i have some differnt validity .dat files. i have to make the validity files from my UI page. but the thing is that there are some parameters which are having different value format.the logic of the .dat file is different from each other. so can i set catogeries the parameter which is having parameters value and reading that layout new validity .dat is created via UI screen which shoud follow the same logic for that file. means i have to make a copy of the file with same format but different value using INI file.
