the @ character should not be used unless the variable is an instance
variable (@x) or class variable (@@x)

you're showing your perl background

the character string must be enclosed within parentheses

aa="LIN*EDIA000005*000000570*570*0697*RC*SHEPLER'S EXCLU*100*SHEPLER'S
\         # '\' instructs ruby to ignore the carriage return
EXCLUSIVE*6042142403*SHEPLERS COGNAC HORNBACK CAIMAN\
TAIL*20070719*20070719**02*724178914197******070\
A**********************50384~"

puts "aa is a #{aa.class} of length #{aa.size}"
ab = aa.split('~')
puts "ab is #{ab.class} of size #{ab.size}"


ab.each do |a|
  puts "a is a #{a.class} of length #{a.size}"
  b = a.split('*')    # no need to escape unless you use a regex
split(/\*/)
  puts "b is a #{b.class} of size #{b.size}"
end

aa is a String of length 195
ab is Array of size 1
a is a String of length 194
b is a Array of size 44                          b,size or b.length
gives the size of the array
