In a Profile, these four values (normal rows and columns; alternate rows and columns) can be inherited from the Host definition or a linked, parent profile. The Track Marks (
) will indicate if the value is from the Host, a parent Profile or unique to this profile.
Note that you generally do not need to change these values as the Terminal Type sets it for you.
See the Host Screen Rows (default), Screen Columns (default), Screen Rows (alternate) and Screen Columns (alternate) Topics for more details.
