Overwritten lines in console

[dghoskins]

In printing data lines to a console window, the printed lines seem to wrap around and overwrite previous lines.  For example, in the following code:

Code:

OPENCONSOLE

FOR temp = 1 TO 500
PRINT "Line ", temp
NEXT temp

PRINT "Press any key to exit"
DO:UNTIL INKEY$ <> ""
CLOSECONSOLE
END

when I scroll to the top of the console window the top line is "Line 203".

Experimenting with the upper limit in the loop, I find that an upper limit of 297 does not wrap.

Is this a windows limit or an Emergence Basic limit?  

I found a reference to a "console_resize.eba" posting for changing the # of columns in a console but I cannot find the original posting.

Any help would be appreciated.

EDIT:  The equivalent program in Aurora shows the same behavior.

Hi Dennis,

I think you have to do a little study about "console screen buffer" and its relation to "console screen buffer's window".

What you are experiencing is the overflow of the buffer shifting out the oldest bytes.

Thanks Ficko,

That was the hint I needed.
