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. awk
maintains a single set
of names that may be used for naming variables, arrays and functions
(see section User-defined Functions).
Thus, you cannot have a variable and an array with the same name in the
same awk
program.
