	W @IOF,!!,"This option will allow you to purge:"
	W !,"1. individual or a range of DSS extracts, or"
	W !,"2. data that resides in the ""holding files"" for the IVP and UDP extracts."
	W !,"3. data that resides in the ""holding file"" for the VBECS extract"
	W !!,"Care must be taken for several reasons:"
	W !!,"-  You can purge ANY existing extract.  This includes transmitted and non-"
	W !,"   transmitted extracts as well as extracts that did not run to completion"
	W !,"   due to errors or system problems."
	W !,"-  Choosing a range of extracts (or a broad date range for the ""holding"
	W !,"   files"") could mean an excessively large number of records and be very"
	W !,"   CPU intensive.  Please be sure to queue this purge for off-hours and"
	W !,"   limit the number of extracts to be purged per a single queued session."
	W !,"-  The IVP, UDP and VBECS ""holding"" files are intermediate files that"
	W !,"   are populated ""realtime"" by inpatient pharmacy and VBECS activity. These"
	W !,"   files are then used to generate the IVP, UDP and VBECS extracts and CANNOT be"
	W !,"   recreated. Once they are purged for a date range, extracts can no longer be"
	W !,"   generated for that time period."
