Execution of a logical assignment statement causes evaluation of the logical expression e and assignment of the resulting value to v. If e is a logical expression (rather than an integer between -128 and 127, or a single character constant), then e must have a value of either true or ...

Integer m,n Real a(m,n) a=2 End Subroutine sub 只传递地址,维度由定义确定,各维度上下限由其他虚参确定,参数多。 假定大小(Assumed-size) Subroutine sub(a) Real a(*) a(1:6)=1 End Subroutine sub 只传递地址,虚参只能是1维,下线为1,不传递上限,容易越界。
