INPUT Statement (BASIC)

Reads input from the keyboard or a file.

Syntax

INPUT [;] ["prompt"{; | ,}] variablelist 
or 
INPUT #filenumber%, variablelist

Parameters

prompt: An optional literal string that is displayed before the user enters data. A semicolon after prompt appends a question mark to the prompt string.
variablelist: One or more variables, separated by commas, in which data entered from the keyboard or read from a file is stored. Variable names can consist of up to 40 characters and must begin with a letter. Valid characters are A-Z, 0-9, and period (.).
variable$: Holds a line of characters entered from the keyboard or read from a file.
filenumber%: The number of an open file.

Remarks

INPUT uses a comma as a separator between entries. For keyboard input, a semicolon immediately after INPUT keeps the cursor on the same line after the user presses the ENTER key.

Example

CLS 
OPEN "LIST" FOR OUTPUT AS #1 
DO 
     INPUT " NAME: ", Name$ ’Read entries from the keyboard. 
     INPUT " AGE: ", Age$ 
     WRITE #1, Name$, Age$ 
     INPUT "Add another entry"; R$ 
LOOP WHILE UCASE$(R$) = "Y" 
CLOSE #1 
’Echo the file back. 
OPEN "LIST" FOR INPUT AS #1 
CLS 
PRINT "Entries in file:": PRINT 
DO WHILE NOT EOF(1) 
     LINE INPUT #1, REC$           ’Read entries from the file. 
     PRINT REC$                     ’Print the entries on the screen. 
LOOP 
CLOSE #1 
KILL "LIST"
