without affecting the execution of the program. However. any extra
blank spaces you put in that are not required will be deleted when
the program line is displayed by the EDIT, NUM, or LIST
command. There are some places where blank spaCPB must not
appear, specifically:
(1) within a line number
(2) within a resnved word
