Using Lists - LB and LI
I have a repeatable field within HL7 that I want to create a List from. Do I have to initialize the List by using $LB, or can I just use $LI to keep adding on to the end of the list as it is looping through the field?

USER>kill list for i=1:1:10 { set $list(list, *+1) = i } zw list list=$lb(1,2,3,4,5,6,7,8,9,10)Is this what you're after?
do I have to call
foreach(<field>) { set list = $LB(<field>) }or can I
foreach(<field>) { set list= $LI(<field>,<counter>) }I'm not familiar with HL7 processing, but I suppose should be like this
foreach(<field>) { set $list(list, * + 1) = <field> }if you need to create list, than $list on the left side, with *+1 as position, to add to this list, and the right side, any value you would like to add to the list
Within a BP, you can create a Variable list, and just call
do context.<variable>.Insert(<value>)and it will add it to the list. Now that I have that piece working, I need to figure out how to extract that list so I can create some logic around it.
