Advanced Features of `gawk'
***************************

     Write documentation as if whoever reads it is a violent psychopath
     who knows where you live.
     Steve English, as quoted by Peter Langston

   This major node discusses advanced features in `gawk'.  It's a bit
of a "grab bag" of items that are otherwise unrelated to each other.
First, a command-line option allows `gawk' to recognize non-decimal
numbers in input data, not just in `awk' programs.  Next, two-way I/O,
discussed briefly in earlier parts of this Info file, is described in
full detail, along with the basics of TCP/IP networking and BSD portal
files.  Finally, `gawk' can "profile" an `awk' program, making it
possible to tune it for performance.

   Note: Adding New Built-in Functions to `gawk',
discusses the ability to dynamically add new built-in functions to
`gawk'.  As this feature is still immature and likely to change, its
description is relegated to an appendix.

Non-decimal Data

Allowing non-decimal input data.

Two-way I/O

Two-way communications with another process.

TCP/IP Networking

Using `gawk' for network programming.

Portal Files

Profiling
