Off topic:awk help to print lines when the columns are non zeros

Question

[geneart$$]

Hi I have a file with the following format:

filename is foo.txt

abcd 1 0 0 2
abef 2 0 0 0
able 2 1 2 0
able 1 0 0 0
efgh 0 0 0 0

I wrote an awk script to delete the row with all columns with 0. But I am getting syntax error. SO I am sure this is very simple.

Please can anytime help me fix this?

awk 'BEGIN{i=1; While($2==0)($3==0)($4==0) {print $0} }' foo.txt
