"|&" co-process operator fails(WinNT4.0)

[Paranji, Sanjay]

Hi 

I am attempting to use "gawk" to communicate between a PC and a Unix host.
As a test I wrote the following prog which starts a service to listen for a
{filename} argument. While I could launch the service on a UNIX box with
gawk 3.1, I could NOT launch this on the PC with gawk 3.1. I installed gawk
on the PC myself by getting "djgpp" binaries, the PC is loaded with WinNT
4.0 OS. The prog fails with the msg

fatal: '|&' not supported

All the docs seem to suggest that co-process operator works under the
Microsoft Win environment. Am I missing something?. Thanks and Rgds, Sanjay

     close(cmd); close(srv)
  }
