[rkv19]

Hi ,
I am using a software written in Visual Basic and simulation of which is written in Fortran . In this software in interface when i open a cateogory and give one set of values to parameters and run the S/W then i get results. My problem is i want to enter 100 such set of parameters one by one reading from a text file each line containing 1 set of parameters needed for one execution . I dont have the source of the software written , Can someone help me with some other way externally if i can do that ??and if yes.. please tell me how i can do that !!!

Thanks a lot

OK I'm thoroughly confused. What language are you working with? VB, Fortran or C++?

sorry for confusing .. I am working with C++ . I need code to read line by line from a text file and modify a particular line in a main file & create as many main files as no of lines in the text file . then run a software over each modified file .

What does the "main" file look like?
