"4.1 add" bullet 3 reads (when completing the introductory sentence) ... the target location MUST reference ... o An element to add to an existing array. I think this is incorrect; the target location is the array and the "value" is the "element to add to an existing array". I suggest: ... the target location MUST reference ... o An existing array. -- David J. Biesack | Principal API Architect, SAS | @davidbiesack | 919-531-7771 | www.sas.com
