Because columns I, 2, JI. and 32 may not show on your screen,
you may want to use only column-numbers 3 through 30.
Althou~h you may specify a value as largE': ;'li'\ 32767 for char·code.
the computer will convert the value specified to a range of 0
through 255. Character codes 32 through 127 are defined as the
standard ASCII character codes. Character codes l)R throllgh
