| I have a application that generates and tracks sales orders and billing.
This has about 100,000 records, about 100 programs (.prg files) and numerous forms and reports.
I wish to update to a newer windows based version of Dbase. could someone recomend ;
1. Which version would be best.
2. Will my old code work.
3. How steep is the learning curve for a new language.

Ron:
dBase Plus is current flavor with 2.6 the most recent release. I myself made the jump from dBase III just one year ago. I too had a significant investment in data and code. My rewrite took about 12 weeks (8 of which were getting a handle on the new
methodology).
Most of my code value was also in the processing, not the user interface. This can be your saving grace as dBase Plus can virtually run the old xbase code without modification. The learning curve falls therefore squarely in two areas. 1., the new c
ontrols and operations of them in conjunction with your old code, and 2., the knowledge and desire to 'upgrade' old internal workings to more efficient constructs such as sql queries and joins over 'use' and 'set relation to', and resulting rowset data
model.
My upgrade process continued to rely on my old operating code while I developed using dBase Plus as an upgraded data "viewer" - adding interfaces through time as they were developed. This provided a transparent transition for users and data continuity
without the pressures of a hard transition.
All in all, it's a superb product, and once you get the hang of it, a far faster development platform that early versions and alternate products.

Thanks for the advise. This sounds like what I should try.
One other question I have is, will the version you recomend work with the new version of windows due out at the end of 2006.

There is no reason why not.
MS has a vested interest in ensuring that applications run.
dBI has a vested interest in ensuring its products run.
More likely that new OS "security" settings may require tweaking.
More likely 2007 than 2006 <g>.
