Re: How proprietary is the "COBOL file system"

My memory (without verifying this) is that they canNOT read each other's
proprietary systems. However, I think (but again am not positive) that
all of them have an option for using C-ISAM *instead* of their own
"native" systems. I don't know if this helps, but it might.


Thanks, Bill.

I think that's right. The problem is solved, (at least for this customer)
and I now have a tool set that can automatically migrate data and structure
from ISAM/ VSAM-KSDS to RDB, given the COBOL source definitions of the
Indexed files, without manual intervention.

I think most sites have converted to RDB long ago (it is quite a painful
manual process), but this will help with the ones who haven't... :-)

Can anyone tell me if MicroFocus COBOL can read Fujitsu ISAM files, and
vice versa? What about Realia?

Obviously, at the source code level (SELECT and FD/01) the code is
compatible, but what about object level?

Is there a single PC ISAM system, or do all the COBOL vendors have their
own proprietary indexed system which is delivered with their COBOL
compiler?

I know what I THINK the answer is, but would be gald to hear any other
facts/opinions about this.
