st: making new variables for each obs

[=?ks_c_5601-1987?B?sei6tLjwKEJ5dW5nbW8gS2ltKQ==?= <bmkim@kgsm.kaist.ac.kr>]

Dear All

In my dataset,
each observaion has 23 variables ( year  name  fiscalyear  v1  v2  v3  .........  v20 )

I'd like to make vars of standard deviation of sequential 10 variables.

in other words,
                                                                                       new variables
                                                                                         -----------
   standard deviation of 10 variables  ( for v1 to v10 )  -->   std1
   standard deviation of 10 variables  ( for v2 to v11 ) -->    std2
   standard deviation of 10 variables  ( for v3 to v12 ) -->    std3
    .
    .
    .
    .
   standard deviation of 10 variables  ( for v11 to v20 ) -->  std11

how can i do this?? please teach me ..
i'm very new to stata.

I greately appreciate.. Thanks..

Sincerely yours
