Karel's Programming Language
How can I write a simple Karel program?
The following simple program can actually be run by Karel:
BEGINNING-OF-PROGRAM
BEGINNING-OF-EXECUTION
turnoff
END-OF-EXECUTION
END-OF-PROGRAM
See if you can type this program into the editor window and get him to execute
it.
He won't do much of course, except turn himself off.
What simple things can Karel do?
Karel can move, turnleft, pickbeeper,
putbeeper, and turnoff.
Each of these words is a primitive instruction that can appear in a Karel
program.
How can I get Karel to do more than one thing in a program?
Karel can carry out a sequence of instructions if they are written down
in sequence.
Thus, the following program will get Karel to move once, turn left, then
turn off:
BEGINNING-OF-PROGRAM
BEGINNING-OF-EXECUTION
move
turnleft
turnoff
END-OF-EXECUTION
END-OF-PROGRAM
