The Erase in Display command erases all or part of the display.
This command can be used to erase the area preceding the cursor, the area following the cursor,
or the entire screen. Each erased character is replaced by a blank (the ASCII Space character, 20
Hex) with character attributes "off." The cursor does not move when this command is executed.
If the entire screen is erased, all line types are reset to normal. If a portion of the screen is erased,
all lines except the line occupied by the cursor are reset to normal. In the line occupied by the
cursor, the line type remains unchanged.
NOTE
When the NOCHANGE Attribute Mode is set, erased characters are replaced with blanks, but the
character attributes within the erased area remain unaffected. This makes it easier to erase within a field of
attributes.
