Hi Crypton,
Sorry for the late reply.
Had no internet connection durring the weekend
(shake fist @provider).

I wrote a little code snipet with:

hbar(0, 0, 200,.....
(its somemthing like this, sry I have to access to my workstation here)

Its kinda old, and its not in the manual but it is exactly what you were looking for.
I tested it also with decimals and it works very well.

As soon as I have my internet connection up and running I can post a little code snippet.
You can try to find the hbar / vbar instrunctions, I couldnt find it in the manual. Ive found it in an old project where I had a healthbar.

maybe soemeone else knows the exact syntax of hbar/vbar.

cheers
