Below is a quick attempt at doing some things in ruby that I have been doing
in perl.
Question 1 how can I save and then reuse the functions that are defined in
other applicaitons.
Question 2 how can I rewrite some this in a more ruby way

Itterating over an array and then having to have a counter variable to make
"in-place" changes seems a little overkill and I am pretty certian there is
probaly a better way.

I have a lot of pipe delimented text files that I work with that contain
some standard thing that always get converted. Dates and Numbers to name a
few.

Thanks for you time !! :)

def splitpipe( string )
  count = 0
  record = string.split('|')
  record.each do |element|
    element = element.strip
    element = formatnum(element) if element =~ /\d?\.\d+/
    element = convertdate(element) if element =~ /^\d\d\/\d\d\/\d\d$/
    record[ count ] = element
    count += 1
  end
end

def formatnum(num)
  num = num.to_f
end

def convertdate(date,type=0)
  datearray = date.split('/')
  if datearray[2].to_i > 90
    datearray[2] = "19" + datearray[2]
  else
    datearray[2] = "20" + datearray[2]
  end
  if type == 'human'
    date = datearray.join("-")
  elsif type == 'array'
    datearray
  else
    date = datearray[2] + datearray[0] + datearray[1]
  end
end

salesfile = File.new( FILENAME, 'r' )
worksign = 1
objects = Array.new
salesfile.each_line do |line|
  record = splitpipe( line.gsub(/^H:/,'') )

  if record[1] == 'C' or record[2] == 'Y'
    worksign = -1
    record[9] = record[10] if record[1] == 'C' #Set qty shipped if credit
work around
  else
    worksign = 1
  end
  record[6] = record[6] * worksign
  record[7] = record[7] * worksign
  record[9] = record[9] * worksign
  record.each { |e| puts e }
  exit
end
salesfile.close
