BASIC Version 3.S Commands, Functions, and System Variables 73
Note, however, that while a PRINT command can end in either a trailing
semicolon or a trailing comma, a PRINT USING command can end only in a
trailing semicolon. Also, while PRINT command items can be separated by
either commas or semicolons, only commas are allowed as item separators in a
PRINT USING command. The PRINT USING command allows more control
over output because the format definition determines exactly how the output
looks, so there is no need for semicolons as separators in a PRINT USING
command.

The # before the $
forces the $ to be
printed right next to
the first digit. With
out the leading #,
blanks appear
between the $ and
any unused digits in
the format.
VIDEO EQUIP
MENT is longer than
the 12 letters allowed
by the format, so it is
truncated.
On this run, the
number of digits
entered for the price
is greater than the
number accepted by
the format, so the
field is filled with
* symbols. Words
that are too long are
truncated; numbers
that are too long are
not printed at all.
