Thomas,
most likely born after they came out with the 3.5" "Floppies" I still have a box of double sided double density still in the shrink wrap. Just 'cus.

I made a lot of money in the mid 80's transferring data from Radio Shack Model II 8" floppies to IBM PC 5 1/4" with Pickle & Trout CPM and TRIS-DOS on the Model II and a Heathkit Model 100 running MS-DOS. The Pickle & Trout CPM could read the TRIS-DOS floppies and transfer the data to CPM. The Heathkit had 5" internal drives and I had an external 8" box and could copy between CPM and MS-DOS. Even did a conversion from CPM to MS-DOS for Johns Hopkins University.

I ran the calibration and metrology labs for Ampex Corporation and we controlled over 30,000 pieces of measurement and electronics test equipment. It took six months of spare time to write the program, and each time Ashton Tate came out with a new product it took a rewrite. Finally, I went to Fox, and gave up on Ashton Tate.

>>I believe you are confusing dBASE II with dBASE III. Big difference. dBASE II had no memo fields. However, I do believe that VFP should be able to read them and it looks like someone did something with these files that trashed the headers. So... Off I go with low level file reading.

>>>VFP will read these files without any problems. If memo fields are involved, VFP will convert them, I seem to remember that it's the same for mdx files (dBase version of cdx index files) . In other words, most likely you won't be able to use the files from dBase afterwards.

>>>>Hi folks,
>>>>I can't believe someone just gave me a set of dBASE II tables. I don't have anything that will read them anymore. Can anyone point me to something that will? Even if I can just export to text would be a start. I know I could write a prg using fopen and fread and decipher the headers then read them but that would take more time than the job is paying.
