set by the last TextColour command and the alignment set by the last TextAlign command.
expression_list is a list of expressions containing variables, constants, string variables or quoted
strings. Each expresion is separated by a comma. The format$ contains information on how to
format each item in the expression list and must not exceed 255 characters in length. For each
item in the expression_list there must be corresponding format item in format$.
Details on what may appear in format are given below.
Formatting numbers
To format numbers use the # character to represent each digit and the period to represent the
decimal point. The number of digits before and after the decimal point can be varied by adding
# characters. An example for format$ is “##.###”. Negative number are prefixed with a minus
sign. The number may also be represented in scientific format using a format such as
“#.###^^^^”,The ^ characters represent the position of the exponent termEsxx where E denotes
the exponent , s is the sign (+ or -) and xx is the power of 10 to be used.
Note The scientific format must have 4^ characters and must have only one # charater before
the decimal point. For example, we show the result of displaying hte number 123.4567 with
variaous formats.
Format Result
###.### 123.456
###.## 123.46
#### 1234
#.####^^^^ 1.2345ED2
String Characters
To format a string variable, string functions or quoted strings use the $ character to represent
each character of the string. The character string is left justified in the format string if the format
string is longer than required. For long strings you do not need to use a large number of $
characters. If the format is “$n”, where n is a number between 1 and 256, then it acts as if n $
characters were used. The format"$*" acts as if the same number of $ were used in the format
as appear in the string.
For example, below is the result of displaying the string “PCS Software” with various formats.
Format Result
$$$$$$$$$$$$$ PCS Software
$$$$$$ PCS Sof
$8 PCS Softw
$* PCS Software
Other characters
All other characters in the format string are printed without alteration.
