Labels define their height by multiplying the LINES value by the height of the label's font (including any interline spacing). For example, a LINES value of "1" indicates one line of text. Labels define their width by multiplying the SIZE value by the width of the "0" (zero) character of the label's font.
When the program executes on a non-graphical system, the values specified in the CLINES and CSIZE phrases, if present, replace the values specified by the LINES and SIZE phrases.
The default value of LINES is "1". The default value of SIZE is computed by measuring the length of the label's title using the label's font and dividing by the width of the "0" character. Thus, the default width of a label exactly occupies the space its text takes up on the screen.
To get a multi-line label, set the LINES value to the number of lines wanted and the SIZE value to the desired width. SIZE specifies the width that each line of the label will occupy.
