Can you show me The "Hello World" in MT4

[Ma Yuliang]

I am a fresh man for mql4 language.

The start always be very hard for a new man.

Could any one tell me how to output a "hello world " in the log?

That is important to me , to learn a new code I need check the right or wrong of a var.

I can't check it if I can't output it.

I tried Print() but it's not work.
