I dont know the file structure and type default of a application file.
The software house dont wont give me more info. I want convert data csv.
Is there a tips for understant it.
I think acucobol format, butn i am not sure.
Unfortunately I know nothing about AcuCobol (other than its Indexed files use a propriatry format). So I can not help you.
I suspect you may need a commercial product, some of them claim to be able to read Acu Cobol files (eg acuODBC)
