Certainly! Here are some common formulae and functions related to batch scripting:

1. For Loop(对于循环):

   • Formula(公式): for /L %%variable in (start,step,end) do command
   • Example: for /L %%i in (1,1,10) do echo %%i

2. IF Statement(IF语句):

   • Formula: if condition (command) else (command)
   • Example: if exist file.txt (echo File exists) else (echo File does not exist)

3. Variable Assignment(变量赋值):

   • Formula: set variable=value
   • Example: set myVar=Hello

4. Command Line Arguments(命令行参数):

   • Formula: %1, %2, ...
   • Example: echo The first argument is %1

5. GOTO Statement(GOTO声明):

   • Formula: goto label
   • Example: goto start

6. Functions (using call)(函数,用于调用):

   • Formula: call :functionName arg1 arg2 ...

   • Example:Call it: call :myFunction

     :myFunction
     echo This is a function
     exit /b
     

7. String Manipulation(字符串操作):

   • Formula: %variable:~start,length%
   • Example: set myString=HelloWorld then %myString:~0,5% gives Hello

These are some fundamental elements of batch scripting. Let's practice by using these in a sentence:
