5PARSE(FIELD,REP,COMP,SUBCOMP,ESCAPE,SEG,TO) ;
6 ;Parses the segment stored in SEG(1),SEG(2),... into TO()
7 ;Input:
8 ; FIELD - field separator
9 ; REP - field repetition separator
10 ; COMP - component separator
11 ; SUBCOMP - subcomponent separator
12 ; ESCAPE - escape character
13 ; SEG - (pass by reference) the array holding the unparsed segment.
14 ;Output:
15 ; Function returns 1 on success, 0 on failure
16 ; TO - (pass by reference) - the parsed values
17 ; SEG- This input variable is deleted during the processing. If it is needs to be retained, pass in a copy!
