Delphi 3 introduced the possiblity to easily place constant strings as
a resource with the new keyword 'resourcestring'.
If you want to write code that compiles both with Delphi 2 and 3 because you
are publishing a component, take a look at this sample code:
// this is code for Delphi 1/ 2.
// It uses LoadStr to access resource strings
raise SomeException.Create(LoadStr(SInsertLineError));
// this uses VER100 to detect if Delphi 3.x is used.
raise SomeException.Create(
{$IFNDEF VER100}LoadStr{$ENDIF}
(SInsertLineError));
