 4.9.8 Using `getline' into a Variable from a Coprocess
 ------------------------------------------------------
 
 When you use `COMMAND |& getline VAR', the output from the coprocess
 COMMAND is sent through a two-way pipe to `getline' and into the
 variable VAR.
 
    In this version of `getline', none of the built-in variables are
 changed and the record is not split into fields.  The only variable
 changed is VAR.
 
    Coprocesses are an advanced feature. They are discussed here only
 because this is the minor node on `getline'.   Two-way I/O,
 where coprocesses are discussed in more detail.
