Jen,

Just to add to your trivia collection, a year is a leap year if ...

1. It is evenly divisible by 400

2. It is not evenly divisible by 100 and it is evenly divisible by 4

So, for example;

* IsLeap
LPARAMETERS pnYear
LOCAL llLeap
llLeap = (pnYear%400 = 0)
IF NOT llLeap
   llLeap = (pnYear%100<>0) AND (pnYear%4=0)
ENDIF
RETURN llLeap
