curses suggestions wanted_(re)

Hi all,

I have come across a problem (bug? feature?) trying to pass a string schema
parameter to a procedure with a parameter defined as a __cstring__.  Please
note that I am still using ver 2.0 so if this is fixed in the newer version,
let me know.  Here is the problem:

This program works:
8<--------------------------------------------------
program works1;
(* GPC 2.0 *)

procedure foo(abar : __cstring__);
begin
   (* dummy proc *)
end;

var
   blab : string (200);
begin
   blab := 'Test Me';
   foo(blab);
end.
8<--------------------------------------------

However, the following program does not.  I get the following error when
trying to compile:
dwork1.pas: In function 'program_Dwork1':
dwork1.pas:16:incompatible type for argument 1 of 'Foo'
8<---------------------------------------------
program dwork1;
(* GPC 2.0 *)

type
   aCString =  __cstring__;

procedure foo(abar : aCString);
begin
   (* dummy proc *)
end;

var
   blab : string (200);
begin
   blab := 'Test Me';
   foo(blab);
end.
8<------------------------------------------

Also, if I define a proc in a unit like:

procedure foofoo(acstr : __cstring__);

and call it from a different program like:

foofoo(SomeStrSchema);

I get the same error as above DWORK1.PAS  program.
*******************************************************
Regarding the Pascal -vs- C calling, I like your suggestion, Peter.  I would
much rather have the string variant be the default but provive the bare
ncurses calls just in case.  However, the naming may need to be like: pfoo()
and cfoo().  The way I understand linking to a C rtn like:

function cfoo(SomeNum : integer) : integer; C;

requires that I link a C library that contains a function called `cfoo'.  If
I could specify a different C fcn name to link to ( I think this was
discussed before) I could call the procedures almost anything!

Thanks much!!!
