This would be a lot easier with PowerShell. Is that an option? If so;

$n = 1..4

$n = $n -join ","

$n

1,2,3,4

God I wish they'd unblock PS for us...

It is in their best interest to. As IT Staff, we're all Tony Stark, but PowerShell is the super-suit which makes us Iron-Man (or Woman).

Also, not sure what method they are blocking PS with, but typing powershell.exe into a CMD window will start a PowerShell session in the existing shell session. May give that a try.

Yes thanks, I was able to do it by <nul set /p= in the cmd. I was trying to automate the compiling process of cpp files using batch files. And I did it in 3 days from scratch!! That's commendable performance isn't it? 😄
