To interface ncurses from Lisp, the ''[https://www.cliki.net/croatoan croatoan]'' library is used.

This uses _getch() rather than _getwch() as only ASCII is supported.

=={{header|Julia}}==
Requires an ANSI compatible terminal and a system C library implementing _getch() for unbuffered keyboard input. Note the code below is identical to the code in [[Terminal_control/Restricted_width_positional_input/No_wrapping]] but with no width argument in the input call.
<langsyntaxhighlight lang="julia">getch() = UInt8(ccall(:_getch, Cint, ()))
cls() = print("\33[2J")
reposition(row, col) = print("\u001b[$row;$(col)H")
Line 155:
s = input_y_x_upto(3, 5, 8)
println("\n\n\nResult: You entered <<$s>>")
</syntaxhighlight>
</lang>
 
=={{header|Kotlin}}==
Line 164:
 
It would also be possible to allow for printable Unicode characters (>= 160) to be entered by adding an extra clause to the 'when' statement. However, for this to work properly, you will need to be using a suitable code page (65001, say) and a suitable font (Lucida Console, say).

=={{header|Nim}}==
Line 211:
As in the Julia version we translated, the code is identical to the code in [[Terminal_control/Restricted_width_positional_input/No_wrapping]] but with no width argument in the input call. See this version for some general comments about the code.
