(IFGE(arg1,arg2,arg3,arg4))
If arg1 is greater than or equal to arg2, IFGE returns the value of arg3. If arg1 is less than arg2, IFGE returns the value of arg4. The data types of arg1 and arg2 must match and the data types of arg3 and arg4 must match.
In the following example, the value of vifge is 4, because the date 01/10/2013 is greater than the date 10/15/2012.
SET VAR vifge = (IFGE('01/10/2013','10/15/2012',4,5))
