I'm almost certain you do not want to do what you asked. It's bizarre. Why not just write a normal program with a GUI or an inputdlg() to ask the user for some input? Or if it was something printed/echoed to the command window by a line of code in your program, just send that line directly to whatever other code needs it.

Well you could turn the "diary" function on to save all command window stuff to a file, then when you need to check it you could open the file and search for what you need to find.

Sometime there may be 100 millions of itterations. I need perform this action multiple times with multiple variables. That is why loop need to be stoped. If loop cannot be stoped, maybe turning diary off in certain point is an option?

You can turn it off and on at anytime with the diary command.

Open the diary file and search for the stopping condition with strfind() or endsWith(). If you find it, turn the diary off. Then since no diary will be continued I guess you'll have to determine somehow in your code when to start logging output to the diary again.
