I totally agree with you, Tom - I had a large 2.6 Fox app and converted it via basically a 'recompile' in 1999. It had the Windows 'look-and-feel' but that was it - the system was next to impossible to modify or maintain, and really didn't look all that good when you looked close...you pay a high price later for this convenience...the client and I had problems with the app almost immediately...

In 2000, I took another large DOS app that was DOS-based (Clipper, actually) and used it as the model for a Total rewrite in VFP 6.0 and although it took much longer (4 months instead of 4 weeks), it has been well worth it over the intervening 2 1/2 years of operation and enhancments, etc...

Just sounding off...

-Irv.



>>>>Answer me this please. I know it is ill-advised to use reserved words as functions and variables, but what are the consequences of say creating a procedure called 'refresh' or declaring 'isreadonly' as a private variable? I ask because I am trying to find the anomalies in an application delivered by others. The developer is a FPD/FPW hardcore (all SAY and GET, 200+ *.prgs and all free tables), but he put the program on VFP runtime. I want to find out if the quirks I am seeing are related to the inappropriate use of reserved words.

>>>Often you can get away with things but you will be sorry later. It is better to not use reserved words. I have seen applications run for up to six months and then refuse to work again for reasons such as this. Avoid problems when possible. :)

>Well, this project sounds like a "conversion" from FP 2.X into VFP. Did it ever work? Such conversions are a mixed blessing. If you ever want to modify, add or debug you are going to pay a price in time. The purpose of VFP is to reduce maintenance and development, while allowing the possibility of using newer programming techniques and functionality. These conversions can be a serious issue!
