I have a task for programmers (those who are not yet in the course of this task).

Write an MQL script that outputs its source code to a file.

You cannot read from the file.

It is possible not the script itself, but the approach to writing it.

MQL4: Sharing file between Importing live data from Machine learning in trading:

I heard about one when I was still learning. The language has to be quite powerful to do that. I doubt it will work for MQL4.

on mql is unrealistic, there is no memory work.

на mql нереально, нет работы с памятью.

I think MQL is enough.

"The problem can be solved in any programming language that has the ability to output an arbitrary computable string of text."

I don't know about MQL, but in VB the solution is this:
Generate a CTRL+PRINTSCR keystroke capturing a screenshot to clipboard. Save the clipboard as a file.

Oh, right, I forgot about CharToStr().
Voila, the quine in MQL. Please test it :)))

int start(){string s="int start(){string s=;Print(StringSubstr(s,0,21),CharToStr(34),s,CharToStr(34),StringSubstr(s,21));return(0);}";Print(StringSubstr(s,0,21),CharToStr(34),s,CharToStr(34),StringSubstr(s,21));return(0);}
