Question: About Dayz Scripts

Hello I got 2 Questions.
1.
Is it possible to write a Script, that reads what u writes and display it on someones screen? Like the lock feature but
you can choose the text by yourself without editting the sqf file.

2.
Is it possible to create a variable in sqf files. Its basically the same question as above. Read what the User writes, then display it.

1. Yes that it possible
2. No Its Not I Believe

I do believe Rustler's menu V3 has the script you are looking for, for number 1 that is. As for number 2 I'm not nearly experienced enough to tell you that.

1) This would need to be external But yes it is possible
2) as a variable you mean something public? so you can use it in multiple scripts? yes but there are a lot of limitations
Ex. If you create a variable of _pos = player getpos then you would need to use an executioner to bring that over so something on the lines of
[_pos] execVM "Scripts\cheats\VariableExec"
and then you would need to run another Executioner to pull the _pos from the executioner
seems possible but extreamly hard
