Nematron IWS FI_ viewing

Hi
I have some old Nematron 3025 terminals with much product spec data held in binary files. I have tried to open using VB but with no luck.
The files have extension FI_ and Nematron refer to them as Binary. The normal screen files and basic program are Ascii. I would be grateful is someone has done this before or can give me a clue.
I know the file has 100 records which are 40 chars long.

Thanks, Chris

Further to above, I was wondering if i had a file system issue so maybe i cant open these files at all.. just a thought. The terminals are programmed using Nematrons 'Optibasic' i this rings any bells.
If someone is willing to try a file, i can attach one, they are only very small in size.

OK, chreers again, Chris
