delphi – 如何修复程序循环引用？

我的简单应用程序是通过Windows上的telnet服务器运行的项目库存.
我使用旧的thinkpad作为我的瘦客户端运行linux和telnet客户端.

使用Delphi XE我遇到了鸡肉或鸡蛋的情况.

我得到了addscreen未声明的标识符…它被声明但是在主屏幕下！
如果我把addscreen程序放在主屏幕上,那么在addscreen程序中对mainscreen的任何调用都会让我误认为是unclared标识主屏幕！

简单来说,如何让程序在程序中到处调用？

我已经尝试过接口和实现,但它在控制台应用程序中无效！

program Project1;

{$APPTYPE CONSOLE}

uses
  SysUtils,windows,messages,Console in 'Console.pas';


procedure mainscreen;
var
  choice: String;
begin
  clrscr;
  writeln(' ------------------------------------------------------------------------------------------------------------------------------');
  writeln(' |                                     Inventory Management 0.1 ALPHA                                                         |');
  writeln(' ------------------------------------------------------------------------------------------------------------------------------');
  writeln('');
  writeln('');
  writeln('');
  writeln('');
  writeln('');
  writeln(' Make a choice: Add(a),Remove(r),Edit(E),BACkup Database(bd),Mass Add(ma),Mass Remove(mr)');
  writeln('?:');
  readln(choicE);

  if choice = 'a' then 
    addscreen
  else 
    mainscreen;
end;

procedure addscreen;
var
  choice: String;
begin
  clrscr;
  writeln(' ------------------------------------------------------------------------------------------------------------------------------');
  writeln(' |                                                     Add an Item                                                            |');
  writeln(' ------------------------------------------------------------------------------------------------------------------------------');
  writeln('');
  writeln('');
  writeln('');
  writeln(' Not yet ready!');
  writeln(' Press any key to return to the main menu...');
  readln(choicE);

  mainscreen;
end;

begin
  mainscreen;
  textBACkground(black);
  textcolor(lightgray);
  ExitProcess(0);
end.

非常感谢你！
