Re: Gawk - problem with hexadecimal numbers

[Aharon Robbins]

Greetings. I cannot reproduce this under Fedora Core 2 with either
gawk 3.1.4 or 3.1.5. I get the correct answer of 14.

Did you compile this yourself from sources? If not, you might
try that with the current version.

Also, what kind of locale settings do you have? That shouldn't be
an issue, but one never knows.

Thanks,

Arnold
