This started as a
20-line challenge entry but then I decided to add pull down menus and it ended up nearer 200 lines. You can now stack multiple commands per line without needing 3 digits for each parameter (except in "colour" commands). You can nest multiple repeat commands per line up to I think 19 repeats. It has an online help with 4 example programs. Also, so you can copy and paste and edit in comfort you can write programs in notepad and load them into the program, as well as saving programs to a text file. Anyway, you can
download here
