TStringLong Class Reference

ATTENTION: this class is obsolete.

It's functionality has been taken over by TString.

The long string class (unlimited number of chars in I/O).

This class redefines only the I/O member functions of TString. It uses 4 bytes to store the string length (1 byte only for TString).
