Hi,

I'm converting a project from Sibyl (a old OS/2 IDE implement in SpeedSoft Pascal).

Below is the code I'm trying to convert to Free Pascal. I see FPC has a PString type, but not FreePString() or NewPString(). Searching the FPC source code, I found the FP Text IDE using PString all over. The FP Text IDE uses this... <some PString var> := NewStr(<string>);

Do I need this when I use String = AnsiString in my projects?  Or can I
simply do the following assignment:  _Title := @NevValue;
---------------------------------
_Title: PString;

...

procedure TTopic.SetTitle( const NewValue: string );
begin
  FreePString( _Title );
  _Title:= NewPString( NewValue );
end;
---------------------------------

Sorry if this sounds dumb, but I have never used PString before.

Regards,
- Graeme -

No worries, I solved my problem by using AnsiString across the board.

Regards,

If you want to ansistringify, assume that pstring as a whole is ansistring, and remove all pointers and let ansistrings automatic maintenance work.

Be careful with newstr, there are multiple versions of it. (a TP and Delphi version) see

Don't ever include objects and sysutils in the same unit.

Thanks Marco. That's what I did. I read bit more about PString and it seems pretty safe for me to simply replace it with AnsiString. So far so good.

Good to know. I'm converting all Objects types to Class types too.
