To determine if a number is Odd or Even you could use Odd() function found in several Pascal dialect (for example: in Lazarus, Turbo Pascal and Delphi you'll fund the Odd() function in the System unit).
An equally easy trick is by using the mod operator.
The mod operator (you can find it in most other languages as well: %, mod, and rem or remainder are pretty common) returns the remainder of a division. For example 7 mod 2 would result in 1, since 7/2 = 3 and a remainder of
1 ... (3*2=6)
if MyNumber mod 2 = 0 then
... // This is an EVEN number
else
... // This is an ODD number
