>nul, not a valid command

[Ed Dyreen]

☺
What's wrong here

Code: Select all

set "@Debug.on=set "@DNul=""
set "@Debug.off=set "@DNul=^>nul""
set "@TraceIn=call %%@DNul%% echo.hello world"

%@Debug.on%
%@TraceIn%
%@Debug.off%
%@TraceIn%

output:

Code: Select all

>nul wordt niet herkend als een interne
of externe opdracht, programma of batchbestand.

Meaning, not a valid command. Think I'm going crazy

This seems to work but it isn't good enough, the '>' really needs to be inside @DNul.

Code: Select all

set "@Debug.on=set @DNul=con"
set "@Debug.off=set @DNul=nul"
set "@TraceIn=echo.hello >!@DNul!"
setlocal enabledelayedexpansion

I've tried everything I can think of, I'm running out of ideas...
