1. BCD-lib

Over the last few days i've been doing a bit of bcd-ing (simple things like
+,-,/,*,^ and sqrt). the routines i wrote seem to run at an acceptable speed (EG
adding 100,000 42-digit number`strings` takes less than a second). if some of you
are interested in it, i will `do a lib` of what i have so far and post it before
the end of this month to Rob. for the time being the routines take either a
sequence of atoms & integers OR a sequence of sprintf()ed atoms & ints. if you
all can live with this limitation let me know through the forum and i'll do the
job. we're talking full decimal calculations and not like most
BCD-implementations i found (like ABC) long integer-calculations.

A BCD library would dbe very useful.

My understanding from Electronics and its been a long time 10+ years since I
went to school but BCD is a four (4) byte representation of each decimal digit.
If this is the case, then how would it be usefull other than require massive
amounts
of Ram to store even the smallest string???
