On publication Pascal

Having recently read several new Pascal textbooks, I was struck by the multitude of ways in which programs are represented in print. Some of these are more pleasing to the eye than others, and with a typesetting machine, anything is possible. However, several books are being produced these days from typewritten copy and there seems to be no accepted second-best to the italics-and-bold favoured by most publishers. It would also be desirable if the style used by books could correspond more closely to that which is handwritten or computer-produced. This note summarizes the possibilities and makes a call for stability, if not outright standardization.
