Bob,
Your first step is to convert your 6.5 DOS Forms and
Reports to 6.5++Windows. Then bring it into 7.5.
Remember DOS is text based, Windows Object based. You will
have a lot of work getting the Windows forms to look
respectable.
Same for reports. You would be well advised to go over each
form and report with your client to determine which ones are still
applicable
in order to save time.
As you
know, there are so many tools in 7.5 that were unavailable in 6.5 DOS. These
improvements totally change your approach to writing an app in 7.5 as opposed to
6.5 DOS.
I guess you have to consider if it is
less costly to your client to write the app from scratch, rather than
trying to re-write the DOS app.
Also, be prepared to replace almost all coding, as
feature and command changes improving efficiency is quite advanced in 7.5 from
DOS 6.5.
I am sure that you will want to use views, temporary
views and temporary tables to reduce the number of tables in DOS
6.5
in order to keep DB size at it's maximum efficiency.
Primary and foreign keys should be built into the
design.
Hope this helps.

Bill Eyring

Subject: [RBG7-L] - Conversion from Dos 6.5 to Windows 7.5
To be truthful, I have not worked with any Dos version
for a number of years. I have a prospective new client
that has a DOS 6.5 app that they want converted to
7.5. I would ask in general, is the conversion fairly
painless, or is there a lot of code deciphering that must be
done?
This is using the assumption that step 1 will to be convert
the app pretty much as is and then step 2, make mods and
improvements once they are up and going. I know that
some fundamental menu handling changes will be made early
on, but mostly the reports etc. will remain the same.
It has 11 application modules, 32 forms, 89 tables and
590 reports(believe it or not!) Most of these reports where
generated by thier in house users and I suspect a large number
may be obsolete.
This system was written over a long period of time by a former
employee of the client who is no longer with them. They like the
system and most certainly do not want to convert to any canned
package, however they want to move to a Windows based version
for future longevity, etc.
Again, what experience should I expect with DOS 6.5 to Win. 7.5
as far as Report, Application and Form conversions?
Thanks,
-Bob
