Variables/ Registers / Arrays

Variables / Registers / Arrays #V

Command group to execute calculations and logical operations. With the help of the string files, internationalization (multiple languages) can be realized. There are registers for numbers and strings (can record characters up to 200), integer registers use signed 32-bit, floating-point registers use 23-bit mantissa, 8-bit exponent, 1-bit signed.
