An overview of the characteristics of the intrinsic data types, the mechanism for defining structural types, and the syntactic rules for the clarification of scalar data objects, arrays, array sections and structures of various types is presented. The three levels of dynamic sizing of arrays are also considered, namely, dynamic storage allocation for arrays whose size is known at run time, dynamic availability of the size of deferred-shape arrays and availability of automatic local arrays. Moreover, the pointer functionality as available in Fortran 90 is discussed and its syntactic constraints are pointed out.
