Description of Strings Unit :
Delphi 1.0/Delphi 2.0 string compatibility unit. Delphi 2.0 has long strings, and uses the SetLength and SetString functions to manipulate them. Delphi 1.0 lacks these functions. For portability, this unit defines these procedures appropriately for Delphi1.0. Also, Delphi 2.0 has implicity conversion from string to PChar, so define AsPChar which uses the implicit conversion in Delphi 2.0 and does an explicit conversion in Delphi 1.0.
