G77 NAMELIST help

G77 NAMELIST help

[Michael T. Wolff]

Hi!

I have a quick question.  I would like to run programs with 
the fortran NAMELIST statement in them with g77  under Linux 
Red Hat. But, when I try to run the compiled programs on my
Linux computer they die at the first instance of input via 
the NAMELIST statement.  So, I go to the internet to get some
help with the exact syntax of the NAMELIST statement under GNU 
fortran and I always seem to find the following statement:


The NAMELIST statement, and related I/O constructs, are supported 
by the GNU Fortran language in essentially the same way as they are 
by f2c.


Only problem is I can not find any detail on how f2c supports 
the NAMELIST statement anywhere!  Will someone point me to 
a good version of a f2c manual that will give good details on,
for example, what the exact syntax of the NAMELIST statement 
is?

I do not think there's any significant difference between the NAMELIST
formats f2c and g77 support, and NAMELIST as it got standardized in
Fortran 90 - so a book on Fortran 90 should suffice.

Namelist format is as follows:

& group_name
name1=value1
name2=value2
name3=value3/ (/ is the terminating character)

The f2c documentation can be found at http://www.netlib.org/f2c/f2c.ps

It claims that the f2c namelist is the same as fortran 90 namelists, with
some exceptions that are mentioned in the doc.

It has been my experience that g77 namelist files and namelist
specifications have to match pretty exactly, with little tolerance for
error and poor error messages.
