delphi的控制台语句是
write
和writeln
od反编译一下delphi生成的exe write('hello world');
0040820D ? BA 40824000 mov edx,Project2.00408240 ; hello world
00408212 ? E8 D9BCFFFF call Project2.00403EF0
00408217 ? E8 BCA7FFFF call Project2.004029D8 ;;以上两行输出字符串hello world.
下列四行代码存储 hello world 字符串。

以上是debug版，用release版本的结果是相同的，地址也相同，都是401028
