Terminal control/Restricted width positional input/With 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 the cursor should not move beyond the input length.
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 allowed. If the length of input exceeds the maximum width, the left hand side of the field should disappear, allowing additional input to be obtained. However, the cursor must not move beyond the designated input length.
It is permissible to use navigation keys to see input field length.
