Martin,
I am sorry.
You wrote "failed to find the reference Nick cites". I found it, so I told you.
NO dispute. No criticism.
Forgive me if anything wrong.
Best regards,
Rose

I am not disputing this fact! I failed to find the reference in spite of a
comprehensive scan of this very help file. So the criticism was entirely
directed at myself ...

Martin，
what Nick cites is in the help for -dates_and_times-.
Best regards,
Rose.

I thought about this solution, but failed to find the reference Nick
cites... Would it not make more sense to leave the second -substr()- free to
take a month consisting of one digit or two by replacing "2" with a dot?

Martin Weiss suggested a solution which worked fine. Rose's problem was
left unexplained, however, yet the explanation is given directly in the
help for -dates_and_times-.
For functions like -monthly()-,
"The pair of numbers to be translated must be separated by space or
punctuation. No extra characters are allowed."
As Rose's dates are run together, this condition is not satisfied.
g date2=monthly(substr(date, 1, 4) + " " + substr(date, 5, 2),"YM")
would have been a direct solution. Where someone has seen fit to put
year and month together, we insert a space between them.

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 ?
