I don't know SPSS, but it certainly looks long-winded here.
More importantly, my guess is that you have translated
the code appropriately -- assume that each do-if in SPSS
is executed in turn -- so what remains mysterious is what
you mean by "did not work".
-if ... else ...- is certainly _not_ the answer for
reasons explained at

6/00 I have an if command in my program that only seems
to evaluate the first observation, what's going on?

Incidentally, check out -cond()-.
replace hrolle = cond(hrolle < 200, hrolle - 100, hrolle - 200)
replace hrolle = cond(hrolle < 20, hrolle - 10, cond(hrolle < 30, hrolle - 20, hrolle - 30))
