Andrew,

Thanks for the prompt reply.

I have done so.

My suspicion was that the system() command in gawk was
invoking command.com rather than cmd.exe, although I
assume that the value of COMSPEC would be checked by
the gawk code.

This suspicion seems to be confirmed, at least in
part, by the following session:

C:\djgpp\home\pt>gawk -f 'BEGIN{system("ver")}'

MS-DOS Version 5.00.500


C:\djgpp\home\pt>gawk -f 'BEGIN{system("cmd /c ver")}'

Microsoft Windows 2000 [Version 5.00.2195]

C:\djgpp\home\pt>

I'm not sure what the first version is, but the
second is cmd.exe's.

To be honest I'm not sure of the version numbers, but
AFAICR I didn't have this specific problem on NT4 on
which I did use the LFN TSR.

The v2.04 versions work fine on Win98SE even with the
specific code used in my earlier examples.

Will do, thanks.
