Using getline into a Variable from a Pipe

When you use command | getline var, the output of command is sent through a pipe to getline and into the variable var. For example, the following program reads the current date and time into the variable current_time, using the date utility, and then prints it:

     "date" | getline current_time
     print "Report printed on " current_time

In this version of getline, none of the built-in variables are changed and the record is not split into fields.
