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?

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

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

Indeed. Thanks.

"mode con" delivers the goods.

Sorry, I was a bit grumpy earlier;

@echo off
rem mode con: cols=97
for /F "tokens=1,2 delims= " %%i in ('mode con:') do if %%i==Columns:
echo cols=%%j

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

set cols=%j
