> put "data" into tArray["key1"]["key2"]; answer the value of tArray["key1”] > - returns EMPTY (so this works) Correct put "data" into tArray["key1"]["key2"]; answer tArray["key1”] is empty - > returns FALSE (it should return true IMHO) Because it is not empty. It has a nested array in it. If it where empty (TRUE) then it would be void of all data of all types. put "data" into tArray["key1"]["key2"]; answer tArray["key1”] is an array - > returns TRUE (so not helpful) tArray is an array; tArray["key1"] is an array (because it has ["key2"] within; tArray["key1"]["key2"] is not an array (unless you put an array into it) To make this clearer: put "hello" into tArray -- tArray is not an array put tArray; // returns "hello" tArray contains a value = true tArray is empty = false -- it contains a value tArray["key1"] is empty = true -- it does not exist tArray["key1"]["key2"] is empty = true -- it does not exist put "hello" into tArray["key1"] -- tArray is an array ; tArray["key1"] is not an array put tArray; // returns empty put tArray["key1"]; // returns "hello" tArray contains a value = false tArray["key1"] contains a value = true tArray is empty = false -- it contains an array tArray["key1"] is empty = false -- it contains a value tArray["key1"]["key2"] is empty = true -- it does not exist put "hello" into tArray["key1"]["key2"] -- ttArray is an array ; tArray["key1"] is an array ; tArray["key1"]["key2"] is not an array put tArray; // returns empty put tArray["key1"]; // returns empty put tArray["key1"]["key2"]; // returns "hello" tArray contains a value = false tArray["key1"] contains a value = false tArray["key1"]["key2"] contains a value = true tArray is empty = false -- it contains an array tArray["key1"] is empty = false -- it contains an array tArray["key1"]["key2"] is empty = false -- it contains a value put "hello" into tArray -- tArray is not an array; it has been reset to a value nullifying it's array status and values put tArray; // returns "hello" tArray contains a value = true tArray is empty = false -- it contains a value tArray["key1"] is empty = true -- it does not exist tArray["key1"]["key2"] is empty = true -- it does not exist put "hello" into tArray put "hello" into tArray["key2"] put tArray into tArray["key1"] tArray = ["key1"] > ["key2"] > "hello" ["key2"] > "hello" That just about covers it. Unless I go into super sub arrays to really blow your mind (tArray["key1","key1.1"]["key2","key2.1"]) Sean _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
