The uncategorized data scanner isn't supposed to create strings or ".fill" directives that straddle labels, long comments, notes, visualizations, or ORG directives. The test for crossing an ORG directive is incomplete, and doesn't correctly handle no-op ORGs (where the new address is the same as the old address). The code generator doesn't output ORGs that are hidden inside other things, so we're not generating bad code, but it looks funny on screen and may cause problems later on. The 2004-numeric-types test has the basic .align/.fill/.bulk directive tests, and now has an extended set of tests for uncategorized data region splitting.
