MODE CON:...

[miskox]

I wanted to (for fun) have a DOS window of size LINES=1, then display some text, expand the window to LINES=2, display more text etc. (so dynamically increase the window size).

Here is the code:

Code: Select all

@for /L %%f in (1,1,30) DO @mode CON: COLS=80 LINES=%%f&@echo THIS IS IT

And the result is not as expected because MODE clears the screen.

Instead of

Code: Select all

THIS IS IT
THIS IS IT
THIS IS IT

I have

Code: Select all

THIS IS IT

For fun only. Not really of any use (at the moment).

Could it be that the 'mode con' moves the cursor to the top left corner every time?

This produces a similar effect, increasing the window size with each line of text, but the screen is cleared with noticeable flicker before displaying each set of lines.

Code: Select all

@echo off
@for /L %%f in (1,1,31) DO @mode CON: COLS=80 LINES=%%f&for /L %%g in (1,1,%%f) DO @echo THIS IS IT
