This had me puzzled for a minute:
program CodeLibrarian; {$R *.res} uses GX_VerDepConst in '..\..\Framework\GX_VerDepConst.pas'; procedure ShowCodeLib; external GExpertsDll; begin ShowCodeLib; end.
This is all the code there is to the stand alone Code Librarian tool that comes with GExperts. Then it dawned me. It’s much easier to understand if you add a single line feed:
program CodeLibrarian; {$R *.res} uses GX_VerDepConst in '..\..\Framework\GX_VerDepConst.pas'; procedure ShowCodeLib; external GExpertsDll; begin ShowCodeLib; end.
The procedure ShowCodeLib is an external declaration that does not have a body. The begin / end are actually the main program that calls ShowCodeLib.
