The Nibbler cruncher

I have tested your cruncher with a few reasonable large files and there was no case where it beat CrunchMania, here are my stats:

ASM-One (288464 bytes) Nibbler: 151336 CrM: 140280
Asm-Pro (206692 bytes) Nibbler: 110064 CrM: 104288
CrM (42108 bytes) Nibbler: 24238 CrM: 23524
FLM (127620 bytes) Nibbler: 58534 CrM: 52160
SysSpeed (150676 bytes) Nibbler: 75968 CrM: 57276

Also, it seemed to be very slow and seemingly doing nothing (as there was no process indicator at all), this should be changed so that it is possible to know what's going on, when I first tried it I actually thought it crashed and used a debugger to check what was happening. Other than that it looks promising already, I like that it is is simple CLI executable, very handy!

Did one test against StoneCracker'ish that never saw a daylight:
Asm-Pro (211932) 101616 bytes

Sorry, I could not resist

Hours to compress on a 040? Can't be right. Let me check.

Confirmed, there's something seriously wrong with the Nibble command. Didn't plan on touching the cruncher this weekend but I'll have a look. I can see how you think this is slow should be hundreds of times faster than this at least...

If you need me to supply the DD_AllSquare file I can. Any ideas as to what could be causing it to compress so slowly?

Just a slight correction. I have done compression work before... about 9 years ago I did look into RLE and LZW compression (in AMOS Basic), as a learning point for compression. I never got around to creating any of my own compression routines though.
