❏ Namelist-directed I/O
Namelist-directed I/O—previously available as an extension to FORTRAN 77—is a
standard feature of Fortran 90. This feature enables you to perform repeated I/O
operations on a named group of variables. See “Namelist-directed I/O” on page 213 for
more information.
Intrinsics
Fortran 90 provides a large number of new intrinsic procedures for manipulating arrays.
Many of them are elemental, taking either scalar or array arguments. In the latter case, the
result is as if the procedure were applied separately to each element of the array.
Other additions include transformational functions that operate on arrays as a whole, and
inquiry functions that return information about the properties of the arguments rather than
values computed from them.
Table 3-1 on page 81 lists the array-inquiry intrinsic functions. For descriptions of all intrinsic
procedures, see Chapter 11, “Intrinsic procedures,” on page 501.
