在动力系机房,用得最多的语言就是FORTRAN了,但FORTRAN有时实在太
烦人,编译太多错误时看都看不清楚,咋办?
在编译时,编译程序会问你:
Microsoft FORTRAN77 V3.13 8/05/83
Object filename [HST.OBJ]:
Source listing [NUL.LST]:
Object listing [NUL.COD]:
一般大家都以回车忽略,其实应该在
Source listing [NUL.LST]:
一行中命名一个LST文件,如A.LST,打开此文件可看到以下内容:
1.FORTRAN 版本信息
2.源程序清单
行号 语句
*****出错信息
3.变量信息
4.总结
这样,就可以清楚看到出错地点,类型,可以方便地查看,然后在源程序中
修改.
附例子如下:
A.LST文件:
