TestYourself questions for Rules containing calculations and equations

What are the two possible meanings of the equals operator =? In which sections of the Rulesheet is each of these meanings applicable?

What is the result of each of the following equations?

1. 10 + 20 / 5 – 4        
2. 2 * 4 + 5        
3. 10 / 2 * 6 – 8        
4. 2 ** 3 * (1 + 2)        
5. -5 * 2 + 5 * 2        

Is the following assignments expression valid? Why or why not? Entity1.integer1 = Entity1.decimal1

What is the data type of each of the following expressions based on the scope shown in the following figure?

• e1.dateTime1.year        
• e1.string1.toUpper        
• e2 -> forAll (integer1 = 10)        
• e2.decimal1 -> avg        
• e1.boolean1        
• e1.decimal1 > e1.decimal2        
• e2.string2.contains('abc')        

Write "valid" or "invalid" for each of the following assignments

• e1.decimal1 = e2.integer1        
• e2.decimal2 = e2.string2        
• e1.integer1 = e2.dateTime1.day              
• e2.integer1 = e2 -> size        
• e1.boolean2 = e2 -> exists (string1 = 'abc')              
• e2.boolean2 = e1.string1.toBoolean              
• e1.boolean2 = e2 -> isEmpty              

The part of Corticon Studio that checks for syntactical problems is called the __________.

True or False. If an expression typed in Corticon Studio does not turn red, then the expression is guaranteed to work as expected.

Referring to the following illustration, answer questions 8 through 10:

What does Filters row 1 test?

What does Conditions row "a" test? Is there a simpler way to accomplish this same thing using a different operator available in the Corticon Rule Language?

Write a Rule Statement for rule column 1. (Assume that the only action required for this rule is to post a Warning message as shown.)

True or False. The following sections of the Rulesheet accept equations and calculations:

• Scope        
• Rule Statements        
• Condition rows        
• Action rows        
• Column 0        
• Condition cells        
• Action cells        
• Filters
