Since there are six # symbols and one decimal point specified, a total
of
seven
columns will be used for the printing
of
the number. The number will be printed
"right justified" in this seven column field, meaning that there may be some blanks in
the left most columns, but not in the right-most.
Instead.
of
using a constant string, such as
"####.##",
it is permissible
to
use a
string variable for the format specifier. For example, the program can be changed as
follows
as
A$
=
"####,##"
S0 PRINTUSING A$;
eM
This will give the same output
as
before. Again, the value printed for the commission
will be rounded to the nearest
cent. Note that the format specifier, whether it is a
string or a string variable, is always followed by a semicolon.
For some more examples, suppose CM
= 1416.3812 (actual value as computed) and
this is printed out with line 50 above. The following table gives the output for various
format specifiers
format specifler
A$ =
"####.##"
A$ =
"####.#"
A$ =
"#####.###"
A$
=
"####.#####"
output
1416.38
1416.4
1416.381
1416.38120
Experiment
#3
Dollar Signs
There are other possibilities for format specifiers. Change line 45 in the program so
that it is:
as
A$
=
"$######,##"
Now run the program and input a variety
of
values for the sales. In each case there
will be a dollar sign
($) printed to the left
of
the field (9 column). In many cases there
will be some blanks between the
$ and the left most digit
of
the number.
Now change line 45 so that it
is:
as
A$
=
"$$######,##"
Run the program with a sales amount
of
1111.
As
you can see, the $
is
now printed
just to the left
of
the number $166.65. The use
of
two dollar signs to the left
of
the
numeric field specifier instructs the computer to print a dollar sign immediately to the
left
of
the leading digit.
Experiment
#4
Checks
Many times, payroll checks are printed with asterisks padding the leftmost columns
of
the field.
Change line
45
in the previous program to:
as
A$
=
"**$######,##"
