Over-write previously printed line

[pjc30943]

Is there a terminal command supported in zbasic to print pending characters at the start of the current line? I.e., displaying a changing number in place without entering to a new line for each update.
I know this is not supported by debug.print, but are there any COM1 tricks?

I've done quite a bit of work using Hyperterminal and ZBasic. Most terminal emulation software (hyperterminal included) is actually emulating a DEC VT100/VT220 terminal. As such, you are welcome to use any number of escape codes to manipulate the screen/cursor/text.

In effect, you need only change your method of control. If the processor cannot output the correct formatting, then use the receiving end's abilities to achieve the same effect. I've used this method for menu driven applications written in ZBasic with excellent results. It's simply a matter of defining a few constants that contain the appropriate escape codes and embedding them in the debug.print statements.

Unrelated to your actual question, but worth mentioning here; be cautious when using debug.print in application code. There's a reason why it starts with 'debug'. A better method would be to open a com channel and write directly to the channel's output queue.
