NAMELIST

[brunocalado]

[cpp]REAL (KIND=8), ALLOCATABLE	:: A(:)
REAL (KIND=8), ALLOCATABLE	:: B(:)

NAMELIST /vars/ A, B
[/cpp]

I'm trying to read a file with A and B, but when I read a get the folowing message:

forrtl: severe (18): too many values for NAMELIST variable, unit 11, file /test,


How can I use NAMELIST to read allocatable arrays?

With no example of your source code or data file, it is nearly pointless to attempt an answer. From the fragment you have shown, I would say don't try non-standard extensions until you have it working with a standard-compliant example.

My guess is that you did not allocate the arrays first. If you are expecting a NAMELIST read to do the allocation, you are mistaken.

C:Projects>type t.f90
REAL(8), ALLOCATABLE, DIMENSION(:) :: A,B

NAMELIST /vars/ A,B

ALLOCATE (A(2), B(3))

A = 1.0
B = 2.0

READ (*,vars)

WRITE (*, vars)

END
C:Projects> ifort /nologo t.f90
C:Projects t.exe
&vars A = 4,B = 5,6 /
&VARS
A = 4.00000000000000 , 1.00000000000000 ,
B = 5.00000000000000 , 6.00000000000000 , 2.00000000000000

You will need the latest 11.1 for this, as some earlier versions did not allow ALLOCATABLE arrays in NAMELIST at all.
