Thanks Mark S. A query, does "<$list filter="0001 0002 0003 ...etc... 4000 +[random[1]]" variable="num" >" mean i'd have to literally enter 4000 numbers? If so, that looks like asking for trouble.
Could it not be calculated from a spawned random? I wasn't actually thinking of using Tobias' solution because it seemed more focused on Tiddlers that exist. What I need is only random creation of a number between 0001 and 4000 to help create an external file link that is transitory.
