The first of our PR INT statements (line 301 dlsploys a character string or "literal". Notice that
the double quote marks are NOT printed as part of the output. They are necessary to "delimit",
or mark, the beginning or end of the sequence of characters which you wish to print. This
sequence
can
include any character except the double quote character itself.
The items in lhe second and third PR INT statements {lines 40 and 50) should be recognilable
to
all
readers as variables. When a variable name is used within a print list, the value of the variable
is printed. In this case,
we
knew what the values of ZZ and ZS would
be
since they were specified
by lines 10 and 20. Printing an "empty" variable
will result in
a lero
cir
a blanl< depending
on
whether the
variable is
numeric or <:haracter.
Clever readers will have observed that character strings and the values of character variables
arc printed beginning on the left side of the display . This is known as " left justified". By
contrast, numbers and the values of numeric variables are "right justified".
