Subject: convert String "1;2;3;4;5;" to Array [1, 2, 3, 4, 5]

I'm trying to convert a String of numbers that are separated by
semicolons to an Array---totally for fun, to stretch my ruby
understanding, fyi.

I use the Array in a while loop which does work when the Array looks
like = [1,2,3,4,5,...]---so that part is working. But I want to use ruby
to
convert a String = "1;2;3;4;5;6;7;8;9;10" into an Array [1,2,3,4,5,...]
so
that I can use these values.

I've tried many a method, but can't seem to get the desired result; I've
tried gsub(/\;/, ","), eval (), and others.

##########

raw_data = "1;2;3;4;5;6;7;8;9;10"
data = raw_data.split(/\;/) #but this gives ["1", "2", "3", "4", "5",
"6", "7", "8", "9", "10"], not [1, 2, 3,...]

#data = [1,2,3,4,5,6,7,8,9,10,11,12] # this is the desired result

boundary = 1
ending_boundary = 13
interval = (ending_boundary - boundary)/3

while boundary < ending_boundary
    print "For the class #{boundary} to #{boundary + interval}, "
    print "the group is: "
    puts data.select{ |x| x >= boundary && x < (boundary + interval)
}.size
    print data.select{ |x| x >= boundary && x < (boundary + interval)
}.join(' ')
    boundary = boundary + interval #increase the boundary to the next
class
    print ".\n"
end
