A new version has been published including a number of enhancements, most conspicuously tracking of whether shared variables are assigned to or from in any given compile unit. This is ideal for shared variable refactoring since, among other things, it makes it very obvious which shared variables are not referenced in a compile unit. See http://www.oehive.org/node/2286 for a sample report.
Thanks Thomas for posting your updates and letting our users know about ABL2DB new versions.
