According to my Model III Basic manual, the # sign
indicates that you are dealing with double precision
variable.  I assume the same is true for a Model I.

The manual says "Double-precision numbers can include
up to 17 significant digits.... A double precision
value requires 8 bytes of memory for storage.
Arithmetic operations involving at least one double-
precision number are slower than the same opeations
when all operands are single-precision or integer."

Hope this helps.  -- Ernest
