well it isn't bordland... it is borland, and I have already given ample instruction on how to set up your compiler in your other post on this subject.
do a 'find' on your computer under your start bar for autoexec.bat. Modify your path statement as I stated in your other thread on this subject.
don't use notepad... get familiar with using a command prompt (console). Your computer comes with edit.exe. It is a good text editor for writing code (automatic tab delimination etc). Run a console... type edit myfile.cpp from the prompt. Write your code... click file/save (or alt and the arrow keys).
