The grammar is the same as
PALO ALTO TinyBASIC by Li-Chen Wang
Except 3 point to show below.

(1)The contracted form of the description is invalid.

(2)Force abort key
PALO ALTO TinyBASIC -> [Ctrl]+[C]
TOYOSHIKI TinyBASIC -> [ESC]
NOTE: Probably, there is no input means in serial monitor.

(3)Other some beyond my expectations.
