Note: Try this test, and then go to TestYourself answers for Rules containing calculations and equations to correct yourself.
  1. What are the two possible meanings of the equals operator =? In which sections of the Rulesheet is each of these meanings applicable?
  2. 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         
  3. Is the following assignments expression valid? Why or why not? Entity1.integer1 = Entity1.decimal1
  4. 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')         
  5. 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               
  6. The part of Corticon Studio that checks for syntactical problems is called the __________.
  7. 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:

  8. What does Filters row 1 test?
  9. 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?
  10. 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.)
  11. 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
