    What do you mean with "create a document"? What document format are you talking about?

    Bye, Andreas

    Your console can print in several colors, AND in "blinking" mode (what you call flashing).

    It's not part of C, but you can do it in C, using either a non-standard header (conio.h), or ncurses, or if you are in Windows, you call do it using the windows.h header.

    Does your compiler support conio.h, or do you have ncurses, or use Windows?

    You can make text flash also, simply by printing it, then overwriting it so it disappears, and then printing it in the same position again. That can be done using standard C.

    For an alert however, a nice red or yellow color would be nice, wouldn't it?

    So:

    conio.h
    ncurses
    or
    windows.h

    are your best choices.

    Check it to be sure it supports conio.h:

    Code:
    #include <stdio.h>
    #include <conio.h>
    
    
    int main(void) {
       gotoxy(10,10);
       printf("OK\n");
       return 0;
    }
    copy paste, and compile that. When you run it, if it moves the cursor to line 10, column 10 then you have conio.h. If it gives you an error and won't compile, then you don't have it.

    You need to change gotoxy() to _gotoxy(), if you are using Pelles C on Windows.

    it says that gotoxy() / _gotoxy() is undeclared

    It sounds like curses would be best suited for this task. Install either ncurses or PDcurses as they both work in Windows. Then you need to take it step by step by writing a message in a specific color in a specific spot on the terminal, then introducing a delay, then writing it again in a different color, etc... there is no built-in function to flash text in different colors, you have to implement this yourself.

    Sounds to me like you want to produce an html doc with the equivalent* of the dropped 'blink' tag.

    * By equivalent, I mean one can use javascript to the same effect.
