''MicroWorlds'' is a program that uses the Logo programming language, a dialect of Lisp programming language. It uses a ''turtle'' object which can be moved around, given commands, and eventually make shapes or even an animation. It is part of a large set of dialects and implementations of Logo originating from the invention of Seymour Papert and aimed at triggering the development of abstract ideas by children through experimentation. As a tool for learning, Logo is flexible and provides immediate feedback; it is both accessible to young users and robust enough to create sophisticated projects. In original versions of Logo, Papert created a large 'turtle' that was programmed to move around the room by providing commands via the computer. ''MicroWorlds'' is made by LCSI, and can be used with Windows and Mac. ==Syntax== The following is an example of something written in Logo:
In the example above, the user has gone into a part of the program called the procedure page, which allows for longer series of commands, and therefore more complex programs can be written. In this program, the cursor moves forward 90 units, turns left 90 degrees, right 180 degrees and then moves forward 4999 units. Another example is:
In this example, the user makes a dialog box appear, having the text of whatever is inside the brackets. In this case, the box would have "Hi!" written on it. Commands can be written in one of two ways: using the procedures page or the command module. The command module allows for instructions to be executed immediately, whereas the procedures page holds instructions that are able to be referenced at any time (using the name written after the word "to" at the beginning of a procedure). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MicroWorlds」の詳細全文を読む スポンサード リンク
