* Nearly all familiar BASIC commands supported (PRINT, INPUT, IF... THEN, GOTO, GOSUB, DATA, etc.)
* Lots of BASIC functions supported (SIN, COS, EXP, LOG, string functions such as LEN and MID)
* All the traditional BASIC operators (unary -, NOT, OR, AND, >, >=, <, <=, = [equality operator], +, -, *, /, ^, function(...), = [assignment operator])
* Three intrinsic data types (all 64-bit): Integer, double precision floating point, and UTF-8 string. Arrays of any dimensionality.
* Full Unicode support (UNI function replaces traditional ASC)
* Text file I/O.
* Compiles to native 64-bit asm (can use fasm or nasm as backend).
