10 ; Put the HL7 record into an array that is easier to work with
11 ; (Something similar to table)
12 ;
13 ; This got a little bit tricky since some segments repeat and
14 ; segment within those segments repeat. Some arbitrary limits
15 ; were imposed to be able to handle this.
16 ; 1) A segment may only repeat 9 times. (no more than 9 IN1's)
17 ; 2) Only 4 repeating segments may be within each other.
18 ; IN1 could repeat 9 times. Within IN1, IN3 can repeat 9 times.
19 ; Another segment could repeat within the IN3, and another within
20 ; that one, but that's it.
