Hi Derek:
I moved the start time after the dir() command in your program, so as 
not to include that in the total. I didn't need to do a dir() in Lua, in 
order to read the entire file, and I haven't found Lua's equivalent yet, 
anyway.

Euphoria: Filesize=390768 Seconds=0.220000 in=0.110000 out=0.022000  
Lua: Seconds=0.050000 in=0.010000 out=0.008000
Subsequent runs of Lua are about 20% faster.
Subsequent runs of Eu are the same.

Regards,
Irv
