[oopic] Re: Strings & Manipulation

Since you already have the information in the buffer, you need to
examine each digit and add them together with the correct multiplier.
You might have to get fancy to determine the number of digits. To get
the digit from ASCII to decimal, simply subtract 48 from the value and
there you go. Now start right to left and add the Right*(10^0) +
(Right-1)*10^1 + (Right-2)*(10^2)... Until you get to the left digit.
One possible method would be to find the space and then work backwards
from there adding the digit and the multiplier. If you need some help
with the code, let me know and I will try to help you.
