Other people have already written about having to write (A<B) AND (C>D)
to get what in normal mathematical notation would written A<B AND C>D.
In pascal you can also apply the relation operators to the boolean
values. Thus the "implies" operator can be written as <= in Pascal.
Assume A and B are integer variables and C and D are boolean variables.
Then (A<B) AND C <= D is valid Pascal, but try figuring out what it means.
