BASIC
Keywords
INPUT
Statement
INPUT[;] ['~prompt";]uariabl[,u~rzabl,
...I
Accepts data from the keyboard and inputs it into 1 or more
variables. When BASIC encounters this statement,
it
stops exe-
cution and displays a question mark. This means that the pro-
gram is waiting for you to type something.
Prompt
is a string constant that BASIC displays before display-
ing the question mark prompt.
Prompt
must be enclosed in quo-
tation marks, and follow the keyword INPUT. If, instead of a
semicolon, you type a comma after
prompt,
BASIC suppresses the
question mark when printing the prompt.
Variable
may be 1 or more string or numeric variables t o receive
the input. If you specify more than 1 variable, separate them by
commas.
If INPUT is immediately followed by a semicolon
(;I,
BASIC does
not echo the
[ENTER]
key when you press it as part of a response.
When typing multiple pieces of data on 1 line, separate the data
items with a comma. The number of data items you supply must
be the same as the number of variables you specify.
Responding to INPUT with too many items or with the wrong
type of value (including numeric type) causes BASIC to print the
message "?Redo from start." No values are assigned until you
provide a n acceptable response.
