This isn't much of a [[tutorial]], rather some example code, but anyway. This code shows that text input in [[Fenix]] is not hard at all: with just a little piece of code, much can be achieved. Note that this is code for Fenix versions [[0.93]] and up.

== Example code ==
<pre>
Program texts;

Declare Function String textinput();
End

Begin

set_fps(60,0);

say("You typed: '" + textinput() + "'");

Repeat
frame;
Until(key(_esc));

End

Function String textinput()
Private
String str;
int t;
int t2;
byte last_ascii;
int txtid;
Begin

// show what you type in top left corner
txtid = write_string(0,0,0,0,&str);

// clean the string
str = "";

// get input from the user
// pressing enter will end the loop
Loop
if(ascii!=0&&last_ascii==ascii) // check if a key is pressed and if the same key was pressed last frame
if(t==0||t>fps/4) // check if the key was just pressed or it has been pressed for 0.25 seconds
if(t==0||t2>fps/30) // check if the key was just pressed or it has been pressed for the last 0.03 seconds
t2=0;
switch(ascii) // handle input
case 8: //backspace
str = substr(str,0,len(str)-1);
end
case 13: //enter
break;
end
default: //addkey
str+=chr(ascii);
end
end
end
t2++;
end
t++;
else
t = t2 = 0; // reset
end
last_ascii = ascii;
frame;
End

// delete the text used
delete_text(txtid);

// return the typed string
return str;

End
</pre>
Used in example: [[set_fps]](), [[say]](), [[write_string]](), [[substr]](), [[chr]](), [[declare]], [[function]], [[switch]], [[ascii]], [[fps]]

You'll find a nice ASCII table [http://www.asciitable.com here].
