Paradox Engine 2.0 under Turbo Pascal For Windows
_____________________________________________________________________________


The following documents the differences between the syntax for calling
Paradox 2.0 functions as found in the Paradox Engine Pascal Reference and
how they need to be called from Windows.

To compile and run the sample programs, add the following as your uses
statement:

uses PXEngine, WinCrt;

The function PX is not supported, but you can use the following in the
sample programs so that they compile and run:

procedure PX(Code : integer);
begin
writeln(PXErrMsg(Code));
and;

You Must use PXWinInit instead of PXInit:
PX(PXWinInit('MyApp', pxShared));

Data Type Changes:
NameString needs to be declared as type PChar,
The type TDate is Longint, and
FieldHandleArray = array[i..j] of FieldHandle;
variables of type boolean need to be changed to type Bool, and add
Uses WinTypes;

fuctions that have a string as a parameter type to a function now
need a parameter of type pChar. You can use an array[0..N] of char.
Then use the address of the array for the parameter.

In PXGetDefaults() and PXSetDefaults(), the var SortOrder is of type char
not pointer, and the SortOrder constants are as follows:

SortOrderAscii = 'a'; { ASCII sort order }
SortOrderInt = 'i'; { international sort order }
SortOrderNorDan = 'n'; { Norwegian/Danish sort order }
SortOrderSwedFin = 's'; { Swedish/Finnish sort order }

PXLoadOverlay function is not implemented in Windows (of Course!).
