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.

String file / multilingualism

"Hello World" is placed in 4 different languages. It must be ensured that the selected font supports all necessary characters. In the following example "Arial Unicode MS" was used. The commands below assume that the string files (Chinese.txt, English.txt, Cyrillic.txt and German.txt) are already available on FLASH in the project path in the string's subfolder:

...
