Following your conio.h advice Ullrich, I came up with
this bit of code for entering user data....

int usernumber(void) // get user input 0-9999
{
    char temp[1], get=0, store[4]; // temp char used to echo user input 
    int pickit;  // user value returned
    while (get<4)
        {
            store[get]=cgetc(); // get chars until "return" or 4 digits
            if(store[get]=='\n')
                get=4;
            if(isdigit(store[get]))
               {
                   *temp=store[get]; // temp store the digit
                    printf("%d", atoi(temp)); // "poke" it to the screen
                    get++;
                }
        }
    return((pickit=atoi(store)));
}

It takes in a string ignoring non-numerics, converts
then returns an int from 0-9999. It also echos the input
to the current cursor position so you see what your typing.
Working great so far, and I can modify it to enter any thing
I like. Thanks Uz and Marc for the help.
