That would have been a 360/370 IBM Mini. The 3270 was the "smart" terminal.

Yes, I use database libraries all the time with C/C++. Given Gnu COBOL 
had utilized the Berkley DB so they could provide full (or at least 
nearly complete) language syntax I had hoped Gnu Fortran did the same.

C/C++ never provided any indexed file or "record" level support. FORTRAN 
always did, so I had hopes.

Thanks,

Roland
