  1. I am currently busy to create code to read local Borland Delphi database structures. I do not have a Delphi environment to be able to create all situations, and i have one situation that keeps me scratching the back of my head. I got a *lot* of information from this patent file explaining the structure and it got me reasonably far: https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US6151602.pdf The type code descriptions give a general idea, but they whip up examples that i cannot cope with other parts of the information. There is a thing with the optional parameters that i do not grasp: for each column a parameter count field is present but in the "Test_change_Log.dat" the svCHANGE_LOG parameter is added directly behind an svWIDTH parameter, also with a count of 1. There was also stuff i could not trace back within the description, like the data-offset point in the file. It is set whenever the offset point falls within the scope of FFFF, if the data starts much further away, this field is 0000. The below package, contains the source-file with a couple of .dat file examples, you can unmark/remark the specific $DatFile around line 66 to test each file. You need to copy the sqlite3.dll into the source-folder if you don't have it in a spot where it can be always called from. Frankly what this source does is this: Translate the BDE header into an Sqlite header with the exact matching description (if you ever need to translate the contents back into another or same database form using Query2d -> "PRAGMA table_info(DatTable);", you have all the exact entity type descriptors available) Then it inserts all records from the DAT file into the sqlite database. To keep the program fast, it will recap a 2D array query of maximum 1000 records as ArrayDisplay remains slow as hell. I think this is specially appealing to those who are familiar with Borland Delphi or have stuff around that they need to port over. I have also inserted the code for everybody to view online. For those interested in this puzzle: Watch out for these nasty pitfalls: These BDE database files are in some parts written in 8-bit block parts whereas _WinAPI_ReadFile() picks up in blocks of 32 bit. This goes fine whenever your $str structure blocks are filling consecutive 32-bit blocks, but mess up your file-pointer when they are ending in odd 16 or 8 bit particles. I have not even tested when you would compile this source into a 64-bit executable and what _WinAPI_ReadFile() does in that case. But to end with my remaining questions: I do not have enough example files to cover all situations described in the Patent and i don't own a Delphi developer environment that would help me create these extra examples, like:how should BCD blocks be interpreted? IEEE Floats, Timestamps, Date/Time fields etc. How should the optional parameters be read in which order?
