Jan --

I have no problem redirecting stderr to a file using v1.12.maint3.

Here's my GO32 info:

[c:\kasper\src\test]go32
go32 version 1.12.maint3 Copyright (C) 1994 DJ Delorie
Lowest version I can run is 1.08
go32.exe usage: go32 [-d {debugger}] [{program} [{options} . . . ]]
go32.exe build time was Sun Dec 18 16:36:42 1994
DPMI memory available: 7728 Kb
Swap space available: 120260 Kb

If I want to redirect the stderr output from 'test.exe' to the 
file "test.txt" I type this command line:

test.exe >& test.txt

The ampersand ('&') character indicates that stderr, not stdout,
is to be redirected.
