Thank you for your help, about grammar fixes - good, i will apply it.
About "> miner.bat ECHO @echo off" let me explain - this parts of code creates new .bat file and that .bat file must be with this ECHO OFF option, so no need to remove it.
About REM and :: i will think, thank you, but at this time i will not add it.
Contact me it Telegram t.me/acrefawn if you want to help or talk about it.
Thank you again!
