Answer 1

可能是错误

文件名，目录名或卷标语法不正确

是因为文件系统禁止文件名中的:等字符。代码中的文件名表达式：word "output" date-and-time产生类似

的内容

output11:22:04.548 PM 14-feb-2015

根据user manual，格式是固定的，因此子字符串可以提供帮助：

let dt date-and-time  
let fname ( word "output" substring dt 0 2 substring dt 3 5 substring dt 7 26) 
movie-start fname

命名电影输出文件时出现奇怪的错误
