Subject: st: simple problem with local macro

Dear Statalisters,

I have a simple question about a local macro, as illustrated in this example.
***************************************
. clear

. set obs 3
obs was 0, now 3

. gen x = _n*10

. gen str10 a_rang=""
(3 missing values generated)

. forvalues i=10(10)30 {
  2.         local a  `i'+9
  3.         disp `a'
  4.         replace a_rang="`i'" + "-" + "`a'" if x==`i'
  5. }
19
(1 real change made)
29
(1 real change made)
39
(1 real change made)

. list, clean noobs

     x    a_rang
    10   10-10+9
    20   20-20+9
    30   30-30+9
***************************************************************

I want the a_rang variable to be "10-19", "20-29", and so on, as it
appears it would be when I -display- it.  Even with my rudimentary
knowledge of local macros, I can get around the problem by, for
example, defining another local macro equal to a.  But it seems there
should be a direct way to accomplish this in the -replace- command
above, to include the numeric value of local macro a rather than the
"`i'+9" string.

Thanks,
David Ward
