use the INTNX function (within PROC SQL or data step):
New_Date = INTNX("month", Date_A ,-6, "[alignment]");

where alignment is:
BEGINNING
MIDDLE
END

using today's date (11 Apr 2012),
BEGINNING gives you 01 Oct 2011
MIDDLE gives you 16 Oct 2011
END gives you 31 Oct 2011

so you have to decide which date you are interested in ;)
