Preference File Syntax
Every statement in a script begins with an asterisk, *. Lines without asterisks are treated as comments.
In the statement *Font("Helvetica", 1, 1, 12), Font is the keyword and the arguments ("Helvetica", 0, 1, 12) specify that the font is Helvetica bold italic size 12. If a statement is left out of a script, the program uses the default setting specified in the preferences file. For settings not specified in the preferences file, the program uses built-in defaults. If a statement is repeated within a block, the last occurrence of the statement is used unless specified in the statement description, in which case, multiple occurrences are used.
