Adding Parameters to a command
A parameter is a letter typed after a command that tells the command to carry out an extra task.

This part Tells MS-DOS to
COPY Make a copy …
A: MEMO.TXT .. of the file MEMO.TXT on drive A: …
C:\ … and put it on drive C:
/v and at the same time verify that
the file is recorded correctly on C:
Most parameters are optional, however you will discover, over time, ones that you use frequently.
