Actually, it's the "file format" version, which is "2.4" for "legacy" stacks (ones created with MetaCard 2.6.6 and earlier or Revolution 2.6.1 and earlier), and "2.7" for "normal" stacks (ones created with MetaCard 2.7+ and Revolution 2.7+). Let me explain: Keep in mind that when RunRev picked up MetaCard and started putting out new versions of Rev, there was a disparity between the engine version and the published version by RunRev, because MetaCard was at 2.5 at the time of acquisition, and Revolution (the IDE) was only at 2.1.2 (I believe). From this point until version 2.7, Revolution was playing "catch up" to the MetaCard version number, and the only way to tell the difference was that Revolution had (has) a custom function called revAppVersion() that would give you the Rev version; asking for "the version" gave you the *MetaCard engine* version. For example, in Rev 2.1.2: put revAppVersion() --> 2.1.2 put the version --> 2.5.1 Now in addition to the *engine* version, and the *IDE* version, there's also the *file format* version, which is when something major changed to the file format that made it significantly different than the one before it, causing warnings about moving between the formats, and also creating the situation where a stack in the newer file format could not be opened by an older engine. The last two major file format changes happened in MetaCard 2.4 and Revolution 2.7, which is why the *file format* version is 2.4 or 2.7. Currently, there's the ability to save a stack from Rev 2.7 in "legacy" format, which gives it the 2.4 file format, or "normal", which gives it the 2.7 file format.
