i get this output/error:

when i try to run this script:

BEGIN{
    level = 0;
    if(separator == "")
        separator = "#";
}

/^VW.*/{ 
    split($0, pieces, separator);
    code = pieces[1];
    if(length(code) == 2){
        print code "=" pieces[2];
    }
    else if (length(code) == 3){
        print substr(code,1,2) "." substr(code,3,1) "=" pieces[3];
    }
    else if (length(code) == 4){
        print substr(code,1,2) "." substr(code,3,1) "." substr(code,4,1) "=" pieces[4];
    }
    else {
        print substr(code,1,2) "." substr(code,3,1) "." substr(code,4,1) "." substr(code,5) "=" pieces[5];
    }
}

on a file that looks a bit like this

VW#test###
VWA#test#subtest sentence##
VWAA#test#subtest sentence#subsubtestA#
VWB#test#bsubtest##
...

it somehow manages to get past the first line but then fails.

i have no idea what's wrong, works fine with awk on windows...

great idea to port it to java, but some more documentation would be nice :-)

It looks like a bug with the split() function within Jawk.  It seems to require the 2nd arg to be a non-initialized variable of any kind.  Therefore, a work around is to add the following code prior to the last closing brace:

for (p in pieces)
  delete pieces[p];

About more docs, agreed. :)  I will put some together.  In the mean time, if you haven't checked the homepage, checkout http://www.jawk.org/.  It has the overview which provides a brief description of the Java service extensions to the language.

Regards,
Dan

Hello Dan,

that worked just fine. checked out the jawk.org homepage already, looks really interesting. however, for now i just wanted to be able to run some awk scripts on any system. and this works now, so thank you!
