So maybe you do not want to compile it at all if you target an HP calculator.

That is a normal BASIC interpreter, even has a LOAD comand that is loading in memory all the programm.
It runs under Windows as DOS box, looking very like a normal BASIC interpreter.

Sorry, I didn't read your original post completely. C is very portable, but the libs that C use can be platform specific, especially I/O. Porting anything with HPGCC will require some effort if it is interactive and/or based on Windows or another platform.

Example HPGCC program (http://sense.net/~egan/hpgcc/#Hello, World):

Code:


#include <hpgcc49.h>
       
int main(void)
{
    clear_screen();
    printf("hello, world\n");
    WAIT_CANCEL;
    return(0);
}

The clear_screen() and WAIT_CANCEL are unique to HPGCC.
