NAMELIST group [ [ , ] group ]...
group ::= / group-name / name [ , name ]...
Each name must be a variable name. The variable must not be or contain a pointer or allocatable component, if the variable is an array it must have constant bounds, and if it is a character string it must have constant length.
But in Fortran 2003, the variable is permitted to be allocatable or a pointer, to contain an allocatable or pointer component (only if it will be processed by user-defined derived-type input/output), to have non-constant character length, or to have array bounds that are not constant; however, the variable is still not permitted to be an assumed-size array.
Note that if the variable is allocatable or a pointer, it must be allocated or associated at the time of execution of a READ or WRITE statement that uses the namelist group.
Furthermore, if the namelist group is PUBLIC then each variable must also be PUBLIC and must not have any PRIVATE components.

<Semantics> |
|
|
|
The NAMELIST statement declares one or more namelist groups.
Multiple NAMELIST specifications for the same namelist group name are treated as if they were concatenated.
Namelist input/output is done using the NML= specifier in a READ or WRITE statement.
A set of namelist records begins with “&group-name” and ends with a slash (“/”).
This feature is difficult to use reliably, and so is not recommended except for small programs.
