IMPORTANT
In the above program, and in later chapters and listings in this manual, BASIC
keywords will appear in upper case (CAPITAL) letters. This is how keywords
appear when a program is LIS T ed by the computer. In general it is preferable
that you type instructions or programs using lower case (small) letters, since it will
help you spot typing mistakes when Ll STing the program - (because the
mis-typed BASIC keyword will NOT be converted to upper case).
For the remainder of this Foundation course, we will list programs in both upper
and lower case, so that you get accustomed to this aspect of operation.
A variable's name, such as x or a
$,
will NOT be converted to upper case when the
program is LIS T ed although the computer will recognise the name regardless of
whether it appears in upper or lower case in the program.
Attention
From this point in the manual, you will not be instructed to press the [RETURN]
key after each line. Therefore it is assumed that you will do it automatically.
