Tho first of our PRINT statements (line 30) dis1 > lays a character string or "literal". Notice that
the double quote marks are NOT printed as part of tho output. They arc 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 the second and third PRINT statements (lines 40 and 501 should be recognizable
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 lhey were specified
by lines 10 and 20. Printing an "empty" variable will result in a zero or a blank depending on
whether the variable is numeric or character.
Clever readers will have observed that character strings and the values of character variables
are printed beginning on the left side of the d isplay. This is known as "left justifie<I". By
contrast, numbers .;ind the values of numeric variables are "right justified" .
