The syntax for a function call is simple; use the function name followed by a list of expressions, separated by commas, of data type corresponding to the function prototype.
Today()
GetEasterFor(nYear)
The result of a function call can either be assigned to a variable
nToday = Today()
nDateEaster = GetEasterFor(nYear)
or it can be used as parameter of another function call, as below, in nested function calls.
nWeekDay = WeekdayOf(Today())
nMayFirst = FirstDateOfMonth(YearOf(Today()),5)
Some functions are called void, because they do not return any result. These are usually function that act on the databases. They are called simply, without assigning their result.
Reset_FindNextHolidayOnDate()
