st: RE: looping up to a local macro

["Sarah Edgington" <sedging@ucla.edu>]

Michael,
What do you mean by "I can't quite get it to work"?  What problem are you
having?
Without more information about what's going wrong it is really difficult to
offer much assistance.  The form of your loop looks fine.  Maybe there's
some problem with the code in the loop itself.  Does it work if you specify
a number instead of the local macro?  You're setting the value of letters in
the same dofile as the forvalues loop, right?  If you aren't that's going to
be a problem.

Subject: st: looping up to a local macro

Dear Statalisters;

I'm writing to ask about combining loops with local values.  I have a local
macro that I need to set equal to some value, different for each database.
 Let's say, for example, 50 in one db, 100 in another.  Then I want to
preform some loop operation on all the variables from
letter1 up to letter50 or letter100 (depending on the database).  Is that
possible, with some change to the code below?  I can't quite get it to work.

local letters 100

forvalues i = 1(1)`letters' {
   quietly: rename letter0`i' letter`i'
   quietly: recode letter`i' (9=.) (2=1) (1=0)
   * more lines of code here
}

Basically, instead of copy ~400 lines of code into several dozen cleaning
files, I'd like to just set  the maximum value (50, 100, 20,
etc) for the database and have it run one cleaning file.  Thanks for any
help you can provide!
-Michael
