Santa’s Labyrinth

The #v0 language is intended for novice programmers. With this January 8th release of Adventurebot 3000, more experienced programmers can use a lower-level, but more flexible programming environment, (v1), a variant of the uxntal language and computer.

Here is a sample (v1) program, to solve the room in #5, the claw machine:

(v1)
(every v1 program begins with the line "(v1)",
 including parentheses)

~lib/robot.tal
(
    the robot.tal library contains routines that
    map more-or-less to the #v0 movement
    and detection commands; for example
    the routine at ;rlib-forward operates much
    like the "forward" command in v0.
