Positioning Cursor on TV

MikeS

I just finished putting together my first Propeller spin program. It displays the output of the PING on a TV. My question is how do you position the cursor on a TV?
I want to continually monitor the PING but want the output to remain on the same line of the TV screen. As I have it now I get subsequent repeating lines down the screen.
I tried to attach (upload) the program to this post but I kept getting an error.
Thanks,
MikeS

text.str(string(1,$b,5))
text.dec(abc)

would put abc at row 6

the 1 resets the start position

more info can be found within the tv text object.

Hi Mike,

Your better off using TV_Text if you want to position Text at a specific place on screen.

TV_Terminal as far as I know will only bring the cursor back to the home position (upper left).

The command for that is:
term.out($00)

If you click "Documentation" when you have any of these pre-written drivers open in the Prop Tool, there is usually some desription of how to do stuff.

Also you can print strings on the screen like:
term.str(String("Hello"))

you dont have to have it in a DAT block

Erik,
Thanks for the help, I found the syntax in the TV_Text file.
