NAMELIST output uses a special form of WRITE statement, which makes a report that shows the group name. For each variable of the group, it shows the name and current value in memory. It formats each value according to the type of each variable, and writes the report so that NAMELIST input can read it.
WRITE ( extu, namelist-specifier [, iostat] [, err])
and group-name has been previously defined in a NAMELIST statement.
The NAMELIST WRITE statement writes values of all variables in the group, in the same order as in the NAMELIST statement.

Note that if you do omit the keyword NML then the unit parameter must be first, namelist-specifier must be second, and there must not be a format specifier.
