Subject: Method question

Hi all,

Struggling a little with the concept of an exercise I am doing.

I have two Ruby methods, the first does a simple string replace the
second converts data to something else if the criteria is satisfied. See
example below

def processer
 field1 = data[0]
 field2 = data[1]
 field3 = data[2]
 if field3.length < 100
  field3 = field3
 else
  changer(field3)
 end
 field4 = data[3]
 field5 = data[4]
 if field5.length < 100
  field5 = field5
 else
  changer(field5)
 end
end


def changer(fieldData)
 splitData = fieldData.split(",")
 splitData.each do |output|
  p output
end

What I would like to happen is when field3 for example is longer than
100 and its data is passed to def charger, I want that method (def
charger) to split the field on all commas and then return data to
field3.

I could just put something like field3 = output, however when I get
other fields for example field5 this will not work and therefore I need
something generic that will give the data to the correct field.

I hope this makes sense. Any help is much appreciated

Regards

Stuart
