 XCSB is a structured BASIC and the compiler produces very efficient code.

The following XCSB code illustrates the point

    proc inline write_bit(ubyte *ptr, ubyte id)
        ubyte    x
        if ptr == &PORTA then
            x = 1
        else if ptr == &PORTB then
            x = 2
        else
            x = 3
        endif
    endproc

    proc main()
        write_bit(&PORTA, 3)
    endproc

This code compiles to just 2 instructions

    0069                    main

    0069    30 01                   movlw   1
    006A    00 A6                  movwf   x_write_bit_func_local

    006B                    main_func_exit_point
