Another Array Question: Passing the address

Posts: 110
If I have one object with a VAR Servo[noparse][[/noparse]10] and later in the code, I call an object with this NewCall(@Servo[noparse][[/noparse]5) I rather presume that the servo gets the address of the 6th element in the array. Is that true ?
By way of explanation; I travel a lot and the prop hardware usually gets me strange looks at airport security, so I end up doing a lot of software work during the week and hardware work on the weekends. I'd like to test it all and find out myself, but thats just too long. So I apologize for a lot of seemingly basic questions.
Thanks

That's an interesting one. I also travel frequently and tend to carry a prop proto-board in my carry on. Mine has a 2x16 LCD and a USB lead wired to it and I carry it in a small plastic lunchbox with a clip-on lid.
I've only been asked once and then I pointed out the USB cable and told them it was a naked usb widget. Got waved straight through.
I use the USB cable to power it when I'm on a flight, but I think having it attached permanently tends to give them something they understand to look at rather than a board with nasty looking electronics on it.

Pull my finger!
That's the way it works. Then you easily access the var in the obj as Long[noparse][[/noparse]Servo(5)]
Use a [noparse][[/noparse] (insert space) Number ] to avoid crazy text when using brackets, even when posting code I think it is required to insert the space before the number.
'compile RTC bytes getRTCbyte(5,@mdy_dat,%1) 'month getRTCbyte(4,@mdy_dat[noparse][[/noparse]3'],%11) 'day getRTCbyte(6,@mdy_dat[noparse][[/noparse]6'],%1111) 'year PRI getRTCbyte(index,ptr,mask) 'parse RTC byte and convert to ASCII, store in dat string byte[noparse][[/noparse]ptr][noparse][[/noparse]0'] := RTC[noparse][[/noparse]index'] >> 4 & mask + "0" byte[noparse][[/noparse]ptr][noparse][[/noparse]1'] := RTC[noparse][[/noparse]index'] & %1111 + "0" above I used pointers that were offset by index and it worked. So I would say that @servo[noparse][[/noparse]5'] would make a pointer to the 6th element.* In order to make the index items show up in my post I had to place the second bracket after a single quote. But now you see single quotes that are not supposed to be part of the code.
