// myLine.h
//
// Donated to the public domain; no restrictions on reuse or abuse apply.
// by David Nugent, 7th June, 1993.
// Simple line input class for istream to demonstrate input of a complete
// line rather than whitespace separated tokens (the default for operator<<
// for char* and other built-in types).
// Works by overloading operator>> for a customised class - this functionality
// is easily incorporated into your favourite String class
//
# if !defined(_myLine_h)
# define _myLine_h 1
# define AUTO_GROW 1 // Allow autogrowth of buffer to fit
# define ALLOC_LEN 80 // Standard length & growth increment
// Class declaration
class myLine
{
public:
myLine (short buflen =ALLOC_LEN);

// Get buffer address
