Write some Software

I'd like to update existing application. Please check attached source code so you understand what I'll talking about. Please enter random input and and get output file SO that you know the mechanism of the application. --In summary-- we will get N results based on the number of digits entered. If we put 5, it means 99999, if we put 4, it means 9999. and so on. and we will get Vcard file contains the results ( 100,000, 10,000, 1000, etc). In the updated version, I'd like the result to be divided in 2 Vcards ( in 2 parts) in order to make file smaller. Second thing, I want to be able to enter upto 15 Country codes. I will provide example to make things clear List name: EXAMPLE Country code A: +900 Country code B: +500 Country code C: +100 Number of digits: 5 ------ ( this will apply to all country codes) Suffix: 77 ----- ( this will apply to all country codes) After clicking start or enter or what ever I should get 6 Vcard files. ( we have 3 country codes X 2 files). Numbers will be named like 900A0000 900A0001 900B1234 500A0000 500B9999 and so on 1) File A: contains numbers +900 00000 77 TO + 900 49999 77 ( 50,000 numbers) File B: continas numbers +900 50000 77 TO +900 99999 77 (50,000 numbers) 2) File A: contains numbers +500 00000 77 TO + 500 49999 77 File B: continas numbers +500 50000 77 TO +500 99999 77 3) File A: contains numbers +100 00000 77 TO + 100 49999 77 File B: continas numbers +100 50000 77 TO +100 99999 77 You can review the output file attached.
