Hello.
This is not my proposal so far, but I haven't found any way to communicate with you. I want to clarify some things about the project:
1, The software will read input from the txt file, or from a text reader like BARETAIL?
2, "if number add number" - what does it mean?
If I can understand your requirement, I will give you how I can do the job. You won't be disappointment, I guarantee.
Thank you very much.
