Some users have had trouble with v2.1. They say that the '@' wildcard in lookups no longer works in their db as it did in 1.0... Are they seeing things or has the convention changed? Thanks in advance for any response!

I believe that the character is the same; however, if they simply used the conversion utility to convert their database, they could be having some problems. The one area where the 4D programming language changed most dramatically was in links (they aren't even called that anymore; they're called relations), and it's possible that their code needs to be changed, or their relations set-up "properly" under 2.1. Personally, I've recommended to anyone who has a 1.0x 4D db that they have someone go through their code, and bring it in line with the current set of standards for 4D programming; their are a number of commands that, while they still are still supported under 2.x, so far at least, are only supported for converted databases, and probably won't be supported whenever 3.x comes out, if even when the next 2.x comes out. Simply using Acius' conversion tool and running with it is not, generally speaking, a good idea.

"Personally, I've recommended to anyone who has a 1.0x 4D db that they have someone go through their code, and bring it in line with the current set of standards for 4D programming;" Any suggestions of who? Would you be interested? And, if so, what rates would you charge? The database was created using Skeleton 1.0, and is not particularly complex. There is about 3.5 MB worth of data though. Thanks for the response! Paul Pazandak.
