BASICtools includes an emulator that runs on a PC without connection to any ARM CPU. We also have versions for Linux and Mac..
The syntax of this BASIC is much like the original Microsoft BASIC, QBASIC or early versions of Visual BASIC.
As part of the compile process a modified version of the C pre-processor is called that allows #include, #define, #ifdef ... #endif, #if ... #endif, #error and #warn
Support for interrupts, floating point accelerators, and multi-tasking.
