FORTRAN 77 Language Reference

Description

An EQUIVALENCE statement stipulates that the storage sequence of the entities whose names appear in the list nlist must have the same first memory location.

An EQUIVALENCE statement can cause association of entities other than specified in the nlist.

An array name, if present, refers to the first element of the array.

If an array element name appears in an EQUIVALENCE statement, the number of subscripts can be less than or equal to the number of dimensions specified in the array declarator for the array name.
