Question

我正在尝试从命令行向Fortran可执行文件传递参数。在C中实现此目的的示例程序是（取自here）：

#include <stdio.h>

int main (int argc, char *argv[])
{
  int count;

  printf ("This program was called with \"%s\".\n",argv[0]);

  if (argc > 1)
    {
      for (count = 1; count < argc; count++)
    {
      printf("argv[%d] = %s\n", count, argv[count]);
    }
    }
  else
    {
      printf("The command had no other arguments.\n");
    }

  return 0;
}

该程序的输出是：

This program was called with "./fubar".
argv[1] = a
argv[2] = b
argv[3] = c

我现在的问题是，我如何在Fortran中编写此程序（以及此功能）？我用google搜索过，似乎只有Fortran 2003具有将参数传递给可执行文件的功能（这是正确的）吗？

Answer 1

为了将来参考，正如@High Performance Mark在上面指出的那样，在Fortran 2003中很容易做到这一点。下面的示例代码取自here并显示如何：

      PROGRAM test_get_command_argument
        INTEGER :: i
        CHARACTER(len=32) :: arg

        i = 0
        DO
          CALL get_command_argument(i, arg)
          IF (LEN_TRIM(arg) == 0) EXIT

          WRITE (*,*) TRIM(arg)
          i = i+1
        END DO
      END PROGRAM

从命令行将参数传递给可执行文件
