A way to set a position in a string

I'm working on a calculator for long strings and i have to add the strings backwards and then loop through and reverse the string into another string.
a reverse string function would be nice also.
and a qbasic like mid$(string,position) = character or string would be nice.

If only in need of replacing portions of a string and not increasing or decreasing the length of a string, then the advance function CopyMemoryString() can be used.
Thanks i guess??????

I already got the mul procedure working
i just added the strings right to left and then reversed the string.
its not pretty code but on a 2GHz dual core it blazes.
I posted the mul procedure here on the boards somewhere.
its two topics above the tailbite forum.

Nice start
You may want to have a look at a thread called "Huge #'s" where some people also tried to write fast routines which handle huge numbers...
