Re: st:variables named T099`j'

[John-Paul Ferguson <jpferg@MIT.EDU>]

Dear Mandy,

I think that trying to manipulate j within the "if" statement on your fourth
line is causing the problem. If you first create another local macro that's
equal to that value and include it, the loop should work correctly. See below:

local j 0802
forvalue i=1/8 {
 g age`i'=2006-T099`j'
 local k = `j'-1
 replace age`i'=2006-T099`j'-1 if T099`k' > 5
 local j = `j' + 500
}

I am assuming that the first "T099`j'-1" in the "replace" line is 
supposed to be
the value of T099`j' minus 1, not the value of T099`k' as defined here. Adjust
accordingly.

Best,
