Priority of conditions

Priority of conditions is as follows:

• Evaluate from the top of Condition list.

• Evaluate contents inside parentheses prior to contents outside.

• Evaluate "and" prior to "or".

How to operate Conditional Branch

Creation of Conditional Branch

Draw a process flow from Condition to the operation that is executed when the condition matches.

Addition of Conditional Branch

Select Add condition from the right-click menu of Start Conditional Branch and add a condition.

= Remarks =

The maximum number of Condition icons that can be added is 98.

Change of the evaluation order of conditions

Select Move up evaluation order or Move down evaluation order from the right-click menu of Condition, and change the evaluation order of multiple conditions. The number encircled on Condition is the evaluation order.

When condition doesn't match

When the condition set in Condition doesn't match, the subsequent operation to which the flow is drawn from Start Conditional Branch will be executed.

If the subsequent operation doesn't exist, the process moves to End Conditional Branch.

In the above example, if the condition doesn't match, the Call Script operation will be executed without executing the Wait operation.

Specification limits

• Even if the condition is added or edited, the update icon (*) isn't displayed on the component icon.

Exception messages

None.

Notes

• If a process flow isn't drawn after Condition, the process will go on to End Conditional Branch.

• The properties windows for Start Conditional Branch and End Conditional Branch can't be opened.

• When you place the operation in a PSP data flow, refer to Align conditional branch components in a PSP data flow.

Operation example

Using the Conditional Branch operation, create a script to execute the Call Script operation only when the number of seconds for the script execution time is an even number.

1. Create a script as follows.

   

2. Create a script variable "var" of integer type.




3. Perform mapping in Mapper as follows:

   • Determine whether the number of seconds for the script execution time is odd or even, and map the value to the script variable "var".

   • If the number of seconds for the script execution time is odd, 1 will be set in "var".

   • If the number of seconds for the script execution time is even, 0 will be set in "var".

   



4. Configure the Conditional Branch operation as follows:

   • If the number of seconds for the script execution time is odd, the condition expression will be false.

   • If the number of seconds for the script execution time is even, the condition expression will be true.

   



5. Execute the script and check the result in the debug information view and the execution log view.

   Debug information & Execution history	The number of seconds for the script execution time	Whether or not the Call Script operation is executed
   	Even	YES
   	Odd	NO
