An expression may consist of only a constant — also called a
literal value — or can include constants, operators, property
references and functions.
Use these guidelines to enter constants. The value you type may depend
on the Type of the property. Include all quote characters as shown.
(Don't use Microsoft Word Smart Quote characters; use only the ASCII
double quote character "
to identify constants.)

Example

TrueFalse
|
Enter "true" or "false" or "T"
or "F."
In most cases, such properties appear as a checkbox or radio
buttons. Avoid the null value "" for a
TrueFalse property; in many but not all
settings, it is the same as "false".

"true"

Text

Enter two double quotes for the null string.
For normal text, enter printable characters (other than
double quotes) between two double quotes. You can include single
quotes within the double quotes.
Use the two character sequence \" to include a double
quote.
Use Java character escapes to include tab characters (\t),
backspace (\b), newline (\n), form feed (\f), carriage return
(\r), backslash (\\), and \zzz for the Latin-1 character
identified by the octal value zzz, between 000 and 377.

Date
|
When a date constant appears alone in an expression, include
double quotes to prevent the value from being interpreted as an
integer. B-18347 and CLINB
Enter two or four digits for the year, two digits for the
month, two digits for the day.
If the year contains two digits, the system uses an algorithm
to determine a "reasonable" century based on the
current date. During 2006, the system prefers dates between 1997
and 2097.
The valid expression
12/10/2006
is an expression involving two divisions and three integers,
whereas
"12/10/2006"
is an American-style date.
The empty string and "" are equivalent to
"19700101" or January 1, 1970. In settings where this
is not desirable, processing can test for and block this date
value. SR-7115

- Two digits for the day
- The single
T (or t or period . or comma

GMT for the zone.
The year, month, and day are required.
Separate the date and time portions of the value with either
T , t , a single space, or a punctuation
mark such as a period or a comma.
If you include milliseconds, separate the seconds from the
milliseconds with either a period (. ) or a comma
(, ). Use the GMT time zone only.
The time portion is optional. If you omit the time portion,
follow the guidelines above for Date constants, by enclosing the
value within parentheses.
If the year contains only one or two digits, the
system uses an algorithm to determine a "reasonable"
century based on the current date. During 2007, the system
prefers dates between 1998 and 2098.
