Robot KAREL

Robot Karel knows the commands step, left, right, pick up, put down, paint and wait. In this version of the language, you can also use integer variables, multidimensional arrays, arithmetic and logical operations, procedures, and functions with parameters when programming.
> The program includes a text editor, a compiler, a compiled code interpreter and a debugger. The environment is very similar to that of Borland Pascal. It can be controlled via menus or keyboard shortcuts. The editor can do everything that regular editors can do (Copy, Paste, Find, Replace, Undo, Redo, Indent, ...).
