If I use a fractional number for [COMB] the HP42 will give "INVALID DATA". Correct ofcourse. BUT if I do the calculation again with an integer number it will still give "INVALID DATA". I first have to make a random calculation [+] or [-] or whatever and after that [COMB] will work again. Clearing stack and last X will not help. In my program I put in an extra step to make sure it's an integer.
Are there more with this bug ?
