Re: tables problem

["D Burgess" <db@...>]

May or may not be your problem but,
from the manual -

All three control expressions are evaluated only once,
before the loop starts.

Note the once.

After the first table.remove, the second parameter of
the 'for' will be a number larger than the number of 
table entries.
