Hi, I see that there are built-in functions in gawk that can accept
arbitrary number of arguments. How to define one with accept arbitrary
number of arguments by the users? Thanks.

       and(v1, v2 [, ...]) Return  the bitwise AND of the values
provided in the argument list.  There
                           must be at least two.

nope, you'll have to loop on the list

echo 127 63 255 61 7 | awk '{r=$1;for(i=2;i<=NF;++i)r=and(r,$i);print r}'
