为什么我无法从 net logo 的 txt 文件中读取字符串？

Question

我正在尝试从 txt 文件中读取网络徽标中的以下行：

工作1 1 1 15 25 90 3 1111 1100 0010 0110 1011 0 0 0 0 0 0 0 0 0 0 0

然而，我一直收到：预期为常量（第 1 行，字符 5）

在这种情况下我有很多问题。

A) 如何使 netlogo 读取字符串 "Job1"？

B) 考虑到第 10 个数字是二进制数，我怎样才能将其作为字符串而不是数字作为标题？

感谢您的回答。

我不太确定我是否真的得到了你想要达到的目标。您想将 "txt-file" 的所有元素作为字符串读取，但由空格分隔吗？如果是，您可以尝试逐字符读取文件以检查空格之间的字符串长度。然后再次浏览文件并提取这些字符串。这是如何实现它的示例代码。也许还有更优雅的版本，但这个版本非常适合我：

globals
[
  char-list
  char-counter
  string-list
  current-char
]

to read

set char-counter 0
set char-list []
set string-list []
set current-char 0

;; Open the file and go through it, char by char to check where the blank spaces are
file-open "in.txt"

while [file-at-end? = false]
[
  ;; Save current char
  set current-char file-read-characters 1

  ;; Check if the char is a blank space...
  ifelse (current-char != " ")
    ;; If not, increase the length of the current string
    [
      set char-counter char-counter + 1
    ]
    ;; If yes, save the length of the previous string, and reset the char-counter
    [
      set char-list lput char-counter char-list
      set char-counter 0
    ]
]

file-close  

;; Now read the file again and extract only the strings which are not blank spaces
file-open "in.txt"

let i 0
while [i < length char-list]
[
  ;; Read the next number of characters as defined by the previously created char-list
  set string-list lput file-read-characters item i char-list string-list

  ;; Skip 1 space:
  set current-char file-read-characters 1

  ;; Increase i
  set i i + 1
]

file-close

end
