在fortran 95中初始化向量

Question

I am using a external program that is run by a script. The script require a direction vector to be specified - this is how programs manual describes it:

real(kind=dp) :: direction(3)

So when running the program script I specify:

direction = (/0.5,0.5,0.5/)

The program yields an error saying it can't read the direction vector - could you tell if I am doing something wrong or this is actually a bug. Thank you.

Answer 1

This

direction = (/0.5,0.5,0.5/)

is syntactically correct for a Fortran statement to set the values of the direction array. But it is not syntactically correct in a namelist file. In such a file either

direction = 3*0.5

or

direction = 0.5,0.5,0.5

is correct.
