Other Features of `awk'
=======================

   The `awk' language provides a number of predefined, or "built-in",
variables that your programs can use to get information from `awk'.
There are other variables your program can set as well to control how
`awk' processes your data.

   In addition, `awk' provides a number of built-in functions for doing
common computational and string related operations.  `gawk' provides
built-in functions for working with timestamps, performing bit
manipulation, and for runtime string translation.

   As we develop our presentation of the `awk' language, we introduce
most of the variables and many of the functions. They are defined
systematically in Note: Built-in Variables, and Note: Built-in
Functions.
