 14:46

Another class of "DO10I=" bug
[You may recall the apocryphal story that a period-for-comma typo combined with implicit types caused the destruction of a NASA rocket launch -- assignment statement "DO 10 I=1.10" where loop statement "DO 10 I=1,10" was intended. Some sources indicate the story is fiction; however, it still is dramatic.] As ... 4 Feb 2010 11:06

should not g95 be downward compatible
I've recently been forced to change from g77 to g95, and g95 flags declaration statements which contain initialization values, such as INTEGER x/5/ to be errors. Is there a compile-time option I can use to cause this to NOT be an error? --Myron ... 27 Jan 2010 17:09

namelist input of multidimensional array?
I'm curious if anyone has some example code of how to input a 2-D (or, in principle, n-D) array via a namelist file in Fortran 95 (I'm using a reasonably current "gfortran" compiler)? I can load a 1-D array (a vector) easily enough and have tried a number of permutations on that syntax, but I haven't been successf... 21 Jan 2010 10:01

ODE solver
I'm looking for an ODE solver that is particularly suited to very large systems, i.e. thousands to tens of thousands of equations. I'm currently using the Fortran90 version (by John Burkardt) of the code from Sandia (Watts and Shampine) implementing "Low-order Classical Runge-Kutta Formulas with Stepsize Contr... 20 Jan 2010 01:50

Maths constants
What is the best way to define mathematical constants for use in Fortran? For example I could define module Constants real(8), parameter :: E = 2.718281828459045d0 ! e real(8), parameter :: PI = 3.141592653589793d0 ! pi end module Constants but there are other possibilities. Is there a recommended standa... 2 Feb 2010 14:46
