Issue I398 [lua,enhancement,resolved] New simion.VERSION variable. See simion.VERSION in "docs/lua_simion.html" for full documentation on this variable. As of 8.0.3-TEST8, simion.VERSION contains the SIMION version number string (e.g. "8.0.3" or "8.0.3-TEST8"). Implemented in 8.0.3-TEST8 As of 8.0.4-TEST19, simion.VERSION contains a version object and permits comparisons such as assert(getmetatable(simion.VERSION) and -- optional for compatibility simion.VERSION >= simion.VERSION '8.0.5-TEST19', "version 8.0.5-TEST19 or above required") Update 8.0.5-TEST27: Fixed: tostring(simion.VERSION(s)) now works properly.
