InterSystems IRIS List Structures

You can specify an InterSystems IRIS list structure (%List) to ZWRITE as a variable or an expression. ZWRITE displays a list structure as $lb(element1,element2). This is shown in the following example:

  SET FullList = $LISTBUILD("Red","Blue","Green","Yellow")
  SET SubList = $LIST(FullList,2,4)
  SET StrList = $LISTFROMSTRING("Crimson^Azure^Lime","^")
  ZWRITE FullList,SubList,StrList
