Using a loop in a script (with variables)

[zagzebski]

I have the following script. While I included all of it the only thing I really want to accomplish is write this script once and loop through it for every month from JAN2010 through OCT2013. I have noted the variables (in red) and the table name I have created but would need to change each time I loop through.  Currently I create this same script 40+ times to get it for each month through 2013!!

For instance on the second loop though JAN2010WHERE would become FEB2010WHERE, JAN2010RETENSION would become FEB2010RENTENSION, and the table name Line_of_BusinessCube_Jan2010 would become Line_of_Business_Feb2010 and so on for each successive month.
