Not /my/ code, Christopher.  Well maybe some, I adapted it to work on 
both processors, but its been around for quite a while, before nitros9 
by several years...  Used it heavily while I was writing vfy because I 
wanted to make it so bulletproof it could work on a file in-situ. I 
succeeded quite well I think. Make a  mistake, any mistake, and it 
doesn't touch the file, but does spit out its help screen.  It's only 
gotcha is its memory size needed in the file header, the math is 2's 
complement, so to reduce the memory, use a figure above 32k, so it 
overflows the 16 bits, throws the carry away. and writes the remainder 
in the files header.  Its not a feature most use anyway, but I got tired 
of launching all the "ts-edit git" with a #56 so it would ask for 56k of 
buffer and made it permanent.  Makes life a wee bit simpler.

How was the show? Few have said so far.
