Fwd: Creating strings of binary zero characters

[Wolfgang Laun]

You can create character values in hex or octal notation. So here you have
two null characters in a string:
    BEGIN {  print "NULL:\x00NULL:\000\n"; }
Here are the NULL characters in the output:
   wlaun@terra:/tmp$ gawk -f null.awk  | od -tx1
   0000000 4e 55 4c 4c 3a 00 4e 55 4c 4c 3a 00 0a 0a
