[Fortran] 纯文本查看 复制代码

Program subString
  implicit none
  character(len=20):: str = "hello, world!"
  write(*,*) str(2:2)
  write(*,*) str(2:7)
End program subString

为啥会
Warning：This argument's data type is incompatible with this intrinsic procedure; procedure assumed EXTERNAL.  [INT]
报错：This name does not have a type, and must have an explicit type.   [INT]
报错：Compilation Aborted (code 1)

呢
求解
