But I need to read the nibbles and I can't figure out which ones to read. That, and I somehow created an infinite for loop.

What nibbles do you need to read?

If I understand what you're saying correctly, then you appear to have a slight misconception. First of all, let's go over number systems. Hex is basically a compact way of representing binary. Each hex digit is equivalent to 4 bits and so on. That means that each 8 bit long byte is composed of two hex digits, which you clearly understand. Now, a nibble is a four bits or half of a byte. When things are stored on the calculator, they're stored in bytes. This means that you have a series of hex digits like 01 23 45 67 89 AB CD EF in continuous addresses. When you extract a nibble from RAM, you're actually extracting an entire byte and simply masking it off. Because of how Axe addresses nibbles, to extract the second nibble of byte 3, you'd have to double the pointer to address 3 and add 1 (the first nibble would simply omit the addition). This addressing is probably where your problem is.

Also, just so you know, nibbles are slower and more difficult to work with. Their only advantage is that they take up less space.

Wait, I thought he was talking about Axe "lists", not the OS list arrays.

Er, butterflies. You *are* using butterflies to program, right?

I'm lost about what is the discussion about now.

To come back on-topic, did you have any luck Freyday with your program?

Well, I got it to recognize that the list M exists, but because the Axe only allows integers and the list contains nonintegers, I can't use the float{ command. That, and the last time I tried running the program, it produced absolute garbage (not the album, unfortunately; that would have been sweet) and was still going half an hour later.

Why can't you use float{?

I can't use float{ because the numbers have fractional parts and multiplying the list to remove the fparts would put the list elements over 2^16 (to the power, not modulo)

float{ gets only the significand (non-fractional part), no matter what power it's taken to (as long as it fits).

If you need the mantissa, you'll have to write your own routine Remember how FP numbers are stored.
