AppleScript和加载代码库

纯粹作为一个实验，我试图用AppleScript做一些相当复杂的事情，主要是作为一个学术练习，而不是任何东西，但我遇到了麻烦。下面是正在发生的事情

首先，我有一个名为“ascr\u code\u library.scpt”的代码库，其中只包含一个方法：

on return_string_position(this_item, this_str, delim)
    set old_delims to AppleScript's text item delimiters
    set AppleScript's text item delimiters to delim
    set this_list to text items of this_str
    set found_pos to 0
    repeat with i from 1 to the count of this_list
            if item i of this_list is equal to this_item then set found_pos to i
    end repeat
    set AppleScript's text item delimiters to old_delims
    return found_pos
end return_string_position

然后，我有了这个脚本，“test-2.scpt”。它的功能非常简单，并且非常简单：

set scr_lib to load script (choose file with prompt "Please pick a library")

tell scr_lib
    return_string_position("Who", "Who am I?", " ")
end tell

但当我运行脚本并选择文件时，得到的是以下错误：

*“«数据SCPT4D617259332E3000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000*

那么我错在哪里呢？据我所知，它正在正确加载脚本。但在这样一个简单的脚本中，我还能出什么差错呢？我试着在方法调用前加上“my”，但也没用。有什么想法吗？

如中所述，我更喜欢这个脚本，因为它避免了分隔符并返回每个实例

on return_string_position(this_item, this_str)
    set theWords to every word of this_str
    set matchedWords to {}
    repeat with i from 1 to count of theWords
        set aWord to item i of theWords
        if item i of theWords = this_item then set end of matchedWords to i
    end repeat
    return matchedWords
end return_string_position

return_string_position("very", "The coffee was very very very very very ... very hot.")

您可以这样调用脚本：

run script file ((path to desktop as text) & "test 1.scpt") with parameters {"very", "The coffee was very very very very very ... very hot."}

你的代码对我来说很好，没有错误。一定还有什么事你没有告诉我们。。。因为你展示的代码是有效的。
