BUILDSEG(HLMSTATE,SEG,TOARY,ERROR) ;Builds the segment from the individual values
;Input:
; HLMSTATE() - (pass by reference, required) Used to track the progress of the message. Uses these subscripts:
; ("HDR","FIELD SEPARATOR")
; ("HDR","ENCODING CHARACTERS")
; SEG() - (pass by reference, required) Contains the data. It must be built by calls to SET^HLOAPI prior to calling $$BUILDSEG.
;
;Note#1: The '0' field must be a 3 character segment type
;Note#2: ***SEG is killed upon successfully adding the segment***
;
;Output:
; Function - returns 1 on success, 0 on failure
; TOARY (pass by reference) This will return the segment in an array format TOARY(1),TOARY(2),... For segments that are shorter than the MUMPS maximum string length, there will be only TOARY(1)
; ERROR (optional, pass by reference) - returns an error message on failure
