8. Responding to INPUT with too many or too few items,
or with the wrong type of value
(numeric instead of
string, etc.), or with a carriage return causes the
message R?Redo from startR to be printed. No
assignment of input values is made until an
acceptable response is given.
9. There ·are two new field formatting characters for
use with PRINT USING. An ampersand is used for
variable length string fields, and an underscore
signifies a literal character in a format string.
10. If the expression supplied with t~e WIDTH statement
is
2SS, BASIC uses an RinfiniteR line width, that
is, it does not insert carriage returns. WIDTH
LPRINT may be used to set the line width at the
line printer. See Section 2.66.
11. The at-sign and underscore are no longer used as
editing characters.
12. Variable names are significant up to 40 characters
and can contain embedded reserved words. However,
reserved words must now be delimited by spaces. To
maintain compatibility with earlier versions of
BASIC, spaces will be automatically inserted
between adjoining reserved words and variable
names. WARNING: This insertion of spaces may
cause the end of a line to be truncated if the line
length is close to 2SS characters.
13. BASIC programs may be saved in a protected binary
format. See SAVE, Section 2.60.
