我代码：vara,b:integer;beginread(a,b);write(a+b);end.

编译失败...|错误号:1Free Pascal Compiler version 2.2.0 [2007/09/09] for i386 Copyright (c) 1993-2007 by Florian Klaempfl Target OS: Win32 for i386 Compiling MyProger\Prog91776.pas Prog91776.pas(1,4) Fatal: Syntax error, "identifier" expected but "ordinal const" found Fatal: Compilation aborted Error: Compiler\FPC\bin\i386-win32\ppc386.exe returned an error exitcode (normal if you did not specify a source file to be compiled) 

直接把答案复制进去：program Plus; var a,b:longint; begin readln(a,b); writeln(a+b); end.
