Dear Statalisters

 

I want to perform a simple procedure over 100 variables and I don’t want to enter the name of each variable one by one.

If I use the first definition of varlist (below), my little procedure works fine.  But if I used the second definition of varlist, using “-“ I get an error (procedure below).

 

How can I solve this problem?  I am sure this is very simple for most of you, but I am new trying to do these things with Stata.

My version is 7.0 updated.

 

Thanks a lot

 

Adrian

 

 

local varlist p26_1_1 p26_1_2 p26_1_3

 

local varlist p26_1_1-p26_1_3

 

tokenize `varlist'

 

 while "`1'" ~= "" {

  2. generate a1997`1'_=0

  3. replace  a1997`1'=1 if `1'==1997

  4. generate a1998`1'=0

  5. replace  a1998`1'=1 if `1'==1998

  6. macro shift

  7. }

invalid syntax

r(198);

 

end of do-file

r(198);
