Question: for Question 35 of the National Professional and Technical Personnel Computer Application Ability Exam, how do you do this:
Under Windows 98 “MS-DOS mode”, create a file from the keyboard. The file content is: “I'm a teacher.”, the filename is LX.TXT, and save it to A drive.

First enter MS-DOS mode, then type the following command:

ECHO I'm a teacher. > A:\LX.TXT

OK!

I've learned a lot, although I still didn't understand it! What does ECHO mean?

A:\>COPY CON LX.TXT press Enter
I'm a teacher. press Enter
Press CTRL＋Z then press Enter
