尝试编译时出现如下所示的大量错误：
user@DESKTOP-57BGLNH:~$ pwd
/home/user
user@DESKTOP-57BGLNH:~$ ls

user@DESKTOP-57BGLNH:~$ cobc -x testdoc.cob

*对于上下文，
我在 VSC 中，我打开远程窗口并使用以下代码创建一个新文件：
identification division.
program-id. Assignment1.
environment division.
configuration section.
data division.
working-storage section.
01 out pic x(11) value "Hello World".
procedure division.
display out.
goback.
end program Assignment1.
File> Save.
打开新终端，并使用 pwd 和 ls 确保我在正确的目录中，如您所见，“/home/user”是文件“testdoc.cob”所在的目录，按照 ls 命令。然后我使用“cobc -x testdoc.cob”编译，然后我得到了这些系列的错误。为什么是这样？我哪里错了？
我试过在具有不同扩展名的新文件夹中重复该过程，结果都是一样的。
