RB strings are not mutable...
When you call " s = s + str(i) " a new string is created in
memory, the value of the old string plus the new string are added
together an placed in the new string, and then the old string is
taken out of memory.
Each iteration of this loop will therefore be a little longer than
the last, as the string slowly winds it's way up to 50,000
characters long.
Array's are much faster than strings for appends, but I defy you
to do an instr or countfields operation on one of your fast
strings....

Very true.
A MemoryBlock backed fast string could be mutable, fast and searchable
I think Charles has such a thing in http://declaresub.com/Code/
StringBuffer.sit
But I wouldn't recommend it any more; appending to an array + Join
is faster.
