INPUT Abbr. none
INPUT string; input list
Accepts your input from the keyboard during program execution. The pro
gram waits for you to type the input and press the RETURN key before it
continues. You can add a question to the INPUT command to help the user
understand the type of input expected.
Parameters: "prompt question"; variable(s)
1. The prompt question, which is optional, must be in quotes. If you omit the
prompt, do not put the semicolon before the variable.
Do not type a question mark at the end of the question. Whether or not you
include a prompt question, INPUT displays a question mark to indicate that
keyboard input is expected. If you add the prompt question, the automatic
question mark is displayed at the end of the question.
Note: If you do not want a question mark to be displayed for keyboard input,
OPEN the keyboard (device number 0) as a file. Then, PRINT your prompt
(ending with a semicolon) and use INPUT# to read the keyboard.
2. The data values you input from the keyboard are assigned to the INPUT
variable.. Use text-string variables for text input. You can use more than one
variable in an INPUT command. If you do, separate the variables with commas;
the semicolon is used only to separate the prompt question (if there is one) from
the variables. If you use more than one variable, you must enter a value for each
(separated by commas) before the program can continue. Otherwise, a double
question mark will prompt for the rest of the input.
Example: 10 INPUT "WHAT'S THE DESTINATION"; D$
SO PRINT "PACKAGE TO ";D$
RUN
WHAT'S THE DESTINATION? LONDON
PACKAGE TO LONDON
INPUT# Abbr. iN
INPUT# file number, input list
Retrieves a data value from an OPEN file or device and assigns it to variables.
INPUT# works like INPUT, but instead of getting data input from the keyboard,
INPUT# gets data from a file or device. The file or device must have been opened
using the same logical file number. See also GET#.
