Omitting arguments in commands

[pinkman]

If you need the last argument (background color), because colors and width are integers, you need to provide the intermediate arguments (ie width).
But I don’t see why it should be a problem, because whatever the width you provide (equals or less than 320), TEXTOUT_P will print the text as needed, and will return the next position if you need to print something else.
If you give an insuffisant width value the text will be truncated, that’s why the easiest method is to set width to 320, and the clean method is to set width to (320-x).

Other functions with optional arguments behave the same: the compiler matches the arguments according to the types. There is no syntax (like “,,”) to bypass an argument.
