[comp.databases] 4D v2.1 - what happened to the @ wildcard?

pazandak@umn-cs.cs.umn.edu (Paul Pazandak) (01/31/91)

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.

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!
