1 1.7 Other Features of 'awk'
1 ===========================
1 
1 The 'awk' language provides a number of predefined, or "built-in",
1 variables that your programs can use to get information from 'awk'.
1 There are other variables your program can set as well to control how
1 'awk' processes your data.
1 
1    In addition, 'awk' provides a number of built-in functions for doing
1 common computational and string-related operations.  'gawk' provides
1 built-in functions for working with timestamps, performing bit
1 manipulation, for runtime string translation (internationalization),
1 determining the type of a variable, and array sorting.

1    As we develop our presentation of the 'awk' language, we will
1 introduce most of the variables and many of the functions.  They are
