You import a PB DLL in Delphi3 just as you would import any other DLL. You start out by creating an import unit that tells Delphi what functions are provided by the DLL. Let's use a simple PowerBASIC DLL for an example:

$COMPILE DLL "AddOne.dll"
FUNCTION AddOne ALIAS "AddOne" (BYVAL x AS LONG) EXPORT AS LONG
   FUNCTION = x + 1
END FUNCTION

The source for your 32-bit Delphi unit will look something like this:

unit AddOne;

interface

   function AddOne (x: LongInt): LongInt; stdcall;

implementation

   function AddOne; external "AddOne.dll";

end.
