Covers all seven possibilities

Another reason that I included the three different formulations was to illustrate the use of all seven of the relational and logical operators in the following list.

• Less than:  <
• Greater than:  >
• Less than or equal to:  <=
• Greater than or equal to:  >=
• Logical AND:  &&
• Logical inclusive OR:  ||
• Logical NEGATION:  !

These seven operators plus the following equality operators constitute the entire set of relational and logical operators supported by Alice:

• Equal to:  ==
• Not equal to:  !=
