Changing parameters in saprfc for Ruby

saprfc for Ruby now has the ability to pass Changing type parameters. These are an evolution of import, and export parameter types rolled into one. this functionality is available from release 0.31. This example shows the standard test RFC where COUNTER is a changing type parameter - the value is incremented on each pass:

iter = 10
rfc = SAP::Rfc.new(...)
# look up the interface definition for an RFC
i = rfc.discover("STFC_CHANGING")
i.counter.value = 0
iter.times {|cnt|
  puts "\n\n\n\n\nITERATION #{cnt + 1}\n\n\n\n"
  i.start_value.value = cnt
  rfc.call(i)
  puts "RESULT: #{i.result.value}  COUNTER: #{i.counter.value}"
}
# close the connection
print "close connection: ", rfc.close(), "\n"
