    Thanks for replying, Eli. The piece of code where kbhit() is being used is a
short function, as shown below:

void check_event(int *key)
{
    while (kbhit()) getch();
    *key = bioskey(0);
}

    Called at this program segment:

        [...]
        check_event(&cmd);
        p = toupper(cmd);
        if (p == 'R')
            return;
        if (p == 'A') {
            build_amort(v);
            display_amort();
            factor_header();
            aflg = 0;
            fflg = 1;
            return;
        }
        [...]

    It should then (in theory) capture a keyboard hit, make it uppercase
    and then decide what to do with the result.

    Now giving the code a closer look, it is quite possible that the error
    is due to the function bioskey(). Maybe.

    Thanks for any help.
