This RPC will retrieve a list of letters from the LETTER file ($407.5),
given the letter type (required), and text to match (optional).

• TYPE
  PARAMETER TYPE:   LITERAL
  MAXIMUM DATA LENGTH:   1
  REQUIRED:   YES
  SEQUENCE NUMBER:   1
  DESCRIPTION:   

  This is the type of letter from the LETTER TYPE file (#407.6). Currently 
  the values are:
   N - No show
   A - Appointment Cancellation
   P - Preappointment Cancellation
   C - Clinic Cancellation
  

• TEXT
  PARAMETER TYPE:   LITERAL
  MAXIMUM DATA LENGTH:   15
  REQUIRED:   NO
  SEQUENCE NUMBER:   2
  DESCRIPTION:   

  This is the text used to match record entries. If 'CHY' is passed, only 
  records that begin with 'CHY' will be returned. This text match is in 
  addition to the type provided.
  

• BRIEF
  PARAMETER TYPE:   LITERAL
  MAXIMUM DATA LENGTH:   1
  REQUIRED:   NO
  SEQUENCE NUMBER:   3
  DESCRIPTION:   

  This flag indiciates that the calling application wants a 'brief' list, 
  instead of the 'verbose' list. The verbose list contains the letter text, 
  resulting in a larger returned data set. It may be advantageous in some 
  cases to retrieve a brief list, and use SDES GET LETTER BY IEN to 
  retrieve the details.
