 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 !!,"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 and UDP ""holding"" files are intermediate files that are"
 W !,"   populated ""realtime"" by inpatient pharmacy activity.  These files are"
 W !,"   then used to generate the IVP and UDP extracts and CANNOT be recreated."
 W !,"   Once they are purged for a date range, extracts can no longer be"
 W !,"   generated for that time period."
