        Comparison expressions

        Comparison expressions are used to compare values with order in mind (which is greater?).

            A comparison expression is a code fragment which produces a Boolean value, which can then be used as an input for other operations: print, write, method call and so forth.

            A comparison expression has the form a op b where op is one the following comparison operators: <, <=, > and >=.

            Please note that < and >= are mutually exlusive, same for <= and >.

            Also note that Prompto can only compare compatible values (it does not make sense to compare text and number).
        
        Comparing Text values

        Prompto compares Text values lexicographically i.e. using their underlying Unicode representation.
