我开始学习汇编，并且正在使用《汇编语言艺术》一书。
我在尝试运行书中的示例时遇到问题。这是这里的程序：
program DemoVars;
#include( "stdlib.hhf" );
static
InitDemo: int32 := 5;
NotInitialized: int32;
begin DemoVars;
// Display the value of the pre-initialized variable
stdout.put( "InitDemo's value is ", InitDemo, n1 );
// Input an integer value from the user and display that value
stdout.put( "Enter an integer value: " );
stdin.get( NotInitialized );
stdout.put( "You entered: ", NotInitialized, n1 );
end DemoVars;
当我尝试编译它时，它在程序假设打印变量值的行中给出了四个错误，例如：
stdout.put: unknown data type
<n1 is type "">.
Near: << > >>
This output type is not supported.
Near: << > >>
有人可以帮我吗？
