We only have the EXE file, no source code, of the program created in Delphi 6. Amounts are being calculated using a hard coded constant (The discount rate) which links to another hard coded constant (The commission rate), we need the hard coded constant that is linked (The comission rate) to be edited.
As can be seen in the attached images when 0 % discount is selected by the user then the commission rate is 12 % and when the user selects a 5 % discount the commission rate is 11 %.
The following structure is in place and needs to be adjusted as follows:
Discount Old Comm rate New Comm rate
0% 12 % 16 %
5% 11 % 14.66%
10% 10 % 13.33 %
15% 9 % 12 %
20% 8 % 10.66 %
25% 7 % 9.33 %
30% 6 % 8 %
Do you have an idea on how to reverse engineer a software? it is impossible. do you accept rewriting the software from zero?
