o save me -memory

‘o save me’ memory cries
heed and keep data light
byte is all that’s necessary
if variable v is 0 or unity

choose the optimal data type
to save memory and keep data light
but if you’re not sure what is best
trust Stata and use -compress-

-compress- reduces memory
by demoting the type of v
if v is string with maximum length three
-compress- stores v as str3 not str20
if v is 1 to 32740
-compress- stores v as int not floatie
