```
支持的操作符：
- `==` 等于
- `!=` 不等于
- `>` 大于
- `<` 小于
- `>=` 大于等于
- `<=` 小于等于
### if语句
```
if 条件
then
条件为真时执行的代码
else
条件为假时执行的代码
end
if 条件 then 真代码 else 假代码
```
### 示例
```
if hello == world
then
conshow match
else
conshow no match
end
var(text) num1 = 10

## 循环
### loop语句
```
loop 次数
循环体代码
end
loop << 变量名
```
执行变量中的代码，无限循环。
### 示例
```
loop 5
conshow count: i
var(text) count = i
conshow count: count
end
var(text) code = conshow hello
loop << code
```
## 字符串操作
### 读取字符串
### 读取字符串并执行
```
rstr 变量名
```
执行变量中存储的代码（支持\n换行）。
### 示例
```
var() myString = Hello, World!
rstr myString
conshow myString
var(text) mycode = conshow hello\nconshow world
rstr mycode

```
### 乘法
### 创建目录
```
var(text) result = num1
var(text) num1 = 10
var(text) num2 = 20
rstr result + num1 * num2
conshow result
diskfile create dir 路径
```
### 除法
### 写入文件
```
var(text) result = num1
var(text) num1 = 10
var(text) num2 = 20
rstr result + num1 / num2
conshow result

### 支持的命令
- `cat` - 显示文件内容
- `echo` - 写入文件
- `ls` - 列出目录
- `pwd` - 显示当前目录
- `mkdir` - 创建目录
- `rm` - 删除文件
- `rmdir` - 删除目录
## 注意事项
1. **大小写敏感**：命令和变量名区分大小写
2. **空格处理**：参数之间用空格分隔
3. **错误处理**：不支持的命令会显示错误消息
3. **变量存储**：所有变量都作为文本存储，运算时会自动转换
4. **注释支持**：使用#号添加注释
5. **变量作用域**：变量在整个脚本中有效
6. **条件嵌套**：支持多层条件判断
7. **循环嵌套**：支持多层循环
6. **无限循环**：loop命令会无限循环，需要使用end或其他方式退出
7. **文件系统**：使用diskfile前需要先执行diskfile reg注册VFS
