Probably safer to first convert the string to a -date- and then start any
translation/extraction action...

***
clear
input country:mylabel /* 
 */ str10 date, auto 
Argentina   "199001"
Argentina   "199001"
Argentina   "199001"
Argentina   "199002"
Argentina   "199003"
Argentina   "199004"
Argentina   "199004"
Argentina   "199004"
Argentina   "199004"
Argentina   "199101"
Argentina   "199101"
Argentina   "200803"
Argentina   "200804"
Argentina   "200804"
Brazil      "199001"
Brazil      "199002"
Brazil      "199002"
Brazil      "199003"
Brazil      "199003"
Brazil      "199003"
Brazil      "199003"
end
compress

gen double date2=/*
*/date(date,"YM")

Dear statalists,

Something wrong happened when changing the string variable into date
variable.

 clear
input country:mylabel /* 
 */ str10 date, auto 
Argentina   "199001"
Argentina   "199001"
Argentina   "199001"
Argentina   "199002"
Argentina   "199003"
Argentina   "199004"
Argentina   "199004"
Argentina   "199004"
Argentina   "199004"
Argentina   "199101"
Argentina   "199101"
Argentina   "200803"
Argentina   "200804"
Argentina   "200804"
Brazil      "199001"
Brazil      "199002"
Brazil      "199002"
Brazil      "199003"
Brazil      "199003"
Brazil      "199003"
Brazil      "199003"
end
g date2=monthly(date,"YM")

The result showed "21 missing values generated"

Anything wrong? How to correct it ?

Thank you for any help!

Best regards,
Rose.
