命名电影输出文件时出现奇怪的错误

Question

我好像找不到错误原因。

工作代码：

print word "output" date-and-time
movie-start "output"

无效代码：

movie-start word "output" date-and-time

错误：

error (IllegalStateException)
 while observer running MOVIE-START
  called by procedure GO
  called by Button 'go'

Answer 1

可能是错误

The filename, directory name, or volume label syntax is incorrect

是因为文件系统禁止在文件名中使用:这样的字符。代码中的文件名表达式：word "output" date-and-time 生成类似

的内容

output11:22:04.548 PM 14-feb-2015

根据user manual，格式是固定的，所以子串可以帮忙：

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