A BASIC program is a collection of "lines" with each line being composed of
numerals (integers from 1 to 9999 can be used) called line numbers and state-
ments (commands such as INPUT or formulas such as
Y=2*X t 2+91 *
X
+

The program will also be executed in successive order starting from
the smallest line number.
We will start now by inputting the above program.
