Pascal to PB

[Gustavo Asplanatti]

Could somebody help me to translate to power basic this code portion written in pascal?
It would be of great help for my, thank you.

{$IFDEF NewInt08}
{$F+}
var
  LI          : Longint;

CONST
  Inside      : Boolean = False;
  ClockInt    : BYTE = $08;
  Smooth      : Boolean = True;

procedure NewTimer(Flags, CS, IP, AX, BX, CX, DX, SI, DI, DS, ES, BP: WORD);
interrupt;
begin
  IF Inside = True THEN
  begin
    IF Smooth THEN
    ASM
      pushf
      CALL OldTimer;
      sti
    END;
    ASM iret end;
  END;
  Inside := True;
  Driver_IO;
  ASM
    pushf
    CALL OldTimer;
    sti
  END;
  Inside := False;
END;

procedure NewExitProc; far;
var
  SaveExitProc: POINTER;
begin
 { ExitProc := @SaveExitProc;}
  SetIntVec(ClockInt, @OldTimer);
  SaveExitProc:=ExitProc;
END;
{$F-}
{$ENDIF}

begin
  IF Driver_Init THEN
  begin
   {$IFDEF NewInt08}
    SaveExitProc := ExitProc;
    ExitProc := @NewExitProc;
    GetIntVec(ClockInt, @OldTimer);
    SetIntVec(ClockInt, ADDR(NewTimer));
   {$ENDIF}
  END;
end.

I am consumed with the desire to say the whole thing converts to:

POPUP TIMER

(If this is a piece of an MS-DOS TSR program, I know this is correct).

Yes, POPUP TIMER or POPUP INTERRUPT might be the right answer. It
looks like this code needs to run on every tick, though, so the overhead
may turn out to be excessive. If that proves to be the case, the interrupt
handler will need to be written entirely in inline assembly language.

Try POPUP TIMER first.

The code modifies the time interruption DOS so that
TRUMPET (Copyright 1992 by Peter R. Tattam) can manage
the packages sent by my code regularly.
I have already solved it, adding the capacity to manage
UDP in the librery of Gerhard Zugarek TCPABI.INC, totally
written in assembler.
Of the other side receipt the packages sent under a program
in Windows with PB Win 7.02.

I thank your help and to be sincere I had also planned to
use POPUP TIMER it was a simpler way to solve this.
