1 This major node describes 'awk''s built-in functions, which fall into
1 three categories: numeric, string, and I/O. 'gawk' provides additional
1 groups of functions to work with values that represent time, do bit
1 manipulation, sort arrays, provide type information, and
1 internationalize and localize programs.
1 
1    Besides the built-in functions, 'awk' has provisions for writing new
1 functions that the rest of a program can use.  The second half of this
1 major node describes these "user-defined" functions.  Finally, we
1 explore indirect function calls, a 'gawk'-specific extension that lets
1 you determine at runtime what function is to be called.
