Amywhere from easy to impossible, depending on whether one has a full
spec of the virtual machine that allows you to identify what a 'call'
is and where the parameters are and what they mean. Do you have the
full spec of the RM virtual machine ? I thought not.

They probably bought it when it was a reasonable company (ie actually
SCO and not Caldera who are the one that called themselves SCO and
then abused the legal system).

I don't care about _that_, they get told to bugger off, too.

I don't know where you got that, they have support but no volume as
3.65 at the moment. 1.45 is probably more realistic, especially when
they have set themselves up able to move their cash reserves to the
Canopy group.

OpenServer can keep running even if SCO folds, it's not like the
licences will expire. As it is trivial to move the system over to
Linux (but will require RM licences) it is only an issue of money.

On SCO Unix ? For free ?

Another bit that you missed ?

The 'file maintenace' that you said you could do in 'one program' was
for RM Cobol data files which are _not_ C-ISAM. The file convertion
which was my example of templated generating which you also said you
could do was Fujitsu.

Good deflection. Just write it in a _portable_ way that doesn't
require any dependancies. That's the solution that I suggested.

How ironic that you say that. I suggest a solution that can be done
in a portable way with no dependancies and your comment was:
"""How ugly."""
"""Rubbish."""
"""Automated cut-and-paste programming at its worst."""
Your suggestions have been non-viable (such as byte reading RM ISAM
files) or cost money (such as Excel, Windows, ODBC drivers, replacing
SCO, TOAD, File-Aid).
Now you attempt to reverse this.

Did I use '2 different copybooks' for FDs ? I think not. But then
you do seem to miss much in the messages. No, I didn't show how the
data was copied, it was a small sample to show how the templating was
done.

While you don't even seem to read what they do say, you missed 'RM
Cobol', 'SCO Unix', 'adding records'. No wonder you think they never
seem to tell you what they want you simply fail to notice. It is also
no wonder that they keep telling you that you are 'cold', you just go
off and do something 'interesting' rather than anything relevant.

It is an application programmer's solution to an application

I suggested Cobol programs, which particular one is 'inappropriate' ?
> People accuse me of using the wrong tool;
Yes they do. So far you have suggested MF specific and C-ISAM specific
tools such as EXTFH and byte accessing ISAM files which fail on RM,
Windows specific tools such as Excel and ODBC flat file drivers that
won't run on SCO Unix. Producing CSV files, putting the file in an
SQL database, File-Aid for DB2, all of which completely miss the
point.
