Hello,

I have issue in this power shell command. I would retrieve table item. 

@echo off
$MonTableau = @("admin","trans","references","dico")
foreach ($data in $MonTableau)
{
@echo $data
}
pause

but cmd prompt not recognize anything. 

I use windows7 

Your are using a mix of powershell and cmd commands in the cmd shell. They are completely different things. Powershell has its own console.

PowerShell does not support that syntax and CMD shell or batch does not support that syntax.
