BHS(HL,BID,RESULT,SECURITY,MSA) ;Create a BHS Segment for an Outgoing HL7

 ;Batch Message

 ;This is a subroutine call with parameter passing that returns an HL7

 ;Batch Header (BHS) segment in the variable RESULT (and possibly

 ;RESULT(1) if the BHS segment is longer than 245 characters).  If the

 ;required input parameters HL or BID are missing, RESULT is returned

 ;equal to null

 ;Required Input Parameters

 ;      HL = The array of values returned by the call to INIT^HLFNC2

 ;     BID = The Batch Control ID to be included in the BHS segment.

 ;             The Batch Control ID for the batch is returned by the

 ;             call to CREATE^HLTF.

 ;  RESULT = The variable that will be returned to the calling

 ;             application as described above

 ;Optional Input Parameters

 ;SECURITY = Security to be included in field #8 of the BHS segment

 ;     MSA = Three components (separated by the HL7 component separator

 ;             character) consisting of the first three fields in the

 ;             MSA segment.  This variable is required if the message

 ;             you are building is a batch acknowledgment

 ;Check for required parameters
