COBOL - How to read and export text from .dat files

i got a customer who wants to migrate from an old Fujitsu COBOL based system to our system, said that, he wants his old data to be kept in the new system, like products,manufacters, etc.I dont have the COBOL source file, i have: .DAT files, .RDD files and .FDD files.

Apparently the .DAT files are in the INDEXED organization, a sample file output bellow:

FDD output:http://textuploader.com/kxdv
RDD output:http://textuploader.com/kxdw

I can't simple read the .DAT file in notepad, i've tried the SiberDataViewer but unsuccesfull, also it gets paid to export the data.

If there's a way, can i write a program to export all these files to csv,dbf,postgres format?
If you are still reading, thank you.

Solution

  • I could convert it using the Siber DataViewer, but, its full version is paid.
