PARSE(FIELD,REP,COMP,SUBCOMP,ESCAPE,SEG,TO) ;
;Parses the segment stored in SEG(1),SEG(2),... into TO()
;Input:
; FIELD - field separator
; REP - field repetition separator
; COMP - component separator
; SUBCOMP - subcomponent separator
; ESCAPE - escape character
; SEG - (pass by reference) the array holding the unparsed segment.
;Output:
; Function returns 1 on success, 0 on failure
; TO - (pass by reference) - the parsed values
; SEG- This input variable is deleted during the processing. If it is needs to be retained, pass in a copy!
