Deletes all the messages in the WASTEBASKET folder.  When  you  EXIT
  from  MAIL  or issue a SET FILE command (to select a new mail file),
  an implicit PURGE is done to empty the WASTEBASKET folder.

  Purged message space is not available for  reuse  by  VAX-11  Record
  Management Services (RMS) until you enter the PURGE/RECLAIM command.
  An automatic PURGE/RECLAIM is done when the amount of deleted  space
  in  a mail file exceeds 32767 bytes.  (MAIL uses the CONVERT/RECLAIM
  utility to reclaim space.)

 /RECLAIM

 Releases deleted message  space  back  to  VAX-11  Record  Management
  Services (RMS) for reuse.

  Because your mail file is locked while PURGE/RECLAIM is running, you
  will  be  unable  to receive new mail.  Users attempting to send you
  mail while PURGE/RECLAIM is running will receive  an  error  message
  indicating that their message was not sent successfully.

 /STATISTICS

 Indicates the amount of released deleted message  space  in  a  short
  statistics display when you use it with PURGE/RECLAIM.
