array can also be input with the MAT INPUT statement).
See "FOR Clause in Input List" for more information.
Examples
The following examples show several ways to use the INPUT statement.
INPUT
INPUT A,B$,C(*)
INPUT A,B$,C(*):
INPUT:
INPUT: A,B$,C(*)
INPUT: A,B$,C(*):
INPUT A$ A,B$,C(*)
INPUT PROMPT D$; X,Y, PROMPT D1$+D2$, Z
INPUT "Input 2 numbers",X,Y,PROMPT D1$+"A";Z,"Input name",N$:
INPUT: (FOR I=1 TO 10, W(I), WW(I,I))
INPUT "Input A and elements of V"; A, (FOR J=1 TO 5, V[J]):
An INPUT statement that begins with a colon assigns the values in the
input buffer before prompting you for input or reading it from a file.
An INPUT statement that ends in a colon stores unassigned input values in
an input buffer.
An INPUT statement that does not begin or end with a colon empties the
input buffer before prompting for input.
FOR Clause in Input List
An input list can contain a FOR clause. The FOR clause is similar to the
FOR NEXT construct.
Syntax
(FOR num_var = num_expr1 TO num_expr2 [STEP num_expr3 ], input_item
[, input_item ]...)
Parameters
num_var Assigned the sequence of values: num_expr1 ,
num_expr1 + num_expr3 , num_expr1 +(2* num_expr3 ), etc. The
INPUT statement reads one input value for each value of
num_var that is less than num_expr2 (if num_expr3 is
positive) or greater than num_expr2 (if num_expr3 is
negative).
num_expr1 First value assigned to num_var .
num_expr2 Value that num_var is compared to before the INPUT
statement reads a value. If num_expr3 is positive and
num_var > num_expr2 , loop execution is terminated. If
num_expr3 is negative and num_var < num_expr2 , the loop
execution is terminated.
num_expr3 Amount that num_var increases by at the end of the loop.
The default = 1.
input_item Same as input_item in INPUT statement syntax.
Examples
10 INPUT "Input 4 numbers: ", (FOR I=1 TO 4, A(I)), "Input X: ", X
If you input the underlined values during execution:
Input 4 numbers:
