David Jondreau Posted September 9, 2010 Share Posted September 9, 2010 Filemaker is supposed to handle null $$ vars by not storing them at all, but if you define a $$var and then clear it in the Data Viewer, it still persists! Can't think of a possible use for this, but I thought it was interesting. Link to comment Share on other sites More sharing options...

David Jondreau Posted September 9, 2010 Author Share Posted September 9, 2010 Create a script that has: Set Variable[$$var; "ABC"] Run that script. Confirm that $$var = ABC in your Data Viewer under the "Current" tab. Double click on $$var and delete its contents. $$var persists in the "Current" tab for the length of the session in my FMP 11A v1. Link to comment Share on other sites More sharing options...
comment Posted September 9, 2010 Share Posted September 9, 2010 Double click on $$var and delete its contents. Ah, I see. I guess that goes directly inside the value "cell", bypassing any evaluation - incl. variables management. Link to comment Share on other sites More sharing options...
