st: i and i-1 in forvalues command

[Florian Wakolbinger <wakolbinger@drei-e.at>]

Dear all,

I want to categorize the subjects in my dataset according to the number 
of hours they work. I define say 5 kategories with kat0, kat1, kat2,..., 
kat5 being the highest number of hours in each category.

Then I categorize using

gen kat = .

forvalues i = 1/5 {
  replace kat = `i' if hour > kat`i-1' & hour <= kat`i'
  }

the problem is I apparently cant write i-1 between ` and '

does anybody know how I can access i-1 while the loop is in state i?

thanks for your help!
best, Florian
