Re: [bug-gawk] An gawk problem.

[Aharon Robbins]

Hi.

You can send these kinds of mails to address@hidden, in the future.
I am cc'ing there.

And your English is good enough that I understood.

I need to know the following:

1. What version of gawk are you using?  Use    gawk --version   to find out.
2. What operating system are you using? Windows (if so, which version),
   Linux, other?
3. Did you compile gawk yourself, and if not where did you get it from?

In any case, what you describe should not be happening.

Please let me know the answers to the above questions and then we
can proceed.

Thanks,

Arnold
