.EXAMPLE.....: 30 Find the date 1 month, 3 months, 1 year from today
.CATEGORY....: examples
.DISCUSSION..:
This example uses Fdate's month-arithmetic function: /Fm.

The /N parm specifies the number of months that we want to add to the date specified on the /A parm. Note that we can specify a negative number on the /N parm, which will return a date which is the number of months BEFORE the date on the /A parm.

In the last example, we find the date one year after February 29, 2004, which is a leap year. Note that Fdate does NOT return February 29, 2005, which is a non-existent date.
