DBAS source code

Hi All,

DBAS is the excellent database engine written by David W. Howells and used in my SuQcess database programs.
But recently a problem came to light while using DBAS on SMSQmulator.
It appears that field names can go missing when a lot of them are defined.
My tests revealed that the FLNAME function then returns an empty string, making the names invisible for the user.
The test also showed that this problem is not limited to SMSQm but may happen on QPC2 as well, be it at another point and there is, sometimes, also a difference in behaviour for a QLIB compiled or an SBasic running SuQcess. Sofar it's been very unpredictable.

To help in tracing the problem it would be nice to have the source of DATA_BIN and DBAS_BIN but that is not part of many of the packages I found out there.
Does anyone have or knows who has these sources?

The sources are listed as part of the Quanta library

Hi,

The main problem with DBAS is there is no source code to the DATA_BIN & DBAS_BIN files.

Unless there is an update I do not know about.

I did disassemble DBAS years ago, but I would have to look for the disassembley file.

What sources there are should be on disk SP08, although from memory I don't think the files Bob wants are on there, though.

Phil Borman did an update of dbas, although I have no idea if he worked from sources or disassemblies.
