Hi Gregg,
Short of puting the percent value in a string, how do you write a
dialect to get around the following? ...
>> [10%]
** Syntax Error: Invalid integer -- 10%
** Near: (line 1) [10%]

Perhaps because they're saving decimals for percentages and didn't
want a whole heap of scripts out there already using them in pairs
when it's introduced? ie, so it /won't/ open a can of worms when
it's introduced.
