Query on Delphi 2007 and its compatibility.

[Ajith Nair]

Hi,

1.. I would like to know whether I can compile my existing Delphi 5 source
code (in Windows XP) in Delphi 2007 (in Windows Vista) without any changes
in source code.
2.. Whether compiled executable from Delphi 2007 (in Windows Vista) has
downward compatibility in Windows XP, Windows 2000, and Windows 98 etc?
3.. If I am sending a small module which is in Delphi 5 (in Windows XP),
is it possible to compile and send the executables back to me for to test in
Windows (Vista, XP, 2000 & 98) operating system?
Looking forward for your reply

Thanks in advance

Yours Sincerely,

Ajith Nair

Maybe. Some things have moved to different units so you may need to
change your uses clause.

The O/S the compiler runs on should have no effect on the EXE that the
compiler produces.

Download the D2007 trial and test as much as you like.

You will probably have to make some minor changes to your D5 source code
to get it to compile in D2007, but these changes date from D6, with the
addition of the Variants unit.
