Get screen width (in characters) in batch file?

[Kenny McCormack]

In a batch file, I want to get the width of the screen (e.g., 80, in the
normal case) into a variable. This is, e.g., the number displayed in the
"Properties" of the Command Prompt window - as the "screen width".

I know how to get this is in a regular programming language (e.g., C or
C++), using a Win32 API call, but I don't know of any easy way to get it
purely in batch (CMD.EXE).

Also, not interested in any solutions that involve things like PowerShell
or VBA. As I said, if it requires going to a regular programming language,
I already know how to do that.

Any ideas?

MODE CON: COLS=xx LINES=yy

I think you misread the word "get" as "set".

Well, the clue is there; parse the output of "mode con:" for "Columns:"

Bah, and indeed, Humbug.

MODE > [file]
FIND "Columns" [file] > [file 2]
SET /P _Col=<[file 2]
SET _Col=%_Col:Columns: =%
etc

Sure. What's my fee?

Indeed. Thanks.

"mode con" delivers the goods.

@echo off
for /f "tokens=2" %%i in ('mode con:^|find "Columns"') do set /a n=%%i
echo %n%

Sorry, I was a bit grumpy earlier;

I'm also a bit rusty; no need for the 'delims= '

for /F "tokens=1,2" %i in ('mode con:') do if %i == Columns:
set cols=%j
