Re: Parsing multiline string line by line

[Nelson H. F. Beebe]

List member goncholden <goncholden@protonmail.com> asks about
splitting a multiline string into lines for separate processing.  Here
is an example:

        % cat foo.awk
        BEGIN {
        str=" \n \
        Here is the first line \n \
        Another line \n \n"

            n = split(str, parts, "\n")
            for (k = 1; k <= n; ++k) printf("line[%d] = [%s]\n", k, parts[k])
        }

        % awk -f foo.awk
        line[1] = [ ]
        line[2] = [ Here is the first line ]
        line[3] = [ Another line ]
        line[4] = [ ]
        line[5] = []

The split() function is extremely useful, and worthy of study in the
gawk manual or awk books.
