Hi, this is one remark I've sent to PC Soft long time ago. They indeed said 'thank you!' but did not change anything I could see.
- Duplicates: You have define such keys as 'with duplicates' and you have to do the checking for duplicate values yourself. This is a rather tiresome exercise, however, there's no way out. I'll have a look and publish some actual code, if needed. Not today, may take a week or so.
- Searching: Other databases - like Btrieve - do regard NULL values as non-existing records when browsing a datafile by a key which can contain NULLs, which speeds up database traversal a lot.
Kind regards,
Guenter
