1 5.11 Summary
1 ============
1 
1    * The 'print' statement prints comma-separated expressions.  Each
1      expression is separated by the value of 'OFS' and terminated by the
1      value of 'ORS'.  'OFMT' provides the conversion format for numeric
1      values for the 'print' statement.
1 
1    * The 'printf' statement provides finer-grained control over output,
1      with format-control letters for different data types and various
1      flags that modify the behavior of the format-control letters.
1 
1    * Output from both 'print' and 'printf' may be redirected to files,
1      pipes, and coprocesses.
1 
1    * 'gawk' provides special file names for access to standard input,
1      output, and error, and for network communications.
1 
1    * Use 'close()' to close open file, pipe, and coprocess redirections.
1      For coprocesses, it is possible to close only one direction of the
1      communications.
1 
1    * Normally errors with 'print' or 'printf' are fatal.  'gawk' lets
1      you make output errors be nonfatal either for all files or on a
1      per-file basis.  You must then check for errors after every
1      relevant output statement.
