    Post Interactive line editing

    Hi Guys,

    I am currently trying to write a console based util which needs users to interactively edit a line of text.

    I want to output a line to the text console and then allow the user to edit the line I have just written - similar to the behaviour of a text editor when you save a file - it presents you with the current filename of your file and allows you to edit it. Only one line of text at a time needs to be edited - I am not trying to implement a text editor.

    Please help!

    you want to print 1 line of text, and to let the user edit it.
    Well, this means that you know:
    1. how long is this line
    2. the position on the screen where you will print it
    3. The User can make only this:
    1. To move only left/right
    2. To insert a "char" in the string
    3. To delete a "char"
    4. (optionally) to have End/Home

    So, read the mans about manipulating the cursor on the console text screen.
    Then, just read the KBD and filter the input. If the allmighty User hits the DEL button or arrow and etc - now you know what ti do :)))

    Mr.PLS.... Enjoy coding
