3BHS(HL,BID,RESULT,SECURITY,MSA) ;Create a BHS Segment for an Outgoing HL7
4 ;Batch Message
5 ;
6 ;This is a subroutine call with parameter passing that returns an HL7
7 ;Batch Header (BHS) segment in the variable RESULT (and possibly
8 ;RESULT(1) if the BHS segment is longer than 245 characters). If the
9 ;required input parameters HL or BID are missing, RESULT is returned
10 ;equal to null
11 ;
12 ;Required Input Parameters
13 ; HL = The array of values returned by the call to INIT^HLFNC2
14 ; BID = The Batch Control ID to be included in the BHS segment.
15 ; The Batch Control ID for the batch is returned by the
16 ; call to CREATE^HLTF.
17 ; RESULT = The variable that will be returned to the calling
18 ; application as described above
19 ;Optional Input Parameters
20 ;SECURITY = Security to be included in field #8 of the BHS segment
21 ; MSA = Three components (separated by the HL7 component separator
22 ; character) consisting of the first three fields in the
23 ; MSA segment. This variable is required if the message
24 ; you are building is a batch acknowledgment
25 ;
26 ;Check for required parameters
