Width Control of ChooseBox inside the INPUT instruction

[Bob Frazee]

I am trying to control the width of the Choose field inside the INPUT instruction using the format shown in the calculator help file, {var_name, {choose_items}, [{pos}]}. It doesn't seem to matter what I put in the "pos" field, the field width remains the same. Is this by design, or another gotcha, that will be fixed in a future update? Thanks
