The ONLY clause is part of the USE statement; the syntax of a USE statement containing an ONLY clause is as follows.
USE [ [ , nature ] :: ] name , ONLY: only-list
nature ::= INTRINSIC | NON_INTRINSIC
only-list ::= only-item [ , only-item ]...
only-item ::= name | rename
| rename | ::= | local-name => remote-name |
| | | OPERATOR(local-operator) => OPERATOR(remote-operator) |
Fortran 2003 allows renaming user-defined operators, e.g. “.FRED.=>.NURKE.”, but intrinsic operators such as “.NEQV.” cannot be renamed.

The USE statement accesses public entities in a module.
If all USE statements for a particular module in a scoping unit have the ONLY clause,
only those entities listed in the ONLY lists are accessed.
An only-item that is a rename provides access using a different identifier; the entity named remote-name or remote-operator in the module is available as local-name or local-operator in the USEing scope.
If any USE statement for a module is lacking the ONLY clause, all public entities in the module
will be accessed, but any renaming specified in the ONLY clauses will still be effective.
