Mart*n quite rightly both drew attention to `=`i' - 1'. 

If that seems a little tricky, just spell it out: 

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

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?
