Hello Daniel,
Thank you for your response. I have done some analysis to see what the implications of your suggested approach would be, and have found the following:
The database files are in two parts, the data records and another file with the defined indexes (The C-tree engine requires at least one defined index). The volume of the data files is 16Mb+, which would be too big for the DOS environment. The second restriction in creating one file of this data is that the C-tree engine has limitations on the number of fields that can be included in one .exe file, and the number of fields required for a single file would be several times more than this limit. A third restriction would be the size of the generated file. I have already had to split one of my files into a "current records" part and an "archive records" part, and each of these data files is nearly 2Mb in size. (I am talking about 20 years worth of data in these files). The "current records" file contains 7660 records, so re-typing would be a mammoth task.
So I am back to exporting table by table, importing to an Excel file, then importing into an OutSystems structure.
Regards,
Terry
