Dear All,
Thank you for emailing me how to translate the YEAR into a LEAP_YEAR
dummy.
 However,  I followed this thru, the FAQs relevant section, and STATA
still is not happy.
Please, see below.

. (mod (YEAR,4) == 0 & mod(YEAR, 100) !=0) | mod(YEAR,400) == 0
unrecognized command:  ( invalid command name
r(199);


Your feedback would be very welcome and much appreciated.
Thank you so much
Panos

This is an FAQ:

http://www.stata.com/support/faqs/data-management/leap-year-indicators/

The Statalist FAQ itself suggests search of the Stata FAQs.
