POKE Return Codes

The POKE command produces these return codes:

0

The command executed successfully.

4

The command did not execute because the virtual terminal is not defined or is disabled.

12

The command failed, probably because it specifies an invalid row/column value. Either the row or the column is larger than the screen size.
