7.2.1 Sequential READ Statements

Sequential READ statements transfer input data to internal storage from external records that were sequentially accessed. They can be formatted, list-directed, namelist, or unformatted, taking one of the following forms:

Formatted

READ (extu,fmt [,iostat] [,err] [,end]) [iolist]
READ f [,iolist]

List-Directed

READ (extu, *[,iostat] [,err] [,end]) [iolist]
READ *[,iolist]

READ (extu,nml [,iostat] [,err] [,end])
READ n 

Unformatted

READ (extu [,iostat] [,err] [,end]) [iolist]

extu

Is an external unit specifier.

fmt

Is a format specifier.

iostat

Is an I/O status specifier.

err, end

Are transfer-of-control specifiers.

iolist

Is the I/O-list specifier.

f

Is the nonkeyword form of a format specifier.

*

Is a list-directed format specifier. This parameter can also be specified as FMT=*.

nml

Is a namelist specifier.

n

Is the nonkeyword form of a namelist specifier.

The control-list parameters are extu, fmt, iostat, err, end, f, * (or FMT=*), nml, and n. The I/O list parameter is iolist.
