Argument Correspondence

The formal arguments of an ENTRY statement need not be the same in order, number, type, and name as those for FUNCTION, SUBROUTINE, and other ENTRY statements in the same subprogram. Each reference to a function, subroutine, or entry must use an actual argument list that agrees in order, number, type, and name with the dummy argument list in the corresponding FUNCTION, SUBROUTINE, or ENTRY statement.

Alternate return arguments in ENTRY statements can be specified by placing asterisks in the dummy argument list. Ampersands are valid alternates. @ ENTRY statements that specify alternate return arguments can be used only in subroutine subprograms, not functions.
