# Sample : put() : Put a message to a queue with a Refernce header
#          Open the queue so that multiple puts can be performed
#
require 'wmq/wmq'

# The Rules Format header (MQRFH) allows a list of name value pairs to be sent along
# with a WMQ message. These name value pairs are represented as follows on the "wire":
#   Name1 Value1 Name2 Value2 Name3 Value3
#   
# Ruby WMQ converts the above string of data into a Ruby hash by
# using the name as the key, as follows:
# data = {
#    'Name1' => 'Value1',
#    'Name2' => 'Value2',
#    'Name3' => 'Value3'
# }
# 
# Since a name can consist of any character except null, it is stored as a String
# 
# Note: It is possible to send or receive the same Name with multiple values using an array.
#   E.g.   Name1 Value1 Name2 Value2 Name1 Value3
#   Becomes:
# data = {
#    'Name1' => ['Value1', 'Value3'],
#    'Name2' => 'Value2'
# }
# 
# Note: Since a Hash does not preserve order, reading a Rules Format Header and then writing
#       it out immediately again could result in re-ordering of the name value pairs.
#
