4.3.3.3.1 ENTERING A CONDITION STRING
A condition string comprises one or more individual conditions linked together by
the logical operators ! NOT, & AND, | OR and parentheses ( ). Conditions are
chosen from a list. To enter a condition string correctly you must follow these
rules:
There must be an equal number of closed and open parentheses.
All conditions must be separated by either the & or the | operator.
Condition strings cannot end in an operator.
To enter a condition string, first highlight the condition string field. The second
line from the bottom of the screen displays the valid operators and parentheses.
The screen symbols will change depending on the contents of the condition string
to the left of the blinking cursor. To select a symbol, press the corresponding key
number. In the example displayed, the bottom line tells you that you press the “0”
key to select a condition or, the Enter key to finish and validate the string. A
blank condition string is evaluated as false.
While entering the condition string, pressing the “0” key will present a screen
which has a list of condition types at the left side. For the chosen type, the right-
hand side of the screen displays a list of sub-conditions or a number entry field.
Example:
If you move the marker of the left column onto the State condition type, a list of
all the possible states will appear in the right column. See Figure 4-12. To select
one of the states, press the right arrow key to move the marker to the right
column. You then move onto the desired state and press enter. This will return
you to the previous screen and add the selected state to the condition string. You
can return to the left column without selecting a state by pressing the Left-arrow
key.
