97. Printing listings (1)
    ~~~~~~~~~~~~~~~~~~~~~
Here is a handy little routine, for using a red key to LIST your programs
without fuss. It is particularly useful if you want to LIST a number of
programs one after another. The routine selects LISTO7 to format the listing
nicely, cancels paged mode, switches the printer on, LISTs the program,
switches the printer off, re-engages paged mode, and then cancels the LISTO.
Please note that the spaces are for clarity only, and should be omitted, even
though it looks mighty odd!
