The grammar is the same as
PALO ALTO TinyBASIC by Li-Chen Wang
Except 4 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]

(3)SYSTEM command
SYSTEM return to CP/M.

(4)Other some beyond my expectations.
