MAKEIT(SEGNAME,SEGARR,FIRST245,ADTLNODE)        ;Make segment
 ;Input  : SEGNAME - Name of segment being built
 ;         SEGARR - Array continue segment data (pass by value)
 ;           SEGARR(X) = Value for sequence N
 ;           SEGARR(X,Y) = Repetition Y of sequence X
 ;           SEGARR(X,Y,Z) = Component Z of repetition Y of sequence X
 ;           SEGARR(X,Y,Z,A) = Subcomponent A of component Z of
 ;                             repetition Y of sequence X
 ;         FIRST245 - Variable to return first 245 characters of
 ;                    segment in (pass by value)
 ;         ADTLNODE - Array for continuation nodes (pass by value)
 ;Assumed: HL7 encoding chars (output of INIT^HLFNC2 or INIT^HLTRANS)
 ;Output : None
 ;         FIRST245 = First 245 characters of segment
 ;         ADTLNODE(1..n) = Continuation of segment
 ;Notes  : Validity & existance of input is assumed
 ;       : Assumes no single element contained in SEGARR is greater
 ;         than 245 characters
 ;       : Continuation nodes are added at element boundaries
