Registers reserved by default

Most of the registers used by the plugin can be modified if needed in the input parameters of the programs. But if they are not changed, the default register numbers used are those listed in Default registers.

Important

If you modify any of these private registers, you may encounter unexpected behavior.

Semaphores

Semaphores are only dedicated to KAREL programs. These semaphores are shared from one KAREL program to another. Therefore, if you use another KAREL program, make sure you do not use the same semaphore as these:

  • Semaphore 22

  • Semaphore 23

  • Semaphore 24

  • Semaphore 25

  • Semaphore 26

  • Semaphore 27

Avertissement

These semaphores are dedicated to communication synchronization. If you modify one of them, you may encounter unexpected behavior.
