 Explicit Input with `getline'
 =============================
 
    So far we have been getting our input data from `awk''s main input
 stream--either the standard input (usually your terminal, sometimes the
 output from another program) or from the files specified on the command
 line.  The `awk' language has a special built-in command called
 `getline' that can be used to read input under your explicit control.
