Re: problem in GNU Awk 3.1.3 - comparison does not work

[Aharon Robbins]

Greetings.

I suggest you read the gawk documentation on comparisons.  The values
in this case are treated as strings for comparison, thus "4" is greater
than "12".

You can add the line

        lmonth = lmonth + 0

after the

        lmonth = sprintf("%d", sa[2])

or change it to

        lmonth = sprintf("%d", sa[2]) + 0 # force numeric

to force lmonth to be a numeric value.
