How does one go about selecting observations from two datasets based on 1:1
matching of 3 variables?  I have tried -findit- match and found information
on merging datasets and matching during analysis but nothing that appeared
to address my needs exactly.

I have two datasets, heart.dta (100 obs) and cvd.dta (200 obs) and have been
asked to create a new dataset by matching (1:1) observations on age, race,
and menopausal status (pmp).

 age is continuous
 race is binary
 pmp is binary
 
Furthermore, the matching for age should be based on a difference of less
than five years.

Thank you
