I suggest you follow the steps below:
Learning batch processing:
1. Familiarize yourself with the built-in commands. It's best to practice them one by one.
2. Try to write an entertaining batch script by yourself.
For example:
@ECHO OFF
REM command
ECHO **********
pause
if errorlevel 0 goto exist
:exist
call batch.bat
……
3. When you are more or less familiar with the built-in commands, try to write a useful batch script by yourself.
For example:
@ECHO OFF
ECHO Start running virus...
start myvirus.exe
......
4. Familiarize yourself with other third-party tools and commands, and apply them in your own batch scripts.
Configuration:
1. Start practicing with built-in tools such as HIMEM.SYS EMM386.EXE.
2. Pay attention to the DEVICE, DEVICEHIGH commands.
3. When you are proficient with the built-in tools, you can look for alternatives.
