Re: [bug-gawk] Feature suggestion - function abs(X)

[arnold]

Hi.

Thanks for the suggestion.  I agree it'd be useful, but I don't
really wish to keep extending the gawk core. You can easily avoid
the need to keep retyping the function by putting it in a separate
file and setting the AWKPATH directory to include the directory
holding it. You can then either use an additional `-f abs.awk' on the
command line or

        @include "abs.awk"

in your awk programs.

Thanks,

Arnold
