Internal READ statements transfer input data to internal storage
from an internal file.
Namelist formatting is not permitted with an internal READ
statement.
The internal READ statement can be formatted or list-directed, taking one of the following forms:
READ (intu,fmt [,iostat] [,err] [,end]) [iolist]
READ (intu, *[,iostat] [,err] [,end]) [iolist]
The control-list parameters are intu, fmt, iostat, err, end, and * (or FMT=*). The I/O list parameter is iolist.
