Terminal control/Restricted width positional input/No wrapping

Create a routine to obtain data entry using a specific place on the terminal screen. Data entry fields should be restricted to a specific length, and it should not be possible for the cursor to move beyond the input length.

Terminal control/Restricted width positional input/No wrapping is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

The routine should accept parameters for row number, column number and input length, and should obtain a string value entered by the user.

For the purpose of this task, obtain input from the user, showing data entry at row 3, column 5, with input width restricted to a maximum of 8 characters.

Note: In this task input wrapping is not allowed. (See Terminal Control/Restrict width positional input/With wrapping) for input wrapping variant
