Arrays in `awk'
***************

   An "array" is a table of values, called "elements".  The elements of
an array are distinguished by their indices.  "Indices" may be either
numbers or strings.  Each array has a name, which looks like a variable
name, but must not be in use as a variable name in the same `awk'
program.
